I use both cast and jacketed. I do use some commercially cast bullets bought in bulk, but mostly I cast my own, especially for rifles. As for using cast bullets for hunting, I've yet to hear of any RCBS 200FP in 35 Remington bounce off any deer. Same goes for the 300 and 405's cast from a variety of molds for the 45-70. A gascheck Lyman 311284 shot out of a 30-06 or 30-40 Krag can not only be a very tight grouper, but a very effective bullet on game as well.
If the supply of jacketed bullets dries up for some reason, I've got the molds and makin's to keep loading and shooting for a very long time--like for the rest of my hunting life. Now, where's my 30-30 and box of handloads (bullet Lyman 311041)? I need to go to the range, and to he** with Speer, Nosler, Hornaday, Sierra and the rest.
