Pete,
For the same reason I cannot carry bear bait or pick up a post driver, or hunt with my 1841, I am tired of more pain. Any compression of the back, leaning, twisting, lifting of arms etc and I am fit to be tied. A gallon milk jug from fridge to table is bad enough, and I have even dropped them a couple times. I lost all my muscle mass a few years back from a staph infection that almost killed me.
I use what plumbers did for oakum and lead joints, a propane tank with burner on top, and a cast iron pot on the stand. For me to even think about picking up lead to put in pot...........yikes.
It is not limited to .54 and .58 balls, have molds for .451, 454, 457, and .450 200gr, and others, but anyone wanting to help can make anything they want.
I am still hurting from what little I did on Friday when I loaded the rifle twice. My sweet wife did the the rest and even cleaned it for me!
John
