I vote the 460, Got an MGM Barrel with a brake even with heavy loads I don't think recoil unbearable, and I have the versatility of using other rounds to down size the load. Have consistently shot an inch and half groups at 100 using Muzzle loader Bullets (Hornady SS T's) While you won't find a load in the books for this bullet. I started out with 38.0 grain of 2400, settled on 39.0 grains. Have yet to conograph the loads to see the speed. Just got it (460) before pistol season in Delaware as all one can use is straight wall cases. Killed a Deer with it made on h--- of a exit wound. I have loaded other powder combination for this Bullet starting with the lowest I could find and will approach maximum with extreme caution, Quit when the slightest sign of pressure is seen, This information is not for everybody it is what I have found out so far. I do not recommend a newby at reloading to try this, Remember it is you pulling the trigger when it doubt throw out. Lou
