I have an Antique Mauser in 11mm I would like to shoot, I have seen ammo for sale at gunshows and even here on CGN, but I am a bit unsure about the newer stuff. I see quite often people selling that 1950-1960 vintage Dominion stuff but I think that one is loaded with modern smokeless, but these rifles were designed to shoot black powder. But then I know that Dominion produced lots of this ammo, specifically to be used in these rifles. So what to do with this modern Dominion ammo, shoot or not? BTW I do not intend to reload.
