it so un-uniform as to what gun likes what bullet best or what twist rate stabalized a 70gr best or what twist do I need to shoot a 168gr best. The only way, and i repeat, only way to know what works best in your gun is to actually shoot it and test. Example, i ordered two identical 24" barrels for myself and a friends AR to do an upper build.
