Ammo types and the semi auto Bren

[AmEngRifles]

I am moving on to my MkI Historic Arms Bren next. Have sold the Mk III. I will miss it greatly. I loved the shorter barrel. Just can't find them any more. I did keep my very beautiful Mk I.

Will run the surplus British WWII fodder, some HXP and some MEN, just to confirm once more that this is the right stuff for MY Bren. Then I got a brilliant idea (in MY head anyways), and want to try it out on the PPU and Wolff ammo.

What will happen if I use Rem Oil and spray a light coating over those PPU and Wolff cases before loading and firing? I am curious to find out. Is this a BAD idea?

I was recalling that so many early machine guns had oilers are part of their mechanism. I understand that early guns lacked initial extraction. I know the Bren has a healthy extraction process, by which the bolt pivots on the empty case to break adhesion from the chamber. I am wondering if with this commercial stuff, oiling it would help it break free of what seems like excessive adhesion, leading to those case separations.

Will it hurt anything? It will be a great parlor trick for range time if I can get Wolf and PPU to run in the silly thing...BEAUTIFUL silly thing.
