I plan to purchase components for 4 different pistols. 38 spec, 357 mag, 44 spec, and 44 mag. Is there any one powder which will be acceptable for all, and are there primers which will be acceptable for both 38/357 and 44/44. The reason I ask these question, I plan to buy bulk, and want to keep it simple, unless quality is compromized. My shooting is mostly for enjoyment and not hunting or competition shooting. It will be easier to explan to my wife why I bougth 1 can of powder and 2 boxes of primers, than 4 cans of powder and 4 boxes of primers. See my point?
