Home Forums Hunting & Shooting Ask The Gunwriters Who developed the 7mm Remington Magnum?

"Better than a 7x57 Mauser" I have never seen that in print. Need to Digest that one.

Where's Ingwe?

DMB,

I think your case capacity numbers are off-kilter. The 7mm Rem. Mag runs about 83-84g.

The Mashburn is 90 gr. +/- on my .300 Win. based cases. 7 mm Weatherby is about 86-87 gr.

Thank God, I thought I had done it.

Here's what John T. Amber wrote in Gun Digest 1963, covering the new 7mm Rem Magnum, and also the new Remington 700:

"The biggest event of 1962, certainly as far as big game interest is concerned, was the bringing forth of two complementary items by Remington. These were the Model 700 rifles and the 7mm Magnum cartridge, both of which, by all accounts, are living up to the advance billing.

.....

"Big capacity 7mm wildcats have been the choice of numerous big game hunters for many years, going back to the old 276 and 280 Dubiels, then on to the 7mm Ackley, the 7mm-06, the 285 Luft, the 7mm Mashburn Magnum and others. The 7mm Mashburn has long been a top favorite of Warren Page, for example, who has used it with every success in all parts of the world, and on just about everything shootable except the largest of big game....

.....

Page, I feel sure, may be considered responsible in good part for the emergence of Remington's belted case magnum, along with Remington's Mike Walker. Mike is also an enthusiast for the 7mm, be it the new one or not....

......

Les Bowman of Cody, Wyo. who is as much of a rifle crank as he is a big game outfitter, has been working with prototypes of the new Remington 700 since a year ago or so, and recently with a production rifle. He has, of course, amassed a lot of reloading dope,..."

Don't know if that is definitive, but at least, that was the contemporary view of credit at the time.

I've shot my 7x57 exclusively since 1983, so I agree!

DMB: To lend perpsective to your good post on those older 7's,with today's powders in 24" barrels, the Mashburn is pretty much 3250 or so with the 160 gr bullets with pressures that "appear" normal,or at least not excessive;and the 175 is easily doing 305-3075 without "leaning" on it..

So far, H1000 and Retumbo are providing the fuel for these velocities.

This from two rifles we have back here,and both with 24" Kriegers.
