Nero,
This is all very interesting, I always thought I would like to get into it,but never did. I helped my late friend Gene Enterkin make .358" bullets for custom ammo he sold in .358 Enterkin Mag.This was well before the .358 G&A Alaskan and 250 gr. bullets that would stand up to the 3000 fps were not avaliable.I was impressed with the process, which included soldering the core and jacket together.Alas, his "outfit" was sold and I couldn't afford it.
