Well, the reason I sold my fancy MKII was to go to a less tempermental launch platform for the .22 - a revolver. My 4" 617 has been very accomodating, ammo-wise... cheap works! Here is an early picture of my 617 before it got Ahrends retro targets and a green HiViz front sight:
Cheap rules... like my now gone from WallyWorld favorite - $16/550 Federal #750 36gr clad HP. When Federal catches up, they may be back - watch those folks! The odd 'flier' provides 'Mulligan' claims, too. In all honesty, my 617 loves Fed Game Shok - only at Academy these days - $9.59/50. It really likes the cheap stuff - ween 'em on the cheap stuff!
