Thread: School me on the 7x57 mauser

They sold their "high velocity" 7mm sporting rifles with the sights regulated for their specific brand of HV 140 grain ammunition, and you were supposed to only buy that. You will see it often saying "for Rigby high velocity rifles" etc. If your sights were for the 175 grain bullet its not going to work for you.

Ok I had a quick look at one of my books (Mauser original Oberndorf sporting rifles) and some early Mausers actually had Rigby .275 as the cartridge stamped on them, anyway I'm going to call my .257 Roberts a .257 Rigby from now on.

WEll, yes, same as any rifle manufacturer, they put their name on them. All of their rifles (or the ones ive seen apart from some early ones) had RIGBY on the top of the receiver, and then under their brand name they put the chambering - which for the 7mm was .275 BORE. (Or .350 or .416 BORE etc.) And then sometimes just HV for high velocity or it written out in full



I still call my .223 a .222 Special. I think it's cooler.
