I got out this afternoon to check zero on a scope after re-mounting it. The barrel is a 1/9 HBar from DPMS. I put it together with the YHM float tube a couple years ago, mainly for prairie dog shooting. I have only fired bullets in the 40/50/53gr class, all VMax.

Today I had a few different rounds on hand and gave them a try. The 53 VMax, 75gr Hornady BTHP, and 77gr Nosler BTHP all grouped around 1/2" at 50 yards. The M855 was a little looser.

Anyway, just thought I'd share. It was about 25F, elevation 4300 ft.
