April 2019 Monthly Postal Match Results

Well, the only other two things I can thing of; 1. are your caps stored where they're drawing moister? 2. Perhaps your lock's main-spring is getting weak?

I guess there is one other thing - you might try and take some emery cloth and run it around the nipple cone.  Perhaps the nipple cone is to large where the cap base bottoms out on that cone?

Yes those matches were all off-hand

Sharpstick,

Check your nipple.  when it becomes mushroomed from use the cap will not seat all the way down.  The first hammer fall only drives it down onto the nipple and the second hammer fall will fire the cap.  This may be your problem.

I see this often on the firing line at rendezvous shoots.  Two quick fixes are:  try a larger cap.  Remington caps are a little larger than CCI.  Replace the nipple.  I always have a spare nipple in the patch box.  The damaged nipple can be filed down by rotating it in your drill while filing it.

If that doesn't do the trick try a new tin of caps.  It's possible the caps are damaged but I doubt it.  A weak mainspring would be the last possibility I would suspect.

prarie dog,
I haven't had time to look at the nipple closely yet, but I think you've pointed me in the right direction - a mushroomed nipple. And I like the idea of using the drill to file the nipple down a little.
Thanks

I replaced the original a while back and I noticed the newer one may be slightly larger in diameter than the original such that the caps don't seem to fit as well.

It sounds like this is definitely your problem.  The slightly larger nipple acts the same as if it were mushroomed.  I had the same problem many years ago, which is one reason I shoot flinters!   

And, as Steve said, chuck the nipple in a drill and run it against a piece of sandpaper.  Be sure to check it frequently with a cap to make sure you don't take too much off!  Let us know how you do, inquiring minds need to know.
