I used to cast a lot back years ago. I was an admirer and follower of Elmer Keith. His experimenting contributed to the development of the 357 magnum and was instrumental in the birth of the 44 magnum. So I used to cast his Lyman 429421 with 18 grains of 2400. Sometimes 9 grains IIRC of Unique.

The thing is and was that the factory 44 mag is so overpowered for recreational shooting that it is uncomfortable to shoot. The 44 special in the factory load is underpowered as they are afraid of realizing the potential of the round and blowing up old firearms chambered for the cartridge.

I have a pair of 44 mags and a 44 special. I can buy bullets already cast but I still have my old Lyman mold and have thought about getting another melting post and doing it myself. The only way to enjoy shooting those is with tailor made rounds IME.

When I was a young man I would cast for hours once a month while chain smoking Camels with no filter and I am still here. Good advice about getting exposure checked with blood work if I do get back into it and the ventilation, thanks. If I do it I'll be on the porch not the kitchen table.
