Well a little while back I posted that I made my first 45-70 reloads with Accurate 5744 (23.4gr) and some 405gr Hitek coated lead bullets. While they shot pretty good and had nice light recoil, after 40 rounds I had a barrel full of lead fom the beginning, all the way to the muzzle. Supposedly they were 13 brinell.
Well I'm used to lead in the barrel( dang 357 Vaquero) so I got out my brush and some Chore Boy and cleaned it out. I've also read that it's roughly 1440 x brinell=psi needed for bullet obturation.
Is it possible I didn't have enough pressure to obturate the bullet? I don't have or know where to get a chunk of soft lead to slug my barrel. Anyone knows where I can go to get one, please let me know. If the bullet fit wasn't perfect, should the hitek coating prevented the leading?
With my Ruger 357 and lead bullets, I upped the charge, which raised the pressure and my leading problems went away. With any 38/357 coated bullet, I never had any leading problems no matter the pressure.
