7.5x55 swiss k31

[saitek]

does any body know if you can fire factory loaded parvi partizan ammo in a k31so you can fire form the brass . or do you have to size the new brass with k31 dies first ,i know there is a chamber size difference between regular 7.5x55 like in a swiss 1911 and the k31 .but i just dont know about the loaded parvi partizan they just started selling . i know grafs is selling it as loaded ammo and just boxer brass

That would be Prvi Partizan, not Parvi.

Yes, it's fine in a K31 and the brass is quite good.

Also a buck cheaper here http://www.ammunitiontogo.com/index.php/cName/rifle-ammo-75x55-swiss
but check the total with the shipping costs.

I've fired plenty through my K31. It's hard to beat Prvi ammo for Euro milsurp calibers. Brass is pretty good too.

The chamber of the 1911 rifle is tighter than that of the K31, any commercial ammunition that follows the GP11 dimensions will fit the K31 and will also work fine in the 1911. The difference for the reloader is that US sizing dies for the 7.5x55 originally reduced the case dimensions to fit the 1911 rifle chamber, which worked the brass excessively for loads to be used in the K31. Redding dies in this caliber can be ordered for the K31 dimensions, which means your cases will last a lot longer. Cases for the K31 do not have to be fire formed, the dimension difference is in the diameter at the shoulder, which does not affect accuracy.
Your Prvi ammunition should be fine to use as it comes from the factory.
