Same. I've shot a lot of groups where 3-4 of them look great and the 1-2 outliers make me think it's a trash group. Then I'm pleasantly surprised when it's still a .8" group.Random thoughts......first I'm often caught off guard how good groups for .223/.224 etc. measure when looking at them. I often shoot a group under 1 MOA and think it doesn't look very good just because of the "spread" that's allowed due to the small bullet until measured.
I think 7 twist originally caught on because "mil-spec bro!" and then hung around because the general consensus is that faster twist is needed for heavier bullets and heavier bullets tend to be match bullets that are more accurate. So people took that to mean faster twist=better accuracy.
Obviously it's not quite that simple, but given how retarded most people on arfcom or reddit are it's no wonder that this stuff is so prevalent.
Not saying 7 twist is bad, but given the bullet weights you can fit in an AR mag in 223/5.56 I find 7 twist to have no advantages and potential for some disadvantages.
