Yup, it does take some jingle to get set up casting, for sure. Then again you can cast out just the bullets or balls you need.
Pure lead is easier than ever these days. The stick on tire wheel weights are near pure and they are easy to ram and shoot just fine. I have been shooting them for quite a while with no problems. Fact is I get so many of the stick on weights in buckets from the tire shop, that I have a stock pile of pure ingots going and have to keep my supply of straight wheel weights replenished.
A trick or a way I get wheel weights is that I bought a couple molds off of Ebay of soldiers and indians. I had to modify the air channels a bit with a dremel, but they cast out fine. So, I cast a bunch out and then paint them with acrylic enamels and go to the tire shop and hand them out explaining that is my hobby. Works like a charm. I get buckets of wheel weights loaded in my truck for zip. I always bring them a bucket or two and they appreciate that. I appreciate not having to buy them, since it does take some time to melt down, flux and cast out in ingots.
I made casting a part of the overall hobby and set up with the Lee pot and some accessories. I bought the molds I use for C&B and bullets and in a few short hours I can get a good number cast out. Lubersizing I don't care for and only do rifle bullets, others I just pan lube and shoot them as cast. I am thinking hard right now about a shot caster. Shot has risen a lot lately and I am trying to decide if the investment would be worthwhile.
Casting balls at two at a time goes pretty well, but you sure get spoiled with a 6 gang bullet mold.
