Because it is effectively a .22 short round, and because it has a pointed tip, it does not feed well in many magazines. Only my stock 10/22 mag will reliably feed it. However, the last round will never feed because the pointed tip will not ride up the feed ramp very well. Finally, I think because of the short case there are occasional FTEs which require one to remove the mag and pry out the case with a blade. Still, however, I bought it to shoot in the back yard and it still does that better than I could expect anything else to do, so I will still be purchasing this ammo and recommending it to others. (Editor note: This ammo is intended for pistols only)

Great ammo for practicing in an urban backyard. They really aren't lying when they say it is as loud as a pellet rifle. This round produces 11 ft-lbs of energy, and when you shoot it from a gun designed for cartridges producing 10 times that amount of energy, then you should expect that it won't be enough to cycle the action. Your semi-auto will basically work like a bolt-action rifle. I bought this ammo to get a small taste of shooting without having to bug the grandparents or go to the range, and I am more than satisfied!

VERY VERY quiet in numerous rifles. No louder than a BB rifle. However had TONS of feed problems in 3 diff actions: Iver Johnson pump, Win auto loader, and Henry lever. Shells were not being removed by extractor. Happens about every 7th shot on all actions. Thought it was the extractors but they worked fine with 100 rds of Winchester .22LR. Buy one box to try it out with your extractor first and then get the 500 rd box if it's ok.

I shoot about a brick of this ammunition every month. I live in a Semi-Populated area and the sound of firing a standard .22 LR round does bother some of my neighbors, so I ordered a 50 round box of this ammo just to try. It was really quiet, and performed plenty accurately. Since then, I've shot about three bricks, not a failure or anything. It has performed flawlessly, and I'll continue ordering it as long as it's available. Dovehunter

i just got a small box of fifty of these rounds. i hate to tell all who think the ammo is not accurate it is definitely the shooter. with this ammo can hit the center of a target at 30 yards every time with my 1902 Remington single shot.

I've used these for years. Told my local gunsmith about them 5 years ago and he still carries them and recommends them to me when I come in about once every 4-5 months. He doesn't remember who brought them to his attention. He even keeps a little plate of examples that went through a gallon of water and hit a steel plate. Most everyone has said pretty much what I've felt about them. I use them in an old single shot bolt action page lewis arms rifle. Can sit in my back yard and plink and the only noise is hitting the can or target. They are a lot quieter than my pellet gun and better than that, the only noise is when they hit. I've literally shot them at the ground to show people how quiet they are and they are amazed. I've made money for Colibri just doing that. Anyway, they do wonders on just about any pesky little critter that shouldn't be on your property.

this bullet is very quiet out of a rifle barrel, but no quit out of a short barrel pistol. out of a short barrel pistol it's almost as loud as a powder round. really cool ammo this is.

Okay. We all want a quiet (silent) round so we can shoot where ever & when ever we want. We REALLY want an appliance that silences our gunfire regardless of caliber, but that ain't gonna happen. I shoot this stuff with a lever action Browning and it truely is as quiet as a pellet gun (long gun), and is quieter than a pellet hand gun. The impact is sweet too. I shoot with open sights so the effective range of the bullet plenty satisfying. Don't be a crybaby about the accuracy! Its pretty damn good for just 500 FPS man! My only gripe is the piles of brass I'm creating. I fired some rounds through a revolver recently and, as every one else has reported, it's loud. Actually a loud "bang" that definitely sounds like gunfire. I have not experienced any abnormal dirtyness or barrel leading. I run a few patches through every 4 or 5 boxes which seems to take care the crap. I've just finished my first brick and today I'm ordering 2 more. I used to shoot at the deer on my property with .22 cal pellets via a nice Beeman rifle. They'ed flinch and trot off. These rounds give those deer a real smack on the back-side and they run off like their tail is on fire!

Very quiet in a rifle barrel. Just a little snap and the impact is a reasonably stout thud. I've never gotten it stuck in a 22" barrel and don't think it would be very likely. I also have tried it out of my NAA Black Widow. I thought it would be fun to use around town, but it is very loud. About as loud as a standard subsonic round through a rifle. So if you want to be shooting your little revolver around town, you'll have to look elsewhere.

