It has been suggested that I switch to a 50/50 mix of WW and Pb for hunting, and I am curious how fast I can push this mix with a GC design in a good smooth barrel of moderate twist. My primary hunting rigs are a 35 Whelen with a 1:14 and a 308 with a 1:12. Both shoot VERY well with water dropped wheel weights, but that would give me zero expansion in game. I thought of trying air cooled WW, but it seems from what I have read that it would be too hard for much expansion as well. I push the WDWW pretty hard, so I know I'll have to do more load workup, the question being what kind of velocity can I shoot for?
