Bushmaster is the 1:9 pencil barrel and it should like the lighter bullets better but it holds a tighter group with the 62gr over the same shaped 55gr. I would have preferred a 1:8
Same, the 1:8 also seems to be best of both worlds for both ends of the spectrum on a wider note vs whats appeased by the 1:7 or 1:9 twists. Plus these 4 80% lowers (was 5, shat one into a cool paperweight) are all built for under 225 yards. If I need to get out farther I have better options and still improving on those (and other options mostly in multiples). And anything less, well.. I'm only a trail camper.., I'll seek my target(s) like a room clearing task if necessary.
I'm still learning about the grains and relative to things from proper MOA, penetration at effective ranges, and the future endeavor to do reloads properly. I've done shotgun reloads for a few years, never rifle or hand guns tho. One day...
