What brand sizing die?? And what size sizing diie did you use?? I am having a hard time finding sizing dies for the 50 caliber. All I can find is a .501.

Did the bullet "slip fit"?? Tell us a little about the loading and sizing comparison between the barrel and the bullet. This is important stuff. I have been experimenting latley, and it is getting expensive, however I am trying to find the "magic" bore diameter to sizing die ratio.

What alloy?? Tom.
