This is where there seems to be some confusion. The way you typed this it looks like you believe because the ball from the 35" barrel is traveling at a faster velocity but has a slower twist it is rotating at the same rate as the faster twist barrel out of the 10" barrel with a lower velocity. That is simply not the case.
In actuality the number of twist (or rotations) the ball makes is determined by the twist rate of the rifling and the distance it has has to travel until impact. Velocity, like I said before, determines the amount of time it takes for the ball to get there but is also a factor in stabilizing the ball at a particular twist rate.
This is the reason I posted the FAQ from Dixie Gunworks. It basically says that you can shoot balls accurately (usually) from a fast twist barrel if you lower the charge/velocity. Hence the reason for a fast twist in a pistol.
I don't recall you saying that. Only that it's the way they make them so it must be correct.
I asked a simple question - got an answer from the original poster and came to the correct conclusion whitout your help only your criticizm.
