Worked well for what i used it for. - PMC Ammunition X-TAC 5.56x45mm NATO 55 Grain Full Metal Jacket (FMJ) Brass Cased Centerfire Rifle Ammunition

I purchased this ammo specifically to use in sighting my BCA AR15 5.56 and its newly mounted Vortex scope. I am out of practice with my shooting skills so I bought what was on sale and it happened to be the X-Tac FMJ. I found that I was still able to shoot a fairly decent cluster of three and continued until the scope adjustment was complete. I then replaced my target and moved it to the 75yard marker (from the 50 Yard marker) and fired five groups of three. The results were good and I had 3 clusters with close grouping on the bullseye and two grouping that were not so good. I found that at that range , the X-Tac rounds performed well with no misfires and I even took a few shots at the fixed metal targets at 300 yards and hit them several times. I will watch for these X-tac 5.56 rounds to go on sale again and want to try some of their green tip rounds as well.
