Am interested in reloading .45ACP, 9mmLuger, and 38Special, using .452/230gr cast bullet for the .45 and a .356/125gr cast bullet for the 9mm and 38 revolver. Question:: Is it possible to find a suitable single powder that will work in ALL these loads, two being semi auto and one revolver? (I note many powder possibilities with the .45 and 9mm, but few options given for the.3. I am looking for target loads that won't bang the heck out of the pistols and yet will reliably cycle the actions, and I think it would be great to get one powder to accomplish my needs. Casting molds are RNL from Lee, and I was told the .356 mold would work for both my 9mm and the .38 if a crimp were applied to the .38.
Also, I note that several loads given for .45ACP in the latest Lee manual will list the same starting load as the do not exceed load. Example: "Bullseye 4.0 start grains, Never Exceed 4.0grs" and "Unique start 5.0 and never exceed 5.0" I am curious as to why there is not a range between start and never exceed, so a person could safely work up to a suitable load. With the data presented it looks like if I were off by 0.1 gr I would be in trouble.
Any observations/comments regarding the above issues are appreciated.
