Need help with TC not firing

[mixer]

Hey guys my contender won't fire when i squeeze the trigger,the hammer falls and hits the primer in the shell but it won't set it off,feels like the hammer is not hitting hard enough,i tried a couple different kinds of ammo still doing the same,is there any kind of adjustment i can do to make the hammer hit harder or should i replace the hammer spring or?? i figured someone here could help me figure this out..thanks in advance,mixer

What caliber is it? I've heard 35 Rem barrels can be prone to misfires.

The older Contenders had a double loop hammer spring that was made out of two paralle bent wires of small diameter . THey , TC , replaced that spring with a much larger diameter single spring a few years later. The old springs also seemed to take a set rether easily . So look at your hammer spring if it is the single wire you probably have an ammo problem. Like the other person said , what caliber ? I have a batch of 30 carbine ammo that got a little crimp and will miss fire most of the time becaues they seat against the case mouth. I am sure you can do simular things with a bottle necked case but have not had that occur. Good luck.

The barrel is a 14'' .223 factory contender barrel,i've tried two different tipes of ammo Winchester white box and some wolf i had laying arround and it misfired with both,the hammer spring is a single wire spring,i put 200 rnds thru this barrel and no problems until this past weekend,i'm going to call TC tomarrow and get a new hammer spring coming,any one have any other ideas? Thanks,mixer
