Ammo types and the semi auto Bren

[browningautorifle]

I was recalling that so many early machine guns had oilers are part of their mechanism.

And it stopped as practice. I wouldn't oil ammo, all our books spoke against oily ammo. Commercial ammo works fine in MGs too, trust me. Ammo with lacquer can have issues in some guns though, as the guns heat up and the lacquer melts and sticks.
