so, for a 3sb/3sn/.25-.35%Copper alloy, what do you think would be the best choice for hollowpoint pins, short and fat, long and skinny, or other? I was thinking a hp shaped like a martini glass would work good ( short sect. of wide opening, then a longer "stem" of maybe .10 dia ending in a rounded point), if you can picture what I mean? and do you think this alloy should be heat treated or quenched for 2100fps?
