I just purchased a used Lyman 429421 two cavity mould this week and cast a bunch of boolits last night from lead that I have been saving for 25 years. In the last month I have been making ingots on my Coleman campstove getting a feel for fluxing and messing with liquid hot metal. I ordered a Lyman kit two years ago that had the 4500 lubesizer, the mini mag pot, ladle and the Lyman manual. After picking out 50 of the best boolits, I sized them to .430. They would fall through four cylinders on my 4 5/8" Ruger SBH and push through the other two with very slight pressure. I lubed the them with a home made lube that I will detail in the Lube Forum. I shot all fifty at the range today, accuracy could be better I'll just have to tweak the load some I started with 8.5 grains of Unique, Federal brass, and Winchester WLP primers. After 50 consecutive shots I pulled the cylinder and was extremley pleased to see no trace of lead in the bore at all. I'm just starting but I think I'm addicted.
