Question on filing the muzzle ???

[smoothshooter]

Thanks
I didn’t know if there was a possibility for the barrel too untwist once filed.
I’m looking forward too testing an old double percussion gun soon…. Don’t even want too mention bending it here…..

The barrel makers would have cut the muzzle and breech AFTER weld-twisting to get the desired length and to square everything up.
Why would it be any different if you did it?

I’m not sure that’s why I ask…..

I can understand the process ….. I think.

Gases escaping on one side the barrel quicker than the other side…Does this create somewhat of a spin/ rotation of the ball or shot?

If not what causes the point of impact too shift when applying this method?

Also does the size of the ball matter? More mass= more filing too get the desired results ?

I’m not wanting too start an argument, but I’m curious as too how this actually works?

A Shot column would be easier I would think compared too say a 1 ounce + mass/ ball…

Please understand, I’m not questioning the results….. but just looking for a more clear understanding of how this actually works.

Friend had one with a slight burr on one side on muzzle. Just enough to feel and it definitely had an effect on accuracy. He used a small sanding drum to touch it up until it couldn't be felt anymore. Made it something more than a demonstration piece
