1889 Schmidt-Rubin

[Italian Sporting Goods]

A sporterized Schmidt-Rubin that's been done with such precision, its a clear indication that who ever built this gun was a skilled craftsmen. An interesting piece I thought some people might like to have a look at. Anyone have a theory on what the purpose was for the build? The stock design is very ergonomic and feels surprisingly well balanced and easy to hold on target. Early biathlon rifle maybe?

Are you positive it's chambered in 7.5x55?
Was the 1889 model the one chambered in the different and non existent calibre?

The 1889 is chambered for the 7.5x53.5 GP90 cartridge. Very similar but not quite the same.

Well sounds like we better cast the chamber and find out.

So we cast the chamber, didn't tell us anything. We test fired a 7.5x55 from the firearm. The only change to the brass is in the shoulder. What do you guys think? 7.5x55 or 7.5x53.5?

There's really no way of telling based on the brass alone, The 1889 and the 1911 series would look very similar. The throat area on the 7.5x53.5 GP90 cartridge would be larger as it had the original paper patched heeled bullet. If the barrel appears unchanged i'd suspect it's in it's original caliber. If the bolt stll has it's rearmost locking lugs it's not the greatest idea to fire full power 7.5x55 in them as there is a long distance between the locking lugs and bolt face. A lot of these were converted into 30-30 when brought into North America, not too uncommon to see. A chamber cast with the included throat are would be the most obvious. Also, the earlier barrels were 3 groove, later ones were 4.

When in doubt, load a round and fire.
