barrel turned to 11:58?

The barrel on my 1967 Model 1894 30 30 is turned to 11:58.
How do I get it back to 12:00.
Sorry, but I couldn't think of any different terminology.
I may have turned it some trying to adjust the windage on the front sight by trying to drift it in the dovetail but it was already off the zero mark by 5" left of sight picture.
This is a rifle I bought 20 years ago from a guy that needed $100 to get his truck out of the shop and I haven't shot it until now.
I didn't realize the barrel was turned until I installed a new rear sight that is adjustable for windage and elevation.
I was using a Lazerlyte bore sighting tool to sight it in at home before going to the range to fine tune it when I realized I wouldn't be able to do it with the barrel not square to the chassis.
I don't have any problem with taking it to a gunsmith but I don't seem to be able to get anybody locally to give me a good reference for one other than the retail stores that don't make feel like my business is wanted.
Thanks for any advice.
