I'm currently shooting 4.2 grains of WST with the 200 grain (H&G #68 style) bullets for 50 yards and for 25 yards I'm currently shooting 3.5 grains WST the 185 grain cast bullets. I also like the 185 grain Paul Schroeder full wadcutters, they cut a HUGE hole in the target!!
I sure wish someone would cast up the H&G #78 bullets and sell them!! Ballisti-Cast sells the mold and calls it their No. 678 mold. That bullet should be the most accurate one for the .45 AR revolvers.
