My little brother scored me a 4# can of Alliant Pistol Powder!!! It will be next month before I get it, but I am almost out of my present powder. Prior to this time I was using 4.5 grns. of Bullseye and 5.4 grns. of W231. I would like to know what would an equivalent load of Pistol Power would be. My Lyman book (which is vague) shows starting at 6.2 grns. and max at 7.4 grns. I usually try to load in the middle of the road so the recoil is close to mfg. Also would like to know, since this is slower burning, how dirty is the powder and has anyone ever had any problems? Bullets used are Berry's 230 grn. plated round nose. Any help would be appreciated. Thank you! I forgot to add, my COAL is 1.250. I load all my .45's at this length.
