I'm still a relative novice to reloading so I'm looking for advice from some seasoned reloaders. I've got a bunch of bullets pulled from 7.62x25 rounds, they measure out at .308 and 85 grains. The bullets I normally see advertised for .32 acp are .311 and 71 grains. That's also the only reloading info I can find for this round in my Sierra manual. The question is can I use these slightly smaller, heavier bullets and is the weight difference significant enough to be problem in a semi-auto handguns?
