I got into muzzle loading when I was 19. Found out quick that I had to cast for my .58 caliber Zouave and .44 Remington and Colt 1860 revolvers. When I turned twenty-one and bought my first .45 M1911, I almost had a shock at the cost of 50 rounds of Winchester Hardball.
That's when I started to reload, cast my own and save all the brass I could get my hands on.
Now at 57 I have more molds than I need and more lead than I'll ever use. Buying propane can be a bit of a jolt sometimes.
