Now I see. None of this was brought to light in your original post. (What I have been trying to do is to shoot a full bore conical other than a pure lead concial. With the advent of the 50 caliber pistols, there are some really nice 50 cal. bullets on the market. Of course these are not designed for a ML so some work on the bullets is needed. What I have been trying to do is to create a knurling on the bullet that increases the diameter of the bullet from .500 to .5015-.502.)
Your subsequent posts showed targets with nice groups but never stated that they were from your new knurling process. Do you think the same would hold true for jacketed bullets too of .50 cal.
