RE: Sizing .457 Conicals to .451
 

I have a Green Mountain .458 1-18 twist barrel. My rifle likes the Lee 459-405-HB bullet a lot. I pour them out of PURE lead. I size them to .454, then to .451, I use RCBScase lube,and then i wrap them in paper. After I wrap them in paper I size them to .454, and then to .451
These bullets shoot amazing out of my rifle. Ron
