I have a High Standard "Victor". Bought it used. It was in great shape. Fired it hundreds of times. I mistakenly ran some CCI mini mags through it. Started having failure to feed problems. Gave it a good cleaning. Today was the first chance to get some .22 ammo. American Eagle 45 gr CPRN subsonic at 970 fps. Fired a couple shots then buuuurp 4. Cleared malfunction. Tried again same result including a failure to eject and feed. Put it away. Talked to my smith and he will look at it, but is worried about parts available. I am guessing a worn sear. Any experienced comments would be appreciated.
