I just purchased a LEE 356-125-2R mold and cast a bunch of them up. My purpose is to use them in various 9mm Luger handguns, most of which date all the way back before WW-II and on up to the Viet Nam war. I know that I am supposed to slug all of these handguns, and then load individually sized bullets for each one and load for each one also. But I don't really want to start out with all of that effort. So, my question is, what sizing die should I start out with just to get some shooting projectiles that will most likely work in most of these old handguns? I have been shooting jacketed bullets that measure 0.355" and some kind of purchased red coated bullets that measure 0.356", all with fair accuracy.
