5.0 Rating Excellent ammo - 7/4/2012
Reviewer: Rick A.
Excellent ammo. I use it with my FN SCAR, HK MR556, FN FS2000, SIG 556, and other rifles. Amazing. If you find it, buy all you can afford. It's clean and accurate.

5.0 Rating MO Shooter/jmarsch - 1/26/2008
Reviewer: Jarrod S. (Hillbilly)
I purchased this brand of ammuntion in 52 grain. I fired this out of my Ruger Mk77 Hawkeye (1 to 9 twist). At a ranges of 100 yards. It punched connecting groups in my targets. I was able to shoot some dime size groups. This ammo is worth the money. Don't be worried about the "Factoty Reload". I conducted this shooting session shooting from the prone position using only a backpack as support. I'm looking forward to hunting varmints with this ammo. Be safe out there Cops. Semper Fi! Marines!

5.0 Rating Ultramax - 4/30/2008
Reviewer: Ammo-junkie
I practiced with some of this ammunition out of my DPMS Arms M4and Olympic Arms M4 with no feeding problems or jams. I shot off of a backpack and produced quarter-sized groups. I'm sure groups could tighten if i had a sandbag on hand. I shot rounds out to 300 yards with no problems doing follow-up shots. I will buy some more in a bit before they all go.

2.0 Rating Shot ~250 rounds - 5/13/2008
Reviewer: ar guy
Shot ~250 rounds and mid way experienced and complete fracture of a shell casing. This caused (2) rounds to lodge in the chamber. A leather man easily removed the casing, but this could have been ugly. Because my RRA has never had a proble firing any other brand from 55gr wolf steel to hornady tap, I'll be steering clear of ultramax from this point on.

2.0 Rating Blackthorne Products Uppers - 6/26/2008
Reviewer: RJ
I have two Blackthorne Products uppers (16" bull and a 24" bull) and this ammo jams all the time. When I use another type of ammo no problem. I have three Bushmasters and one Colt which never jam. Go figure RJ