Works great in my Walther G-22 rifle. Not enough to cycle the bolt in it but it is well worth it for not making a peep! I shoot in my basement and all I hear is the projectile hitting the target. I purchased recently bought a 500 round pack from this site. Fast shipping, great price, and an awesome product!

I love these little bullets and have shot several thousands of them. They are not pinpiont accurate like a long rifle bullet but at close range they do the job. They will fly differently depending on what gun I use. With a Rem. 597 they can be watched through the scope get past 40 feet and start to get strange flight characteristics and sometimes they stay straight as an arrow. With a CZ bolt action they allways fly straight as they can. The 597 has looser rifling than the CZ but, it could be the bolt stays tight on the CZ. A friend of mine uses an old Marlin bolt action and has good accuracy with them. Whatever the reason they are cheap, effective against critters, and quite. When shot from a revolver they can easily be seen flying throught the air on bright days making them a little like using tracers. Just add more lead, elevation, windage etc..........

I tried using this ammo in my G22 rifle and it worked great and it was super quiet i recomend this buy with two thumbs up.

This ammo is very quiet when fired from rifles, (loud as a pellet gun) but accuracy isn't very good. Plus, you'll need to clean out the lead deposits in your barrel. I was shooting at a 3" paper target at 20 yards using single shot rifle and a low-power scope and went through 20 rounds of this ammo before giving up. I couldn't get a bullseye for the life of me, but did hit the target, at least.

Wow, these are just great. I was outside shooting and the people inside my house couldn't even hear them, they weren't aware that i was shooting until i came inside with a hand full of empty shells and a rifle. Great for a squirrel hunt, which is what i'm doing tomorrow morning.

Purchased several bricks and I am very impressed with the accuracy & power. Easily penetrates into one wall of a sturdy coffee can at 50 yards. 1 1/2 inch groups at 35 yards (not on a rest) is common for a skilled shooter. Very quiet when used in a rifle. As loud as a 22 short when fired from a handgun. I have fired over 1400 rounds in bolt action, lever action, and semi auto rifles with no problems whatsoever. Please be sure of your backstop! This ammo will penetrate 1" wet plywood at 25 feet. Great knock down power when compared to a .22 or .177 pellet rifle. My friends who have used this ammo all had the same response - "WOW", & you will too.

These are great in my 597. They really are as quiet as a pellet gun and have a good amount of force behind them. My Walther P-22, on the other hand.... Sounds a bit louder than a cap gun indoors. You could easily get away with shooting them out of a rifle in town, but not a hand gun. I shoot into a large box inside, filled with olds towels and clothes. They will go through a few layers, so over stuff it. I have a long hallway in my house and use it as a range. It's a great alternative to paying for a range or going out to plink in the cold.

this is a good ammo for playing around with, not very lethal ,very loud in revolvers i want to try this through a walther p22 i have fired it through a ruger 10/22 rifle i have to manualy cycle every round if you want something with more power with less noise i recommend you get a silencer/suppresor for a .22 and shoot remington subsonic .22 through it or get a 9mm silenced glock with remington subsonic 9mm.

I bought some of this ammo from my local vendor and fell in love with it and had to get a brick for my next trip out to the range. Great Stuff!!!

Great ammo. I'm shooting this through a North American Arms .22 Mini Revolver. Sounds like a cap gun. A little bit louder than my bb-gun but not by much. Very fun to shoot.

This ammo is very quiet and is plinking accurate at under 25 feet. People make astounding accuracy claims with it, but 6" or larger groups at 25 yds is more realistic. If your rifle has a high power scope, under the proper lighting, you can actually see these rounds in flight. Oftentimes they're wobbling erratically in flight.

I love this ammo, I eliminate mice in my homes during fall and winter with out the wife knowing I am do so. Strongly Recommend it... A+++++ Super Quiet. P.S. Works great with Single Shot Bolt Action Rifles.

