Falcon, Are you using a #11 cap? I wanted to try Pinnacle in my Knight 85 but didn't know if 11 caps would work.
I shot a lot of Pinnacle 3f out of my Wolverine LK-II and all that had was a #11 cap system and the powder went off fine. Also I shot Pinnacle out of my Traditional rifles with #11 caps and again, no ignition problems...
