CL: Just a suggestion but that M70 06 action will convert nicely to a 375H&H,and a light 23" barrel goes with the 375H&H like peaches and cream.I have one on a pre 64 action that weighs 8 pounds on the nose, is very accurate and easy to shoot.
There is no law that says a 375H&H has to weigh 10 pounds...
So, there is no need to change cartridges if you can't find a good reason to do so, and it is also no trick to load the old Holland round to 2300 or so with a 270-300 gr bullet,in which case there is little to choose between it and a 9.3x62,and the extra reserve of power is there if you need it.
Plus you can still get factory ammo anywhere.
BTW Federal Premium with the 300 gr Nosler Partition that I have chronographed did about 2400.
