DO NOT USE bullets that are larger than .277" in these barrels, 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 Maker bullets and Cavity Back bullets made by Maker are .278" and on top of that they are solid copper so check the diameter of the bullets before using them.
