Rate of twist in ball revolver

[ian45662]

Would anyone happen to know off hand what the rate of twist tom ball used in the guns that he tuned up?

Bobby Hoyt made the barrels for Tom. I believe the 44's were 1 in 13 twist.

Scratching head......mine is gain twist so I reckon it starts slow at my end and faster at the other so how do you tell what it is?
