I Progressed from, a .30-06 to, a .270 Weatherby to, a .338 Win Mag then Back again, to, a .270 WSM .
The .270 WSM just "Stomp's" chit with, a 140 Berg Classic hunter @ close to,.. 3,200 FPS ( and NO Belt ).
Reasonable Recoil and even BETTER,.. if Braked ! My Last Rifle was, a T-3 Lite ( NON - Fluted ) SS Tikka Lefty in .270 WSM ( Just gave it to, my grandson during the Summer and he killed, a Buck Antelope with it, in October ).
It's Braked Now and he can Shoot it, All Day Long with,. NO, problem at 14 y/o.
IF, you want, a .30 Magnum go with the .300 WSM, as VERY Accurate Cartridge, JUST Be sure to, put a Brake on, it !
Tikka's, are very Light and the Recoil from, the .300 WSM can Be, fierce,.. off the Bench.
PS; I shoot, a 6.5 Creed, Now, in another, Braked Tikka, 24" SS, Lefty ( It's a Blast with, very, LOW Recoil ! )