Takes out the little enemies in my yard. Very quiet, but it's like hitting them with a howitzer. Wouldn't shoot them past 30 yards. Recommend a bolt action for the quick follow up shot if necessary.

this ammo shoots very low at 15-20 yards but readjusting the laser dot was no problem. At 20 yards i can put 5 shots in a nickle sized circle. Every round has fired so far and no bullets lodged in the barrel. Great fun for basement shooting

Lives up to the name super quiet - just a bit louder than a air rifle. I am using in a AR-15 .22 conversion & the only problem I have is that I have to cycle each round manually. I just see it as a trade off.

I was given a box by a freind to use in town. I have my own brick now. It really gives my kids a chance to target practice in the yard. Varmits are no match up to 30 yards with a 1/4 inch 10 shot pattern. With a busy schedule and no time to goto the range. I can spend time with my kids and let them enjoy shooting. All of my bolt action rifles have had no problem. Not one has failed to leave the barrel. I am still cautious. 1 pop 1 hit. Any doubt, check it out. It makes less noise than any one of my pellet guns. It penetrates the same as my 780 fps .177 pellet into a 3/4" pine board. I already have to get more. Be safe shooting.

This stuff is GREAT! Far quieter than my 1000FPS pellet rifles. My friends are always wow'ed by this stuff. I break the rules and use it in my 10/22. I've never had one get stuck and I use it all the time. I've killed many many many gophers with these. So quiet that people around the park never even turn their head. A car door closing makes a lot more noise. Most of my shots are taken within the 50ft range and it's great at what it does. Stops varmints without drawing attention.

I have a p22 with a Tac 65 suppressor and there is almost no sound when firing this stuff. It is so cool. only problem is i doubt it will kill anything bigger than a bird since the 20 gram bullet bounces off the ground.

Bought some of this with the idea I might use it indoors. Won't kill my ears out of a 4" revolver, but I'll use muffs if I plan to shoot more than a few. Fairly powerful for a no-powder .22 round. This will take a chip out of a cinderblock and will penetrate a certain amount of wood, so make yourself a proper backstop / bullet trap for indoor use. Overall, I really like this ammo and will always have some on hand.

I just hear a click from my cricket 22, but with my buckmark I hear it snap...I love the ammo and im gettingmroe of it right after this review! :D

I love this ammo so much.

I fired this through a Walther P22 with the 3.5" barrel. As noted it will not cycle the semis, so I wasn't concerned about that. What I was concerned about was the noise. I'm glad I went to the range to try it, as it was noisier than I imagined from the previous reviews. Had I fired it in town I expect I would have had a visit from the local law enforcement. It sounds more like a small firecracker going off, than any pellet gun I've fired. Having said that it was extremely consistent, I was nailing a plastic jug at 100ft with the Walther P22 every shot, after recycling the pistol every round. I guess I'm going to have to find a small 22 revolver to shoot this ammo. It is fun to shoot, accurate, and quieter than most 22 ammo out there, but not as quiet as I thought it would be, hence the 4 bullets rather than 5.

This is a good round to use for farmers and ranchers.I use it for taget practice in a little town. This is a quiet round good for hunting rabbit and and other small game at night. Perfect for snakes too! It is little less powerful than usual bullets but can kill rabbits birds and can shoot through soda cans! I love this round!

i used this ammo with my stevens model 35 bolt over the past years i have taken out over 10 rabbits from about 20yds each time and get instant results and my neighbor hasnt complained at all since ive started using super colibri rounds

The Aguila .22 Super Colibri bullet is a little quieter than CCI's CB Long, and a little less powerful. Be careful when shooting around rocks because it's prone to ricochet. But OK to kill chipmunks, squirrels, snakes, etc. Can be used indoors with proper precautions to prevent ricochets. Have not experienced any problems using it in long guns.

