I have modern Winchester M70 in .270 and 7mm Rem Mag. I am kicking myself for not chasing down a 375 H&H in Winchester M70. As it was, I carried one the first day I hunted buffalo, until my rifles caught up with me. It fit as nicely as my 270. Controlled feed, not featherweight! No mushy safety. It's better to look at rifles in hand, than to buy at a distance. I am sure you are not built like me, but good luck. Oh, Weatherby Vanguard 2 ... I got one in 300 win mag, and was amazed at how comfortable it was. Thought that caliber would punish me. Not in that rifle. Cloverleafs from a soft rest. Might try that?
