Ive never had any trouble with a Contender until today. Bought a new one about a week ago in pistol version with a 30-30 barrel on it. Traded the 30-30 off for a .22 Match barrel as Ive been wantin a good squirell gun and have a stock on the way. Figured today Id fire a few through it just for lack of anything better to do (who needs an excuse to shoot anyway?) First round went in the chamber, cocked it, squeezed the trigger....snap. Ok....bad shell right? Nope...firing pin never met the rim of the .22 shell. Broke it open and tried 3 more time before it actually fired. 2nd round....same thing....3rd round...same thing and the 4th and 5th rounds. Started to get really worried then numbers 6-50 fired off just fine. Never had this happen before....I know it wasnt the shells cause there were no dents in the rims of the first few, then everything seemed to just start working like it should. Anyone else ever experience this before?
