I'm looking for a good bullet to use in the 45/70, after I've throated it. As per Leftoverdj's instructions, I want to have the bullets on hand to set the reamer up. I wanted something in the 500 gr. or bigger range, any suggestions? I don't cast my own bullet's, yet, but if needed I'd look in that direction. I did find this company: Jae-Bok Young's Bullet Casting at
http://competitor-pistol.com/jb%20bullets.html He has some interesting heavy weight .459 bullets. Check the one called the Crater.
