This is very interesting caliber. 6,5x57 necked down to 6mm/.243 bullet. It would be nice caliber in Mauser for smaller game.
I know there is 6mm Remington which is very similar, but does Halger have any advantages over Remington (shoulder angle)?
Does anyone have any more info about the .244 Halger and rifles made for it? Is there measurements?
