HalfaDouble,
I have a drilling in that caliber, and I load for it, but not with lead bullets. It' not that I have anything against lead bullets, I just use them in other rifles. The 6.5x57R is a great caliber, I have taken several Whitetails with it and it seems to kill pretty much like a 257 Roberts. I didn't have any trouble loading it, I used RWS cases and American bullets. It is one of the German 6.5s that use .264" bullets like our standard. A friend of mine recently reported problems using S&B cases that have small primer pockets. He is an accomplished machinist and intends to bore them to .2095 from .206" with a mini boring bar. He tried a primer pocket uniformer, but was unsuccessful because the uniformer cuts only on the end and when forced in, it made the pocket oversized. If that is not your problem, I guess I jumped the gun.
Mike
