DO NOT USE bullets that are larger than .277" in these 6.8 barrels, 99.9% of all .270/6.8 bullets made are .277" diameter. The chambers were designed for .277" bullets and all 6.8 barrels have a .277" bore so bullets larger than .277" will cause excess pressure and increased copper fouling. It seems some Cavity Back bullets are .278" and on top of that they are solid copper so check the diameter of the bullets before using them.
