I want to say 1-20, I'll check mine this weekend.
Ths morning, I found a posting by Doc Highwall on the Castboolits site where he lists the .44 at 1-20, the .357 at 1-18 3/4, and the .45 Colt at 1-16. Believe he has all three.
So if you've not checked yet, spare yourself the trouble and thanks very much.
