I have an old cva derringer in .45 cal. there is something stuck in the breech area and is obsturucting the barrel. I got it this way. is there some where I might be able to get a replacement barrel? maybe a little longer too to have a little more accuracy?

Help Support Muzzleloading Forum:
You can probably remove the obstruction yourself though. You can thread a grease gun to the nipple hole and pump grease under pressure to push it out. Even compressed air might work. Pour oil through the nipple hole and let it sit a while before you start though, just to make sure there's no live powder in there. If it's a stuck ball, you can get a ball puller for only a couple bucks most anywhere that sells muzzleloading supplies.
CVA may have some spare parts left for the gun so it might be worth a call if you end up needing to replace the barrel. I doubt you'll find a longer one that will fit unless you have it custom made.

Perhaps heating the barrel to get it to expand away from the obstruction, then applying grease under pressure, or compressed air? If something was poured in to render the barrel inert, it probably made it's way into the nipple area and won't be removeable. Good luck and let us know what you find.
Maybe pull the breechplug and knock out whatever is in there?
Never pulled a breechplug. What all is involved in doing that? and how hard will it be to line the flats back up once I go to put it back together? Bought a really nice one for $30 and let my son talk me out of it. But I think that I ahve gotten more enjoyment out of wathing him shoot it than me shooting it. He swears that he will be out shooting me with it.

Pulling the breech plug might be hard on the CVA, I had one (not the derringer another model) and I swear the vent liner's sleeve was locking in the breech. Not the vent liner itself but a sleeve the liner went into. I gave up on when the tang started to twist out of shape.
1) Attempt to remove obstruction with a ball puller - drill a small (1/8") into the material as a starter hole for the ball puller. This is your best bet for removing the material. If the puller will not thread into the material, then:
2) Remove the nipple and thread a drain kit into the nipple hole. The kit consists of a special nipple and length of hose; they are available from Deer Creek Products 765-525-6181. You will need the kit with the M6x1 thread, AC-1631. It's about $5 plus shipping. Once the kit is in place you can pressurize the hose any number of ways. This is not a high probability of success, nowever. If it doesn't work, then:
3) Deer Creek products may be able to sell you a new barrel. CVA no longer maintains parts for those old kits; they referred me to Deer Creek when I needed a replacement lock for a CVA kit I built in the 70's, and they did have what I needed. You will probably have to finish the metal, however.
I would not try to remove the breech plug as that takes some pretty heavy duty tools and experience. Heat is also not recommended as overheating the barrel could damage it's material properties significantly. You might fool around with the breech plug or heat once you know you can get a new barrel.

Alos, i would not use heat as you don't know if there is a powder charge in there too.
I've fired mine several times. Not as much fun as the Colonial or Hawken versions because I like to actually hit what I'm aiming at. There is no hope with this gun at any range over about 6 feet. But then, how far is it across a poker table?
Longer barrel is not an option - the barrel tang will not fit. I suppose you could relocate the tang, but then you'd have a barrel with a notch showing on the underside and have to go through the trouble of cutting a new mount on the barrel. Why ruin a perfectly good barrel? Just buy another gun.

I wouldn't use heat or try to shoot it out. If that is a ball and charge in there, and they used smokeless powder, you might wind up with some serious injuries. Try screwing a ball puller into the material and seeing if that works. If it doesn't do the job you might get some material on the screw that will give you an idea as to what is in there.

Have no idea Plink... just the way it came and I've never seen others to compare it to. Maybe they offered them in kit form and somebody added their own piece of wood?
One of those impulse buys I guess... don't know why I even bought it or why I haven't resold it. I have a couple of rifles and a Siber pistol in 45 caliber that I do shoot, but somehow never got around to trying this one out.

If it is a loaded ball/slug stuck in there the grease gun will force it out.
Got the barrel clear last night, looks like they put in grease to store it and it just hardened up over time. I have had it for about a year now and this is the first time that I have fooled with it. It is something to tinker with on these cold new jersey winter evening. I am in the process of refinishing the stock and barrelnow, have the before pics and will post the after them when i am finished. thanks for all ya'lls help and info.
:bow: I picked one up off the table one Sunday Open-House at my gun club---for $35. It wasn't intoo good a shape---the finish on the stock looked like someone dipped into a can of something, the barrel was rusted inside and out. So I refinished it and polished everything up, cleaned the barrel inside and out---I now have a real nice looking little shooter for 6' targets. The trigger dingle-dangles but other than that--I am quite happy withit as I am sure you will be with yours. :v :hatsoff:
I am in the process of trying to get the trigger to be a little amoother. took it apart and polished everything and noticed that I need to remove some wood in side because some of the lock parts are hitting the wood. should do a little better after removing the wood. would like to take out the coil spring but I'm scared that I can't get it back on. Will see how it is afer removing the wood. Then I will take a look at my sons to see if it is hitting wood too, and see if i can make it a little better. But the way he shoots I might not try to fix it that way I have a little edge over him shooting.
