I have found a Hatfield .36 and I dont know if my barrel is bent but I have moved the sights way to one side to get anywhere close to center and other than that it doesnt even group very well either .The barrel is slick as brand new so rust isnt the problem .Does any one have so advice?

What powder charge are you using? what size of RB and thickness of patching ?
Might try putting a wad ( cloth or fiber) over the powder, then seat the patched ball.
I had the same problem with mine. Reduced my charge down to 30 gr of 3FFF BP. used a folded up piece of patch over the powder, then I seated the lubed .015 patched .350 round ball.
Good at 25 yds for tree rats.

Just came in from shooting my 36 cal. longrifle, 1 in 48 twist, Green Mountain barrel. . I'm still getting the barrel shot in, but I use a .350 Speer ball, .015" precut pillow ticking patches, which are tight enough that I have to use a short starter, and a fair amount of push to get them seated. My normal load is 30 grains 3f. The gun shoots as good as I can see and hold at 25 yards. At 50, my groups are about 3", and at 100 I can keep all shots on a piece of writing paper, but I have a hard time focusing everything at that distance, so I'm sure the groups would shrink if I could still see well.
You should try different loads and patch thickness before moving the sights too much. Mine shoots to the right with a loose patch, and to the left with tighter patches.

Not terribly uncommon for some of the older barrels to have been bored slightly off center. Not a big problem if the builder is aware of it, they would orient the barrel so the runoff was in the vertical plane. A laser bore sight can help determine if that is the case. Grouping is an issue of finding the right load. I have seen guys shooting rifles with both sights way off center, yet hitting where they aim.
If your lucky you have a fore end that is pushing hard against the barrel due to warpage. If not it could get expensive. The gun builder that built my flint lock spent considerable time in a dark room with a pin light to assure the bore run out was in the vertical plane. He told me that most barrels that he had checked had at least some run out. The longer barrels had more than short ones as would be expected. It the rifle was built without this being done it will get messy if the barrel needs to be milled off and rotated on the breech plug. I hope that your problem can be helped by relieveing the barrel channel! Geo. T.
