For the 7 mag, I' d be experimenting with RL-25 powder and around a 150 grain pill for deer. I' m very fond of the Swift A-frame for all hunting and besides I don' t shoot that many rounds at big game.....use other bullets for varminting and targeting....use the A-Frames for hunting only.....they' re a tad spendy and need to be conserved.....but a marvelous bullet.
