Firing shot out a rifled barrel?

[jderrick]

I've heard that firing shot out of a modern rifled slug shotgun barrel destroys the pattern, but what about with a slower twist 1-in-66 ML barrel? Or a 1-in-48?

 

I have a friend who has a .60 rifled gun. He tried diffrent methods of firing shot out of it. Nothing really worked and he gave it up.

Once shot begins to twist, it sprays! Not a good thing.

 

I've heard it will lead the bore and the rifling will deform the shot. I have never shot anything but a bore size patch/ball combo from a rifle for those reasons.
