I shoot magnums as well and have not found them dificult to shoot one bit either and I am about to buy that 338 Ultra mag but I still stand 100% behind my statements that a .270 win is a very capeable elk rifle and would have absolutely no reservation shooting at the largest bull elk at 300 yards or so.
Basically if a .270 wouldn't have killed it then it is very unlikely that an ultra mag would have done any better. Yes a 375, or 416 will shoot through its butt to the lungs but I aint taking that shot no matter what gun I am toting around in the mountains. Some people like to take the "Texas heart shot" but I don't and won't.
BTW, about how many times a year does this topic come up around here?
