I am new to the AR world
I have my rifle picked out with and 18” barrel but am struggling between 7:1 and 8:1 twist
I guess the vision is Winchester white box or similar coyote round and/or military style discounted fmj

Not as much heavy weight 77g or whatever

There is 1000 opinions out there already

Anybody have an opinion, ideally with test results
It seems the tests I have seen it doesn’t seem to make much difference

Thoughts?
