I think the 7.5mm MAS ammo is useless. Most if not all European ammo is Berdan primed and not reloadable by conventional means. I could be wrong, the best way to find out would be to pull the bullet off of one round and check for primer holes. If there are two, it is Berdan primed and useless. The brass is only good as recycing scrap if you can deactivate the primers (good luck as they are probably mercuric). The bullets, if pulled carefully, can still be used though GI1. Just my $0.02 worth.I have been told that the ammo is bad by numerous people. I have not tried to shoot the 7,5 ammo yet. I have been told to try it in the MAS 36 and not the MAS 49 series because of various pressure problems. It should be good to go in the bolt action, but expect hang fires.
I do know for a fact that the 8mm Lebel would have to be reloaded. I did not know this ammo was primed that way. I assumed it was like the PRVI. I know realize I incorrect as that is not surplus or loaded anywhere close to the original specifications. Almost a whole different cartilage. (you can't load the 8mm Lebel into the 1886 pattern rifle tube because it will ignite the PRVI or commercial made ammo - - the primer cap is not doubled & the back of the round is layered differently)
I just don't know what to do now.
