Just wondering if I can fire a silver bullet without damaging my guns rifling's. I know that silver has a tendency to expand alot more than lead when heated, and I know that it's less effective than copper and lead, but I just wanna shoot some for fun. (I'll be making the bullets myself, using a mold. The caliber is 7.62x39mm). Thanks for any info.
There's only a few small problems but most should be correctable.
Due to expansion issues, you may have to cast slightly over size and then run through a sizer die or if you mould is of the gas check design, then just use a gas check.
You may not get good fill in your mold, so you may have to add another metal to your silver if your bullets keep ccomingout deformed. -Gut instinct says maybe a little tin.
Lastly, A steel mould would work best. If you use aluminum, you may run a risk in damaging it due to the extra heat needed to melt silver and the preheating of the mould in order to get good fill out.
