My M70 pf 24" 300 Win Mag shoots a max loaded 180 NPT with good accuracy using RL-22 just fine at 3110fps seated to 3.34" (because of the mag block in the action), yet my M700ss has a 3.6" box but a tighter chamber and will not even begin to tolerate the same load. Ended up using IMR 4350 and 180 gr NPT's with it avg 2995 fps . Can't see a difference on how dead the animals are with either load. I mean you know they were just as dead as you can get them. Everything shot with my 308 Norma gets dead too. Damn it all for there not being a provision in determining the degree of deadness. Oh besides that you can buy 300 Win Mag ammo just about anywhere ammo is sold. Magnum Man
MM/RD: Far as I'm concerned, you can take most all the belted and non belted 300 magnums, toss them all in a bag,shake it up, reach in and grab one....and end up about the same place. Things like a 30/378 excepted. But cripes I have never seen one of those used by anybody.
Funny that you should mention that.
A good friend acquired a .30/378 and worked up a load for an out of state trip this fall. The guy is an experienced reloader and hunter. After trying about everything to make the .30/378 shoot he backed it down to about 3050 fps and got very good accuracy. He did get his elk but could have taken a smaller .300 out of his safe and done just as well ..........
Yeah, why burn just 70-80 gr. powder when you can burn 110-120?
