In all honesty I had to pick both. But, in handguns it is 100 percent cast bullets be they plinkers, hunting of slf defense. In rifles, I probably shoot more cast bulelts than jcketed, but it does depend on the rifle in question. Again, in the 30-30 it's 100 percent cast, about 75 percent cast in the .308 and 30-06. I've been shooting my home cast bullets since I was 16 and I'm pushing 73 as I type this. Don't see any reason to quit now. I've taken deer and small game with cast for years, usually in the 30-30. With the lighter gallery/small game loads, I have found out that the marlin is much friendlier toward those 100 to 120 gr. bullets than the Winchesters based on the m94 (M55 and 64) The Winchester M54 will shoot just about any cast bullet well as it is a bolt action. FWIW, favored, by me anyway bullets for the 30-30 are the Lyman #311291 and the RCBS #30-180-FN. Seventeen deer have gome to my freezer over the years with those two bullets. I'd use them today if I can draw a tag where the 30-30 is feasable. These day, when I do draw a tag, shots are potentially too ar out to use a 30-30 responsibly, especially with cast bullet loads. I pefer to have my shots at 100 yards or less even though I know they'll work just as well at jacketed bullet ranges.
