I finally cleaned it up enough to shoot. My mag doesn't seem to want to take the fifth round very well.The rim of the cartridge won't sit against the back or side of the mag leaving the bullet slightly askew compared to the others.I think the rivet is slightly too high in the mag not allowing the bullet to go down far enough to properly load against the walls of the mag. Anybody else have the same experience ? All said after I set the regulator to 1.5 it shoots well at -28 celcius,no jams,lots of noise and smiles.
