I have read and been told that a 1 in 7" twist 5.56 barrel will cause 55 grain bullets to sling apart due to over rotation. Has anyone here experienced that?
In the next 6 months or so I would like to get either a dissipator or a 20" A2 profile upper for my next build. The uppers I have looked at at PSA are 1-7 and since I am cheap I pretty much always end up buying 55 grain ammo. Will this be a problem?
