Try a tight cleaning patch on a jag. Mark a thin mark parallel to the axis of your ramrod. Make it near the end your hand will hold to ram the rod. Slowly,and with a light touch to allow it to rotate with the rifling, ram the rod down the bore and notice how far around the rod the mark rotates. When finished ramming, mark the rod where it enters the bore. Measure the distance from that second mark to the end of the jag. That's the effective barrel length that you measured. Now, take the fraction of rotation that your first mark made "around" the rod (1/4, 1/3,1/2 etc). Take the effective barrel length you just measured, and divide it by the fraction that the rod rotated. The number you get is how many inches your rifle takes to make one twist rotation. If you ram the rod down 24", and the mark rotates halfway (.5) around from where it started, then your equation is 24"/.5=48. Your rifle is a 1-48" twist. That's probably the most likely TC twist,though you may also find a 1-66" or a 1-28".
