Hello,
For modern conical shooting, it seems that most twist rates are 1:28 or thereabouts. Rifles from the Civil War were in the neighborhood of 1:72-something now considered best suited for round balls.
Am I missing something in the definition of conical (obviously plastic sabots weren't used in the 1860's)? Does powder charge have something to do with it? I am thoroughly confused here.
Cheers,
flop
