Re: Help finding out barrel twist
Clean it and after you get a patch going through it smoothly use a tight patch on a jag with a rod with a ball bearing handle. insert the rod a few inches into the bore. Mark the rod, with a pencil or sharpie by the handle on top and also at a point like at the beginning of the action. Now push the rod allowing it to rotate with the rifling and watch the top mark to make one full turn. Then put a second mark at the place you picked like the beginning of the action as soon as it has made one full turn. Remove the rod and measure between the action marks to find how many inches it traveled durring one full turn. I would do it 3 or 4 time to be accurate as possible.
