Hi All,
A friend of mine swung by with this rifle, I don't know a lot about the swiss rifles. I have read that the model k11 and higher will handle the higher pressure GP 11 and commercial 7.5x55 swiss ammo. Before we go out to shoot it we'd like to know if it can handle GP11 ammo. If someone could help identify the model of the rifle from these pictures it would be much appreciated.

Side Shot

Bolt

Sorry for the poor quality of the pictures was in a bit of a rush. I should be able to get more pictures later on if required.

Thanks!
 
That is the sporterized 1889 Schmitt Rubin based on where the locking lugs are on the bolt. Unfortunately it is not sufficiently strong enough to use GP11 (they used GP 90 ammo which was much lower pressures then the GP 11). You also might want to check to see if it was converted to 30-30 as many sporterized ones were.

Thanks for the info! Looks like we're going to have to check the chambering later. Does anyone know a quick/easy way to tell if it's 30-30 vs 7.5x55, if it's not marked?

Check to see if there is a chamber insert. If not, 7.5x53.
You can use 7.5x55 brass as is, and use lighter loads.
I had good results with 35gr H4895 with 178gr Hornady Amax bullets.

I would use 41-42gr of H4895 for the full 7.5x55 GP11 load with the same bullet for the 96/11,1911, K11 and K31 rifles.
