There were rumors out that Savage and CZ were going to make a 5mm mag since centurion makes the ammo now. I saw a tracker pistol was being made in the caliber. Anyone hear anything on a rifle? This has been going on for a year now. My 592's barrel is gone. I would be better off hurling rocks with a slingshot.
Aguilla is leaking that they have plans to up the velocity since they are at about half the pressure of the original cartridge with today's powders. Claims are 2600-2700 in 30 gr bullet. If that is possible it would put it at 450-485 ft lbs.
