I've shot 140s from a 264 WM, extensively. Also shot 180s from a 300 WM extensively.
Recoil isn't even slightly similar, and the 300 was heavier. Same stock, same gun, etc... 300 had a magnum weight 24" barrel, 264 has the lighter 24" sporter.
I agree and that's with a whole bunch of 300 Win Mag's.Even a 7 Rem Mag rocks less,over all.
About all I ever noticed with a 264 is that it "kicks" of course,but the punch is lighter.
The rifles for 264 and 7 Rem Mag do not require that gorilla grip to control common among the 300's.
