I pulled the hammer back a second time, and it fired just fine. Shots 2-4 all went well. But then, unfortunately, several more episodes of the caps not firing. :dunno: :dunno:
So, what could it be? I stopped on the way home and bought some more caps (German Vorderlader No. 1081) These are the same type I had been shooting (shot over 35 shots my first day without a single fail to fire) and all the store had. I brought it home and shoot 5 caps all were good to go so I thought, problem fixed! :IBCOOL: ... Decided to go back out and try a couple more, and attempt # 6 - no fire! :bash: :bash:
Any ideas or suggestions would be greatly appreciated. Keep in mind - I am not a muzzy guy, nor a rifle guy. The was the first gun I ever cleaned, so maybe I did something wrong the first time I cleaned it?? :dunno:
My hunt starts Saturday, but I head for camp on Wed, so I am basically out of time. Hoping someone has a quick easy answer. :tup:
Thanks in advance! :tup:

I just spent 1.5 hours cleaning it. Should I go try another dozen caps or will that just cost me more cleaning time? :dunno:

This gun was just purchased about 2 months ago - brand new.

Flip the cap over and take a picture of the inside. If it is not black in color from firing, I would look at some new caps.

But like Carp said, it looks like it is striking pretty hard. :dunno:

CVA recommended that I loosen the breech plug and only lightly finger tighten it and try again. Which I did. 5 perfect fires and I thought, problem fixed. He suggest I shoot a few more so, number 6 - good to go! :IBCOOL: ... number 7 - NO FIRE :bash: :bash: number 8 - NO FIRE :bash: :bash:
He suggests that I clean the firing pin again and repeat the above thinking maybe it is blow back :dunno: :dunno: ... and that if I can at least be confident that I can get 5-6 shots before it fouls, I can go hunting with it :dunno: :dunno: Not exactly the answer I was hoping for but I guess I understand the confusion since the firing pin is striking the cap properly :dunno: :dunno:
NOT what I need to be dealing with 3 days before I am scheduled to leave.... :bash: :bash:

Here is a pic. I tried it one more time and it did not fire. :bash: The one on the left, was the misfire. The one on the right, new.
Maybe this will help ?? :dunno:

OK - I am going to throw this out there for what it might be worth....
1. if you were shooting #11 caps I would bet the farm you would not have any problems with ignition!
2. Why.... a cap is not like a primer - punching the middle of the cap will not cause ignition - all you are doing is pushing the ignition material in the primer stack on the nipple. Looking at your examples - I think it is obvious that you hitting the caps very hard causing the almost perfect depression in the middle of the cap. The get a cap to fire you must jamb the ignition material in the cap into a hard object like the rim of the cap. The compression then starts ignition... If the DIAMETER of your firing pin were a little larger than the diameter of the cap you would certainly get ignition.
Knight often has/had the same problem and to solve the problem they are making and shipping a Musket nipple with an offset stack so the hammer/firing pin drives the edge of the cap into the leading edge/top of the nipple stack.
Again will a #11 you would not have this problem because the hammer covers the diameter of the cap.
Here are a couple of pictures to show the offset stack..

Hope some of this makes some sense...

Does it make any sense that cleaning out the firing pin could help with the issue I am having ? :dunno: Don't get me wrong, I will clean it 100 times if I need to, but time is now very short for me and I don't want to waste any if there is a better solution. :tup:
Post by: Sabotloader on September 29, 2014, 11:27:10 AM
Sabotloader - THANK YOU!! Do you know where I can find # 11 caps? And will they fit the same nipple in my CVA? (That might be a dumb question :dunno: :dunno: :bash: :bash:) If so, I will run right now and try out a dozen or so :tup:

And there is the real problem... I do not really know that much about CVA rifles. You can not use the musket nipple for a #11 cap. So does the nipple unscrew from the breech plug? If it does then you need a 6x1 #11 Nipple that fit CVA breech plugs. Then, because the gun is a break open really designed to shoot 209's the firing pin has a very limited reach so you will need a #11 nipple that is about the same length as the musket nipple. from the top of the breech plug back or when the #11 nipple is screwed in to the breech plug it needs to be the same length as the musket nipple when it is screwed in.
This picture shows a variety of nipples available of all different lengths - so I really do not know if you could find the correct length one. I am sure CVA offers only the Musket nipple for your configuration.

Keep the musket cap shaft clean and seat the musket cap HARD with your thumb when loading up.
Musket caps is all you can use on your Accura NW, the nipple and breech plug is all one piece.

I've had 2 RWS musket caps like that, they would not fire no matter what rifle I put them on.

Will do. I am going to go clean it again now and see what happens. Here is what I am using. Should I change brands ?

I also agree with Sabotloader that part of the problem is the size of the firing pin in relation to the size of the musket cap. I think if the firing pin were larger to cover the entire cap that the caps would fire more reliably. My biggest complaint about the new CVA rifles is the fact the nipples are built into the breech plug. One I would really like the option to switch the nipple out for #11 caps and two what happens if the nipple breaks? I have seen ML nipple crack and break and if that happened on a hunt you would be SOL.
But overall I really like the way the rifle handles and the way it shoots (on the few times I could actually get a cap to go off).

I purchased a CVA Accura V2 NW edition way back in March, but just finally got around to shooting it yesterday. I am having the same issue the OP is having. I called CVA this morning and the guy I talked to said that a lot of the early NW edition rifles had weak firing pin springs and that he would ship me a new firing pin assembly right away. Hopefully this helps the problem.

If you are so inclined at the end of the season I would like you to send that BP to me - I bet I or Lehigh
Dave could make it so you had a removable nipple... well maybe I should see a picture of it before I go that far.
I am sure the stronger spring might help but still the nipple post has to act as and anvil and if the hammer does not cover the cap I think it will lead to intermittent problems.

I would be willing work with you this winter after hunting season is over to see if the BP may be modified to accept removable nipples. CVA doesn't currently offer replacement BP's for these new NW legal rifle, but I just sent a rather long email to CVA making asking this question and several other questions regarding the issues with their new line of NW legal rifles. If I can get a replacement BP from CVA then maybe I can get it sent to you for your opinion.

That is weird that they do not offer a replacement BP
It would be interesting to see one

His 1081 caps went off, but it seemed the energy of the cap blew out the 4 slots of the 1081 on the side instead of being concentrated into the breech hole to ignite the load.
Made the switch...so far no more issues.
