New AR-15, M4 profile barrel, chrome lined, 16". Unshot until:
Took it to the outside range Saturday, . . . got a pretty wide grouping at 50 yards. I was using some sort of bulk type ammo. Shot a magazine [30 rounds] worth. Groups looked to be around 4" [again, at 50 yards], using a 4x scope.
Wednesday, I took it to an indoor range with an excellent bench setup. Pulled out some Tulammo [62gr HP] and got the following for 10 shot group [aiming at the center, first two at the bottom to see where it was hitting, "zeroing" closer, then the grouping]:
Now, last night, I took it back to the indoor range and shot the rest of the box, and for some reason, it grouped a lot better. . . . for steel case bulk stuff.
I also took it out to 100 yards and shot some 60gr. TAP and here's the results [5 shot group]:
Maybe I had it more solidly on the bench. Now, I've only had 55 rounds through this rifle thus far. I'm planning on putting the steel case stuff away and using brass from this point out. Anyway, I'm pleased with these groups. Oh, the 100 yard group POA was the mid point of the target between the two smaller lower targets.
