I got my bullets, now I need to find some load data. I was hoping to use IMR 4227 but I'm not finding much data for it and none in the 340 gr bullet class. Anybody have any older data listed?
 
Well I finally did enough load development to be happy with my results.....I'm putting this up there for anyone who might be looking for load data themselves. I found 26 grains of H110 to be the best for my Ruger Alaskan .454 it gives great groups and isn't too terrible on the recoil. Now if I could only find a bear to test them on
