I believe that shooting cast lead bullets at too high velocities will increase leading in barrels. Is that a true statement? If so, I want a fairly mild load for 9mm cast lead bullets.
In my Speer reloading manual, I can find load data for a 9mm 125 gr LRN bullet using a minimum of 4.1 grains of Unique powder (911 fps).
I happen to have a quantity of 115 gr LRN bullets, and a quantity of Unique powder.
Since the weight of a 115 gr bullet is 8% (or so) less than a 125 gr bullet, can I cut the minmum load of Unique by say 10% to find a good starting place for a load of Unique under a 9mm 115 LRN bullet? Say, 3.6 or 3.7 of Unique?
Logical?
