Anyone know off hand? I've one that I've not fired yet, would like to know if I'd be wasting heavy bullets on it, 168 to 175 grain HPBT.

Easy enough to figure out. Put a tight fitting patch on a cleaning rod and run it down the muzzle to just about the chamber. Put a mark on the rod at top dead center or just in front of the front sight. Start pulling the rod out and when the mark comes around to TDC, measure the distance from the mark to the muzzle. If it's 14" it's 1 turn in 14".

Let us know what you find.

1 in 12" for the 2A & 2A1

A thread on the Cast Boolit site might help.

Especially read post #18.
