[QUOTE="GeorgeS, post: 1618994, member: 107925"] I think you're forgetting that the .300 Win Mag was developed 60 years after the .30-06, and the nominal pressures used in turn of the century rifles, with their metallurgy of the time, were pretty conservative. He didn't say that the '06 matched the the .300, he said that you can get pretty close with '06 handloads in a rife built with modern metallurgy, to a .300 off-the-shelf round. There's only about 4,000 psi difference in peak pressure between the two, and if it doesn't flatten the primer of a .300, it won't do so with an '06. Taking it a little hotter in the '06 won't detonate a gun designed to proof at pressures well into the 70,000+ psi range. Hatcher drove some of the early pre-WW1 Springfields well past that without damage. (Not the ones that were built in a hurry during the war, with improper metallurgy) But yes, 25 grains higher case capacity is definitely going to benefit the .300 when both are handloaded. [/QUOTE]