These shells work great out of my Rem Field Master. No more crows waking me up and no more unwanted birds around the Song Bird feeders. I shot and killed a crow last week that I would estimate close to 150 feet away on a flat ground shot so the shells pack a punch if you can place the shot correctly. I did notice the shells arch some what like a BB gun but after about 75 feet they flatten out. If you have any pest from Crows to Rats you can't go wrong shooting these shells. Great in bolt action and pump 22's with very light noise. Will go through 1/2 inch wet wood privacy fence as I found out. Can't go wrong if you have a need to shoot a 22 in the city limits.

very good ammo, no longer have to deal with the cops coming to my house cause the neighbors get angry about the noise of regular .22 ammo. now i can kill those pests that everyone hates. i can finally shoot my .22 with the neighbors on their porch and they don;t know what i am shooting. very good ammo and great for the price. i recommend this ammo to anyone who has neighbors that hate you shooting out back

fast like airgun,kills rabbit like airgun,but it sounds lesser than airgun

I have used this ammo a lot over the years, out of my 10/22 you hear the hammer go "click" then a "plunk" when the bullet hits my backstop. From a revolver, its a "tad" bit louder, it allows a lot of practice, almost no noise and the neighbors dont get upset.

I have shot squirrel, rats and pigeons w/ this ammo. Recently tried it on rabbit at 20 feet and was downed immediately. This ammo can still do some serious damage. IT WILL penetrate thin plywood and drywall so be careful where you shoot it. Is very quite out of my 16" barreledCZ bolt gun. It makes resepectable groups. For those who can't acquire silencers in their state, this is the way to go. I once saw bricks of this ammo being sold at my local gunshop and bought them all. :)

i own a sig mesquito and both me and my friends love it! it works nearly perfectly and is hands down the most quiet .22 ammo in a silencer! if your a class 3 type of person this is indeed the ammo to use if you have a .22 cal suppressor! slide slap quiet with my gun but in a bolt action .22 rifle it make almost no sound what so ever! the only draw back is it won't cycle my sig but thats not a real problem for just short range applications like indoor target practice. all around great product!

Yes this bullet is the best for plinkin around.I shot one the other day in freinds backyard.So i would highley recomend it

I have a short range shooting range in my basement and this ammo is great- I use large cardboard box for backstop with several sheets of light sheet metal interspersed. I have never had metal penetrated at a range of 15 steps. My wife never cared about shooting but when she saw me shooting this she asked to try it and is now hooked. She is s southpaw and can do as well as me. I shoot a Colt Frontier 22 single action, a Ruger single Six and a 45 Colt Peacemaker with 22 cal conversion inserts. This allows me to spend a lot more time practicing safely.

This ammo functions best in revolvers,and clip fed bolt actions rifles. I have fired hundreds of these rounds and never had one fail to leave the barrel.I've used them to keep the squirrel population in check,and as you will read in other posts,they are quiet and effective.

I have to say, this is really the best specialized ammo you can get for the money. It's dirty, sure, but it's quiet. It doesn't even make the sound a Pellet rifle makes when it's fired. It's also accurate to about 50 yards, which is the perfect distance to peg a squirrel, rat, or other small pest in your yard. The other great thing is your neighbours will never know you're using a rifle, they'll think you're using a BB gun.

I was first introduced to this stuff by a friend, and I have been hooked ever since!!! If you need to dispatch small critters without angering the neighbors, this is the ticket. I have used a pellet trap at a distance of 40 feet and have yet to loose a shot, great for backyard/garage practice or getting rid of small unwanted guest in the garden or backyard.

This is absolutely the best ammo to use if you want to just shoot around out back with out having the neigbors call the police on you. These are super quiet the exact loudness of a pellet rifle. About the maximum effectiveness range is somewhere about 50 yrds. If your buying them for a rifle you will have to single feed them like I do for my 10/22 they are not powerful enough to cycle the bolt so you dont have to worry about jams. CCI has some that are pushing at 727fps. I'm going to try those next maybe they wil have alittle more power while still remaining pretty quiet like these 500 fps.

