Raven is an English Special Forces like the Black Ops in America. Valour is American Army Or the Marine Core. And SAVER is the Rebels.
60- you can then choose to change factions if you like
Size of the projectile
In MAG, all of the factions are technically equal. They all just have different styles and guns. All factions started out the same and none were handicapped. S.V.E.R. is more of a rag-tag rogue group, Valor is much like today's military, and Raven uses advanced technology. Hope this helped.
Case dimensions
Bla kaung mag research!
Size and amount of propellant
Basically the case is all. Same caliber bullet, but the case is shorter in the ultra mag. Its basically just a smaller round, bigger punch.
The 1100 mag shoots 3in. shells, the 1100 standard shoots 2 3/4in. shells.
357 case is @ 1/10 of an inch longer.
Yessir. They should be compatible. the only difference is in the stamping on the back side of the mag, some have said that the follower is different, but I dont know about that.
Biggest physical difference is case size and lack of belt on the RUM
One is a rifle round, the other is a pistol round.
