My Father was an early 5mm Rem Mag fan. He kept a 591 in the upstairs bathroom, so that he could shoot 'chucks out the window if he saw them in my Mother's apple orchard. I have a 592 and a 580 that has been reworked, but don't care for the 30 grain Centurion ammo, as it isn't as accurate in my two rifles as the original 38 grain Power-Lokt.
