Gentlemen:
Thank you for your replies.
It is good to know that you can safetly shot js ammo in the jrs chamber (with tha apropiate rimless extractor).
The only available cardige here is Selier & Bellot 8x57 Mauser (js) with a FMJ, 190 grains bullet.
Geno: I hope my friend read your reply and convince himself. The rifle-shotgun are very intresting and, I think, in a good price: Merkel 200E, 2 set of barrels, 16 over 16 and 8x57 jrs over 16, scope bases, scope rings and an old weaver 2.5-4 x scope, all in a nice case for $3,500 USD
What do you think?
Best,
