I have several different cast RNFP lead .313 bullets from 87 gr to 112 gr that I use for cowboy shooting in a Ruger .32 H&R mag. I just picked up a Colt 1903 Pocket Hammerless type III .32 ACP. I read the .32 ACP five page discussion so would like to know the max weight I should shoot. Also is there a different weight spring set for .380 than the .32. Wolf only lists one set used for both .32 and .380. If different where do you get the .380 springs. It's a new world shooting cast in my autos.
