I have a GPR 50cal. in percussion and wanted to convert it to flintlock. This thing shoots so well I hate to sell it off and just get a GPR flinter. So can it be done ?

Guess the easiest way would be to replace the lock with a Lymna flint lock and replace the percussion breech plug with a flint one. Else you would have to mill off the which-a-ma-callit where the nipple is located. You might or might not have to relocate the passage to get the touchhole to line up properly to the lock. Nothinng insurmountable, but could be a chore.

Why would I have to replace the breech plug

It would also be nice to find a used barrel to have bored out for a smoothy. Any suggestions ? What cal. barrel would I need to make a 20ga./62cal. out of it ?

I think you just answered yourself.....

Because the GPR percussion breechplug will not work in a flinter. If I remember correctly, (50-50 chance) you do not have a drum and nipple but you do have a patent breech. Therefore you will need to change the breechplug. Or mill it off. If it has a drum/nipple arrangement, then I stand corrected. Should just be able to put a liner in and go for it.

I bet you would be time and money ahead and happier with a whole nuther gun in flintlock to go with the fine shooting cap gun you have. A feller can't have too many toys I don't reckon. :-)

Let me `splain a little better. I was thinking about buying a used Lyman barrel then have it bored out to 20ga/62cal. If Lyman makes such a barrel i`m in there but i`m not aware of them making one. So I was thinking about having one bored but i`m not sure if I need say a 50cal. or 54cal. etc.

I`ll go along with that but my reasoning for all this is I already have this rifle shooting excellent and really have no need for two of the same caliber so I was hoping to turn my tack driver into a flinter, keep my 50cal. barrel and have a 20ga. smoothy for it also. Good idea huh!!!!!!!!!

If you take the barrel off of the stock you may not have a tack driver with a new barrel. As stated for what you would pay to have a barrel reamed and made to fit properly you could probably get a smoothbore or make one.
30 years ago we used to buy a Dixie flintlock, find an old gunstock and an old cartridge shotgun barrel. Then , tap the barrel and make a breechplug and tang, fasten it to the stock and Bobs your Uncle, you have a flintlock smoothbore. Isn't pretty but it worked well.

still do that today . if you read bill brockways , recreating the SXS shotgun , thats what he does .
the little NW trade gun i built for magpie a few years back . yep center fire barrel
back when i built my first muzzleloader it was a old military 03A3.
breeched the barrel. hed spaced the bolt .... and bobs your uncle .
but i would say , you better know what your doing or you can end up with an issue

If I were you, I'd just buy a replacement Lyman Flintlock, and a replacement Lyman barrel. This way, you can have the best of both worlds, with the same stock.

We can't all be wrong!! More guns is better!!:-) Besides, it saves time doing all that barrel swapping back and forth when you can just pick up a whole nuther gun and go play!! :-)
-
The only savings is the stock and trigger! I am voting for a whole new flintlock. You can get it in 54 cal and possibly have it re bored to 28 ga pretty easily. Maybe ask a good barrel person about 20 ga.
