I was trying to figure out a little more about loading lead bullets in 9mm. I have loaded up some 115gr round nose lead bullets I picked up at the gun show with 4.0,4.2,&4.5 gr of Hodgdon Universal. The 4.0 and 4.2 gr rounds wouldn't recoil the slide, and the 4.5 worked with no real problems...except leading up my barrel.... Am I just loading too hot for a non-gas checked round or is the lead just too soft? Is there a cheap way to check the hardness of the lead to see if that's the problem? Thanks for any input.
