Schmidt Reuben K31 Swiss - Page 2

Farmer,

Not so. There was no entity called "Schmidt-Rubin." Schmidt and Rubin were the designers of the original Swiss straight-pull rifles and cartridges, models 1889-1896. Schmidt died in 1898, so he wasn't heavily involved in later rifles.

There was a major re-design of the rifles in 1911. 1911s are stronger than the earlier rifles, but not as strong as the K31. 1911s have a mid-locking action as opposed to the rear-locking action of the earlier rifles.

The K31 came along in (guess when) 1931. Except for being a straight-pull, it shares little with the earlier rifles. K31s lock at the front of the bolt. All three series of rifles have completely different mechanisms.

The rifles were made by a variety of concerns including the Swis national armory. None were called "Schmidt-Rubin."

If you use ammunition intended for a K31 in an earlier rifle, you risk a Kaboom.

I had a Reuben for lunch.

Ok point taken but,

Officially adopted in 1889, the Schmidt-Rubin Model 1889 was the result of several years of testing. In 1882 Eduard Rubin began testing the first small-caliber copper-jacketed bullet which could successfully withstand high velocities. In 1885, this round was combined with Rudolf Schmidt's first straight-pull action.

Thus as the K31 is a more modern design utilizing the S-R straight pull action. Its like a 7mm rem magnum, remington built it and all arms in this style are remingtons.

Ammo for a K-31 is 7.62mm the "89" is 7.5mm and is a much weaker frame this is why you cant use it in older arms, you must use gp90 ammp. The "96" is suitable for GP11 ammo.

^+1 ! Dang Tex, I bought one back a few months, and I absolutely LOVE it. It is truly an accurate sucker!

what do you guys know about markings? Mine has none whatsoever, and the only way I found out what it was is by having a friend who works for INS as afirearms instructor do a search on the federal system (the SN is the only marking it does have) he told me it was a Schmidt Rubin, but he said he's never seen one like it, as mine is heavily modified, there are letter stamps all over it I take to be gunsmith marks. Either way, the dang thing is a tack driver with low recoil and great accuracy.

The K31 action is completely different from the preceeding models. The K31 is the only one that has front locking lugs and a fully supported case head. The only similarity is that all are straight-pull. A cursory examination of the various models will bear this out.

All the cartridges are called 7.5 Swiss, and have exactly the same outside dimensions. Bullet diameter is the same for all. Ammunition loaded for the K31, and subsequent auto rifles, produces much higher pressure than the earlier ammunition. Since it is possible to chamber and fire modern ammunition in the 1889, 1896, and 1911 rifles, caution must be exercised.