When I got my NAA mini-revolver for my birthday, my husband knew I would be so anxious to shoot it he bought these Colibris with it. I stapled a target to a pallet we have in the backyard and shot away. It does make noise, but on a Saturday evening with the neighbors playing their radio and all the kids are running around screaming, no one would be able to tell you're shooting your gun in the backyard. Not half as much fun as snake shot and I wouldn't use them for real target practicing, but when you can't wait to get to the range, these do just fine!

AWESOME AWESOME AWESOME AWESOME AWESOME AWESOME I'VE PURCHASED OVER 20,000 ROUNDS OF THIS AMMO. YET TO HAVE A HANG FIRE.... MAKES FOR A GREAT SATURDAY AFTERNOON, BACKYARD SHOOT. ELIMINATEDS YOUR SQUIRREL PROBLEMS TOO. I DO USE THEM IN MY "HENRY, LEVER ACTION" WITHOUT ANY PROBLEMS, JUST KEEP YOUR RIFLE CLEAN. AGAIN: AWESOME AWESOME AWESOME.............. DAN P. EASLEY, SC

I have been using this ammo with my kids in the back yard and love it! I have a Cheaper Than Dirt 22 cal bullet trap, and we have competitions with paper targets on the trap with this ammo. I don't have to worry about a round that misses the trap when introducing a new shooter to the sport, since a piece of 3/4 inch plywood propped up on a picnic table behind the trap easily stops the bullet. There is adequate muzzle velocity to assure accuracy at ranges easily to 20 meters where we use it. I have yet to get a complaint from a neighbor.

This is the best ammo for the city I can deal with my rabbit problem all day with out hearing a thing from the neighbors. I would only recommend it for micro grove riffled long guns its so slow you could get a lot of fouling fast in a regular long gun I love this stuff.

In the woods of NW Arkansas, noise can carry a long distance. I bought a brick of this ammo to try and control the ground squirrel population that was tunneling around my house. I had a Winchester 1000X and it was pretty loud. This ammo is about as quiet as can be. Sounds like a twig snapping or a popcorn popper. I shoot a Rossi 22 rifle combo and no problems at all. I still make double sure that the barrel is clear before I load another round. I would like to try the CCI version of this ammo but have about 250 rounds of Aguilla left.

hey Levi, I too think these are so much fun, that I bought 20,000+ rounds..... ya, bring the price down a little guys...... these things are AWESOME....... backyards, squirrels, and just plinking.... they're fabulous....

This is lots of fun to shoot and has functioned flawlessly in my fairly ancient Stevens single shot bolt action. (Not supposed to fire in a long barrel, according to the new boxes, but it seems to work just fine. Somebody had a blockage experience, I guess. So be careful. have your lawyer call my lawyer before using this stuff in a rifle.) It is quieter than a pellet gun. We tried to tell the difference between a dry fire and a discharge -- no difference in the rifle. Works well in a revolver, though there is a small discharge noise. Bullet is slow, so you can see and hear the downrange impact. Perfect for indoors (where legal, my lawyer made me say that) and truly fun outdoors. Not like anything you've tried. Buy a brick and trade away a few boxes to your friends. You won't be disappointed. MUCH fun for the money.

I FIRST BOUGHT A FEW YEARS BACK BECAUSE IT WAS $5.00 A BRICK. THE SALESMAN SAID IS WAS QUIET .22LR AMMO AND BOY WAS HE RIGHT. I CAN SHOOT THIS AMMO IN THE BACKYARD WITH ALL THE NEIGHBORS OUT. HECK IT’S QUITER THAN MY PELLET GUN. HE SAID IT WON’T CYCLE AN AUTOMATIC RIFLE BUT THATS OK BECAUSE ALL I GOT IS A SINGLE SHOT WINCHESTER. I HAVE KILLED MANY OF SQUIRREL WITH THIS AMMO AND I CANNOT BELIEVE THE PRICE NOW IS $20.00 A BRICK! OH WELL, IT IS WORTH $20.00 BUT I SURE DO WISH IT WAS $5.00 A BRICK AGAIN. I WOULD BUY A WHOLE MESS OF THEM.

I found this ammo to actually work in rifles as well as pistols, very quiet, I recommend it for anyone who is looking for low noise ammo
