[QUOTE="NZ Longranger, post: 502209, member: 14"] MR, I'm only concerned with the correct facts in this debate, and I ain't going anywhere near statements about who can kill what with what etc, etc. You may have been having those discussions with others on this forum, but not me. And I certainly haven't said the 7mmRM is the same as the 300WM. You're quite right about some examples in some manuals being quite different to the norm. That's why I said have a look at several manuals to get an average, because you quoted an example from one manual to begin with. I come back to all else being equal, the 7mmRM will drive the higher BC 180gn Bergers as fast as the 300WM can drive the 210gn Berger. That is a fact whether you want to compare manuals or have a look at the screeds of pressure and velocity data from our range testing of these exact bullets in the same length barrels in many different examples of these two calibers. Loaded to the same 62,500psi pressure we load standard factory brass like Remington, Federal, Winchester, Norma, Nosler etc to, the velocity will be the same. Oehler 43 ballistic laboratory measured pressure and velocity. That is a fact. I have not shot the 180gn CE's in a 300WSM so won't argue with you, but to say in a 2" shorter barrel you'll get 300 fps more than the 7mmRM with the 170gn CE??? I'm struggling with that one but I'll leave it at that! Greg [/QUOTE]
