"Used this ammo on the range last week...no misfires, loaded perfectly every time and you can't beat the price. I've already ordered more!"

"Have been doing a comparison of accuracy of different brands of ammo in a Mini 14. White box Winchester tied for the best with groups half the size of many of the others."

"I've shot about a thousand rounds of this stuff with no problems what so ever. The cases are also left in real good shape after fired. good FMJ plink ammo made in the USA."

"I put a couple hundred rounds of it through my M4 with no problems, good groupings and I'm gonna buy more."

"If I'm not mistaken the Q3131 with the suffix \"A1\" are from South Korea. Still mil-spec M193 ammo and a great \"bang\" for the buck! Ordering more of this stuff."

"Correct previous reviewer, Winchester has had three codes for this ammo. Q3131= made in U.S.A. (some QC problems), Q3131A= made in Israel (best M-193 ammo EVER manufactured)and Q3131A1= made in R.O. Korea by PMC (great ammo but a bit slower than Q3131A1). I get 2 MOA accuracy with this ammo with no FTF's with my 1:9 16\" Bushy. Velocities are always given as a \"best case\" scenario so look to get approximately 3175 ft/s from 20\" barrels and about 3050 ft/s from a 16\". Nevertheless the extreme velocity of this cartridge will insure a devastating fragmented wound. At this price you can't go wrong."

"I consider this Winchester white-box my staple for 5.56 ammo. I've tried many other types and brands and for the price, you can't beat this. If you want to examine every single Lake City casing for dents, be my guest...I'll stick to fresh Winchester brass, throw it in my mags, and shoot without any second guessing. Thousands of rounds fired and not one hiccup. You can never have enough of this stuff."

"Buy it now, it already went up in price by almost a $1 these past two weeks. Fires GREAT, awesome ammo, fired 400 rounds through the LMT, not one jam! not one! highly recommend this ammo to anyone who wants to shoot, not deal with jams, and for a great price. Ammo is clean too, but any good gun owner still does a good cleaning after every shooting."

"My AR-15 loves this stuff and you can't go wrong for the price. I had a super grouping at 100 yrds. I shot 40 rounds and my barrel still looked very clean. I shot 40 rounds more of this ammo and still very clean. REMEMBER this is 5.56 not .223 AMMO. Just read the article on this web page as rifles chambered for .223 may malfunction or worse."

"I purchased 200 rounds, and I just can't say how good this ammo is. It is very accurate and packs a punch. Also VERY CLEAN! I'm just hoping the price drops a little more so I can buy 2000 rounds."

"I used this ammo to break in the barrel of my new YHM-15 using Magpull mags. 140 rounds without a hitch. Not sure about accuracy because I was sighting in my Magpull flip sights and I haven't shot in years. I will be buying again."

"My Daniel Defense M4 and MSAR AUG clone love this stuff. They both chew through this stuff with not so much as one issue. It is accurate and I love the way this stuff smells after a magazine or two."

"I've shot hundreds of these rounds through my Bushmaster XM15. They are some of the cleanest and most accurate I've used so far. I recommend them to anyone using 5.56mm rounds."

"This stuff is fantastic... am not going to lie... All though the FNH Scar I was shooting was designed to fire durkha durkha made ammo in the sandbox... and anything else you can pick up... the only drawback is that its made in Korea... huge let down... like buying a John deere and finding out its made in China... Winchester should not out-source... Ill pay a dollar or two more for american made products... if this product was u.s. made... easy 5..."
