Thanks for your help. I ended up with 72.5 gr RL-22 for my load. It worked so well I changed to a 3.5-15 Nightforce scope and a Stockys stock. If I can figure out how to send pictures, I'll send a picture of the rifle and the 340 elk that I got. It's being mounted now.
I only have one rifle with a detachable mag. The problem I have with it is I'm limited as to the overall length of the cartridge. This limits my accuracy. My best accuracy is when I get close to the lands.
