Pedersoli Rocky mountain Rifle

sounds like crud in the breech :hmm: If the pan flashes reliably drilling bigger wont help....the flash/heat is not getting to the charge. 3 shots good then issues sure sounds like fouling in the patent breech to me. Try it w/o swabbing between shots using a WET patch over the ball (hoppes patch lube and solvent is the best IMHO). This should clean the barrel fine while seating the PRB and no crud will get by the powder.

Take out the clean out screw and make sure it is drilled cleanly all the way through. One of the Investarms rifles I had wouldn't always fire reliably and when I checked I found a burr left in the hole where it wasn't drilled out completely. Just a thought.

I've used a 22 caliber brush to clean the patent breech. I also pulled the touch hole liner to check for obstruction, but didn't find anything. I think fouling builds up after a few rounds and obstructs the small diameter breech.

It just is a nuisance and yes I’ve experience with them. It adds steps to the cleaning process and introduces another route for misfires. Some appear to be big fans of them hear. :idunno:

Not a "big fan" so much as I just think folks make a bigger deal out of them than necessary. You don't like 'em, don't buy 'em.

I think my advice only applies to cap lock guns. I thought thats what we were talking about in the pecussion gun forum.

I was shooting guns with chambered breeches for over 30 years before I was informed by a freshly minted internet expert they were a problem. The guy’s only muzzleloader was an inline....... Honestly have never had an issue that I would attribute to chambered breeches. There was a guy named Roundball that used to post here all the time about the advantages he found with using them. He even specified that his custom built ”˜retirement’ gun had one. If you push gunk down the barrel when swabbing, don’t completely clean barrel or leave oil in after cleaning you will have problems with any style chamber.

A while back I pulled the breech plug on a TC barrel that at best could been called a sewer pipe. Was getting it ready for a rebore and wanted to see the prize in the gooey center myself. What I found that surprised me was the condition of the chambered breech. It was dark, but no rust or crud. It was in significantly better shape that the actual bore. Tossed it on the bench as a paperweight/conversation piece. I’ll post a photograph of it later.

My mistake. I've not had problems with them on cap locks. I guess it is because it has been so frustrating on the flintlock I have. :surrender:

 

[burlesontom]

No problem kansas Jake. I can't help any with the flint lock. I have one but its NIB and has never been fired. Mine is a Lyman trade 50 cal and they are supposed to be really good guns. But I don't think I will shoot it.

I just like cap locks better. Call me weird. :idunno:

 

[Kansas Jake]

Nothing weird about that. I have both, but have more cap locks and tend to shoot them more. Part of the reason for the more cap locks is I have just run across them for a cheap price and couldn't resist the bargain. I also tend to shoot guns that have been neglected in the gun safe so they don't feel totally unloved. Now, my renewal of interest in muzzleloaders has resulted in most of the unmentionables have become stepchildren.

I only have one flintlock and I have never fired it. Its still unfired and in the box. The other 4 rifles were all bought new or like new and I have a Pedersoli that has been shot by someone else but not me yet.

I used to hit the pawn shops long ago and pick up used BP rifles for cheap. Most were CVA rifles that had been abused, shot but not cleaned or kits done badly. I would buy them, clean them up and in a few cases just rebuild and finish the kits the way they were supposed to be. And then sell them for a profit.

But I don't see BP rifles in pawn shops or gun stores much anymore. I have been told pawn shops don't like to buy them now. I have bought some with rusty barrels but everyone of them cleaned up and had no pitting. But those rusty barrels got me some good deals. I wish I could find a rusty CVA 50 cal and bore the barrel smooth and make a small bore shotgun/roundball shooter sort of like a TC Renegade 56 caliber smooth bore.

There is an issue to consider with CVA guns. The CVA guns have a special breech that has the drum or touch hole threaded into the breech. It is a very much hit or miss prospect to realign the drum after it has been removed. I believe that most people who do the boring out of rifles won't touch a CVA.

 

[burlesontom]

Well I would do the work myself. I would use a 1/2" reamer and bore the barrel then smooth with a slotted rod and emery cloth. No expensive gunsmith needed and no reason to unbreech the firearm.
