While thinking about the the best Minie conical-perhaps excessively- for a friend's 1863 Sprinfield replica-the Dixie two piece stock model made by Miroku- I went to the N-SSA small arms board and searched for "Springfiled twist".
I got a topic on slow v. fast twist for CW rifle muskets.
The information there was Springfields were 1-72 and Enfields three bands were 1-78. Enfield Musketoons and two band riles were 1-48.
Interestingly, US Ordnance is supposed to have gone with 1-72 because faster twist resulted in "rotational drift" at long ranges-in excess of 100yds.
I think I have experienced rotational drift at 400yds with my Enfield Musketoon. The bullet seems to shoot to the right even in a dead calm.
It is dead on at 100yds.
Does anyone know more about the concept and compensation for rotational drift?
