Hi all,
Two things.
First I am considering a 284Winchester sizing die for my Bushy.
Second. I did try using a Lee's 45-70 and it did an awesome job. The sized case is by .002 larger alongside and fits perfectly into the chamber. I did not expect this good of a result. I am using 45 LC bullet sitting die. I unscrewed it almost all the way out and left just enough to actually seat the bullet and have enough thread left to be screwed into the press. Crimping is the worst part. Tried using 45-70 die. It works fine with lead .454 bullets, but poorly on the regular .451-.452 bullets.
Cheers,
Mad
