Sizing issue
I have one of them new fangled cartridge rifles, an 1871/78 Beaumont in 11.35x52R. My groove diameter is .451+or -, the bore diameter is .434. If I were to size down any of the Lyman .457 bullets to .451, would the bullet be unrecognizable and unable to be lubed? In my .45-70 BPCR shooting, I cast a 30/1 lead-tin mix. Should I use that, or use musket lead, or hard range lead? I don't want to piddle away $40 on a sizing die and find I need to paper patch it. Thanks.
