A friend and I went in together on a 200 round (10 boxes) case of, what seems to be, the latest RWS production run of 10.75x68 Mauser ammo. This ammo was bought from a private seller, and I've been told that RWS hasn't made 10.75x68 for possibly 25-30 years. This ammo is all V-Mantel, and is in black and blue boxes with gold lettering. We got a very, very good deal on it, but purchased it primarily with the intention of shooting it all up and using the brass for reloads. However, I am now wondering what type of primers this RWS brass requires. If it is Berden primed, I am inclined to sell my portion of the ammo in order to purchase some boxer primed Horneber brass, as I'd rather not have to deal with berden primers. Does anyone know the answer to this question? Thanks in advance.
