223 Wylde vs 556 accuracy comparison

Differance is in the chamber throat.it makes a difference in the chamber pressure.hunting rifles in .223 has a 1-12 or 1-14 twist..223 in that twist stabilizes lighter (50-55-60)grain bulleted.to stabilize 69-77 grain bullets needs 1-7 or 1-8 twist rate.your right about all the variables in ammo.its as close to witchcraft as it gets.wylde is nice cause it shoots bullet weights 45-77 grains in 1-7 twist.on other hand there's so many combinations of bullets and powder charges.fun and aggravating if you reload.caldwell has a rest that clamps forearm firmly and even if you have to borrow or swap a higher power scope.its not fair to say a rifle or barrel is no good if you shoot a 5 moa red dot at 100 yrds.not many barrels shoot steel case ammo very accurate.some shoots a 5 inch group with a accurate barrel.i seen a test of how much a rain drop throws off a bullet.how about showing hand lapping or fire lapping to see if it changes accuracy?another good vid,thanks
