A note, that the 300 Wby has ~20% more recoil energy and a faster recoil velocity than the 300 win mag, which has stout recoil itself. I shot a 7 RM for years before deciding to get a 6.5 PRC for deer and smaller and a 300 PRC for elk/moose and larger. The 7 RM has ~ 40% less recoil than a 300 Wby and is plenty for elk. A 7 PRC may have been a better choice for me, but I do believe 30 cal magnums are better for elk if you can learn to shoot them well.
A 300 Wby has more recoil than a lot of shooters can handle. If you hand load, you may be able to work up an accurate load with less recoil if a muzzle brake, recoil pad and/or adding weight to the rifle doesn't help. You WILL have to rezero when you take the muzzlebrake off before hunting season.
