damaged bore
Black Jaque Janaviac:
I've got a flintlock with a Colerain barrel and I'm thinking I might have damaged the bore through neglegent cleaning practices or gas blow-by.
First I've noticed a change in the load that it likes. I used to shoot just about anything and it would be happy. Now I need at least 110 grains of powder (Swiss 2F is all I've ever used in this gun).
Next, when cleaning I notice a spot right about where the ball would be seated when loaded over 100 grains (my usual hunting load). I can't tell if this spot is a rough spot due to rust, or a slightly loose spot due to erosion.
Are there any clever ways to fix this?
Is it fairly easy to buy a new barrel and just put the pin lugs in the same spot and drop it in? (I didn't build it myself, it is a TVM in-the-white).

I'd take the breech plug out and see what it looks like inside. If its not pitted too bad you could polish it with 0000 steel wool or a scotch brite pad. Use lots of oil.

What patch lube?
Water based lubes used when the gun is to be loaded for awhile will often produce a ring where the wet patch sets in the barre.

Sounds like a descent load to me. ;D

Yes, in particular when they are loaded after shooting and no cleaning and left sit for weeks months!! Suggest wraping the scotch brite or 4/0 wool with a tight fit in the bore and work $#*! out of that area (just that area) before anything else.
Then check with a very tight patch and see if she smooths out. If she does then you can go merryly on down the road. ! Let us know how she goes... :)
