RK,
If you want to cast balls, get yourself a 36. As Gatefeo says, they should take a 380 ball and they are hard to come by. Just bought the last 300 from Barkerstown, and the guy says they might be the last 380 Swaged Ball in the country, as he can't find another supplier.
You can buy all the swaged 44 you want, in whatever diameter. Cast some 380.
If you want to have fun and save some money, cast your 44s, too. I found one site selling pure lead for 95 cents a pound, shipped. About 48 ball to the pound, 2 bucks a 100, where you're probably paying from 7 to 9 bucks a 100.
Electric melting pot for about 40 bucks, 22 bucks for a double cavity Lee mould, complete with handles, 20 bucks for the first thousand balls worth of lead. 80 bucks spent, every ball after that is 2 cents each, plus your time, which you said could be an enjoyable winter past time.
Lead can be got cheaper at a scrap yard that takes in old lead pipe from old house renovation, or talk to plumbers in your area, ask them if you can buy the old lead pipes. Lots of crud built up in those old pipes, so don't pay scrap yard price for it. Lots of dross to skim off the top of the melter, but the pipes were pure lead.
I don't think you will see much difference in shooting the 2, cast or swaged. Swaged is easier for the bullet maker, feed a stick of lead into a cutoff tool, cut off, sa, 145 grain chunk, drop into a set of dies, all automatic, force the dies together, out pops a ball. Faster than casting, the lead gotta chill enough to open the mold, so more money per hour of machine time.
I don't think you'll see a difference in shooting. You gotta swage it into the chamber, making it shaped just a little like a double ended torpedo, 454 front to back, 450 side to side. It ain't round no more. More like a just barely conical with a round bottom.
Then, too, measure some of them swaged balls you bought, 8 or 10 different places around. Be at least 5 or 6 different dimensions, just from being banged against each other in the box from shipping. Did that last night with the 380 that just come in. 377 to 384, dimpled like a golf ball.
Damn, I was gonna buy a mould to give the s'in'law's old man, a casting fool, to make ball for me. Now you got me thinkin' I should buy a melting pot and have somethin' to do over the Winter.
Cheers,
George
