1/7 vs 1/9 accuracy at 50yds with 55gr.
Would there normally be a difference in accuracy at 50yds for 55gr ammo between 1/7 and 1/9? Reason i ask is today i was shooting my Colt 6920 alongside a friends Olympic AR. They both have 16" barrels but his shot noticeably tighter groups. I was really dissapointed in the difference. The Colt was around the size of a can of dip while the Oly was almost half that with several groups the size of a quarter. This was with open sights and with both Wolf and PMC FMJs. I shot both guns back to back several times to compare. I want to compare some heavier ammo like 75gr. Im hoping the 75gr will shoot better than the 55gr in the 1/7 twist. So is this typical?
