I am using it for deer hunting and if you’ve followed some of my previous posts I’ve been casting devistators and lee 240gr HP boolits. I casted all of these with 49% ACCOWW, 49% pure lead, and 2% pewter. I casted up 10lbs of lee 310’s today with the same mix. They all will be PC’d and GC. I am shooting them out of my ruger 77/44 with w296 and h110 with some healthy loads...21.5 to 24 gr. If I decide to use my lee 310’s I’d like to make sure I cast it soft so I will get expansion at higher velocities. Is my 50/50 mix going to give good expansion on thin skinned game like whitetail? If not how soft can I cast it without slumping or leading issues?
