I have a Pac-Lite on my Ruger MKII and I have shot CCI Subsonic several times and it shot good. Today I got a new box and 3 out of 5 cartridges would not feed. I had to push the bolt into battery almost every other time a cartridge was stripped from the magazine. It was like the bullet was a thousandths or so too large for the chamber. Has anyone else had this happen? Thanks everyone, Larry.
