Need help on a 45-70 mold
I have a lyman 457 400 grain mold for a 45-70. It says it is supposed to cast 457 it actually casts 454 and I have to hammer the hing pin to get the boolit out!
I beagled it and got it to 457. Can a mold be double beagled?
I love the style of this boolit I just need to get it to .4585-.459.
What are my options. I thought my lead mix might be bunkus. So I tried the same mix in my lyman 44 mag mold and it thru .431.
I am at a loss...
Any help would be appreciated.
Thanks
