I've shot a lot of the big mags but only one on game - the .340 Wby. It's not always the answer in terms of weight although mine isn't too heavy nor recoil. Like the others mentioned it takes learnin to shoot but shoot it does. Mine is on a Sucks action put up by shilen and while not a tack driver does under 1.5 inches with its best load but also better than that at 400 yds I might add which is what I regularly practice to. Ross S. long ago wrote it flys as flat a 7mm Rem Mag and hits like a .375. While that's true of more than the .340 now, it certainly still true of the .340. PM me for some details if you wish.
