Under there is a .256 Gibbs Magnum

Horrific stock and a hint of a side mount at one time. I have asked about such a mount as well as a picture of front sight.

Would make a fine Hill Rifle.

If open sight use is the intention, you might just be able to reshape that butt-stock by removing the saddle-bag.
Might even be enough meat in that fat pistol-grip to contour it properly too....

Excellent bore, nice! I can see a marvelous 'hill rifle' hiding in there somewhere.

Gibbs markings on the nock's form are certainly desirable too!
Any chance a new barrel has been "sleeved" into the breech-end of the original worn-out barrel?
Haven't noticed that little 'step' behind the rear sight base in MS sporters before.

One would certainly think that there is a very nice shaped stock to be whittled out of that monstrosity. It would hold a desire to be as a scoped rifle.

Gibbs markings never detract

:):)

Always a chance of a "sleeving" but I would think it the original. On "military" ones the rear sight sleeve butts up to this "step". Gibbs could well have brought in the barreled actions as x54mm and rechambered to the .256 magnum ???

Here is a picture (thou not so good) of a Westley Richards M1900 with the similar step in contour.

I had found this in my archives, not a great depiction and no text, but was a confirmation on the spec of a ".256 Gibbs Magnum" being none other than the 6.5x55 swede. I think I remember it be being loaded with a 135gr open point @ 2600fps.

The explorer/naturalist Charles Sheldon used one quite extensively in what is now Denali Park Alaska.

A friend who owns a Gibbs on a Mauser action in .256 Gibbs Magnum found the 6.5x55 Swede cases to be too "fat" at the base to chamber in his rifle. He uses 6.5x57 RWS brass, trimmed to 55mm.

I have a Gibbs 256 Magnum sporter rifle on a 1903 (Greek) M/S bbld action.
I think the left wall of the action is marked Steyr 1907.
The Swedish Mauser case base dia seems too large for this one also.
I'd read where the 256 Gibbs Magnum was a shortened 6.5 Swede,,but mine is a x57 case dia at the base. I haven't gotten back to attempting to make cases for it yet. Too many other projects.

A nice rifle, shows use but an excellent bore. An Aldis Bros scope in QD mounts added sometime after it left Gibbs I think as the View proof on the recv'r ring is under the slight over hang of the front scope mt base.
$400 was the price Laying on a gunshow table last spring and no one had wanted her by late in the day on a Saturday. Once in a while you find a good one.

Caprivi:
Thanks for the 'heads-up' on the barrel step v sleeving.
Never stop learning!
Just went and checked my Greek military Mannlicher (had to pull the top-wood off!) to see how this works.

Does this imply that all Gibbs MS sporters were made on converted military barreled actions?
Hard to see whether or not the little spring-detent of the commercial actions is present behind the bolt-handle on the photos above.

I need to pay more attention next time I have a named British maker MS sporter in my hands.

My own examples are both commercial: the 1903 has no Brit proof marks, and the 1910 is Brit marked but no gunmaker's name.
