How far away will you most likely be when you attempt to shoot the deer ?
511 lbs is at the muzzle with that ammo. Unless your hand loading with the 45 Long Colt, I wouldn't hunt with it ! There's not enough energy transfer to take a deer with one shot. Your better off with a 44 Mag or 454 Casull. After 25 yards the bullet energy starts to drop a lot faster. You want something that's going to hit with a muzzle energy of at least 500 lbs at contact with the target.
Remington UMC line 44 Magnum 180 grain has a muzzle velocity of 1610 fps and a muzzle energy of 1036. At 50 yards it's at 745, and at 100 yards 551. This would be optimum ! The 45 Long Colt unless hand loaded just don't have it.
I would hate to see you have to put 3 or 4 shots into your deer.
