NEW CVA Accura V2 - Intermittent success w/ Percussion caps

[brianmtsinc]

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  )     If so, I will run right now and try out a dozen or so 

Does it make any sense that cleaning out the firing pin could help with the issue I am having ?     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.

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.

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

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.

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 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.

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).

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.

Sounds good to me... just give me a shout...

That is weird that they do not offer a replacement BP

It would be interesting to see one

The rifles are in such high demand right now that is why they are not doing replacement breech plugs right now. I have talked to them many times in the last number of months. When the demand slows they will offer a replacement plug.

A friend of mine had same issue with this gun.  I gave him some RWS 1075 and so far, he hasn't had another misfire. 

[andersonjk4]

Aren't the RWS 1075 caps a #11 sized cap?  I didn't know you could get the new CVA's with a #11 sized nipple.  Maybe I'm confused and they make 1075 in a musket cap size?    

[k88241]

The RWS 1081 and the 1075 seemed to fit the same on the nipple/breech plug that came with his gun.  The Instructions said use the RWS musket caps.  The book did not specify the model number of caps however.

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.
