The 270 and the 7mm mag are not in the same category.
I find that response somewhat surprising because it seems the 270 and 7 mag are much closer in comparison than a 7 mag and a 300 weatherby mag?
I don't own a magnum of any caliber but if I ever do I don't consider 10 grains of bullet and 100 fps to be not in the same catagory or a categorical step up.
The only magic thing about the 7 mag is that it comes in 7mm and that 7mm number is a very good number to have if one is interested in long range pursuits.
My personal 7 mm preference would be the 7mm Mashburn and though I don't have one I've followed a fella that goes by the name BobinNH threads very closely.
Bobins words on the Mashburn truely have me intrigued and I am very close to taking a step up to a cartrage that truely is in an entirely different catagory than the venerable 270.
