Lock-up problem?

[jpsmith1]

I've got a .35 Rem barrel that OCCASIONALLY misfires.  Less than 1 in 20 rounds. I have posted elsewhere on this board about it when I thought that it was an ammunition problem, but I think that it is a GUN problem.  I can make it misfire by gently closing the barrel.  The hammer cocks, and drops on firing, but never contacts the firing pin.  Is this a lock up problem or what?

Is there a home remedy and should I tackle it a week before a big hunt?  The gun is 100% reliable with a brisk closing action.

I've also been giving thought to having this barrel rechambered to .358 JDJ.  I suppose that Mr, Jones would ensure 100% reliable funcion if I asked him pretty please and included a bigger check, Right?

Are you using a hammer extension?
Many problems such as yours have resulted in the use of them. Especially on G2's and contenders.

No hammer extension.  When this happens, there is NO dent in the primer at all.

  I've had the same problem wit a couple contender frames. I "snap" them closed now as a matter of routine! As for rechambering it to 358JDJ you will get positive ignition. you will also get a ton of recoil! Part of the problem with the 35Rem is the case shape.It is rimless and can fall deeper into the chamber than it should .Due to tolerances you MAY have a fat, deep chamber and your ammo may be on the small side.The 358JDJ is a RIMMED case.Head spacing on the rim helps limit those misfires. The down side of the 358JDJ is a GREAT increase in recoil forces. I'd just get in the habit of "snapping the action closed.

Recoil is a non-issue.  I actually enjoy shooting the .35 rem.  I am looking for a bigger boom, just for the sake of making more noise.  I'm not ready to leap into say a .45-70 without test firing first, but the .35 isn't much to shoot.

I have a reloading book that said the 35 rem in a contender will misfire because the fireing pin will push the shell forward and it has such a small shoulder it will push the shoulder back and not hit the primer hard enough. If that makes sence I had the same problem with mine. Oh this is on factory ammo, it said if you reload dont bump the shoulder back all the way so the shoulder holds the shell and wont move forward.
