conversion from 7 Mag to 300 Mag
Howdy, folks. I'm wondering if any of you educated guys out there can tell me if it's feasible to rebarrel a Model 70 Winchester that is presently a 7 Mag, using a Model 70 300 H and H Magnum barrel. Is this a difficult job? The length doesn't seem to be a problem as far as the magazine. I understand that there are lots of 30's out there that are more economical to shoot. It just seems like an interesting project. Any comments are truly appreciated. Thanks, Barry L.

it is as simple as headspacing the new barrel.
why chase the game when the bullet can get em from here?....

Barry,
While there are certainly no flies on the 7mm Mag., the 300 H&H wreaks of history and great accomplishments. It has just been overshadowed by all of the more recent developments of new cartridges and ballistics. The 300 H&H is a superb cartridge for North American hunting. It is no less economical than the other magnums to load or shoot. Besides, the case has been the basis of untold numbers of wildcats and commercially produced cartridges. If you choose to step up to the 300 Weatherby, you can just fireform the 300 H&H up to size.
As JustC poits out, headspacing is critical. But you may have to set the barrel back to get the sights lined up or timed as it is referred to. The feed will have to be checked also since the 300 H&H is longer and might not line up with the chamber exactly. It may fit in the magazine but you could find a snag in the bottom, rails and feed ramp of the receiver. This is critical for all of your follow up shots. However, being that the H&H has a long taper, I doubt that this will be a big deal.
This is a classic cartridge that also holds long range target records.
Best of luck!0 -
Anything can be done, But at what cost? I am a reloader, I reload all my center fire ammo. the 300 H&H is hard on brass, it streches a lot. their are better choices out their such as the 300 win mag or my faviorit 30 caliber, 300 weatherby, but not in a weatherby rifle, to much bullet jump. Good Luck with your indever.[:p] 0 -
Folks, as pointed out, one reason I would choose to convert this gun from 7 Mag. to 300 H and H is simply because the cartridge does have the history and mistique that H and H tends to bring to mind. I figure I can reload for it and keep the cost of shooting down. I'll bet factory ammo is probably expensive and not too common. Everyone's comments have made me think this is a worthwhile project. Thanks for all the info, guys! Barry 0 -
Barry-
If that cartridge is what you want, go for it.
It's not abnormal to have an intense feeling for a particular round.
I have a love afair with my 1917 Enfield in .375 H+H.
It's my #1 pick for bear and deer.
Obsolete and over-shadowed by newer .375's? - I suppose.
Over-gunned? - Probably.
Made fun of by my hunting partners? - You bet.
Ashamed of my choice? - Not at all.
The few $$$ it'll cost will be worth it!!0
