A bit of a strange one I believe. With a clean cylinder, I can load factory ammo rather easily (normal), but after firing 6 rounds, 3 of the cases (always the same 3 positions) are tight and difficult to remove. The ejection "star" SEEMS to be in the correct position and the ejector rod works freely with unfired or no cartridges in the cylinder. This does not occur when shooting 38's - only the longer 357 magnums. As I stated, the cylinder is clean to start. (ultrasonic,chore boy, shooter's choice, and M-Pro all have been used back to back and white patches come out like new after cleaning) Any thoughts?
