Hi boys!
I am working on project that is about building a muzzle loading large calibre gun that fires lead bullets. The calibre is 13mm and the length of the gun is about 17cm. I have a question about how the grooving should be done.
1) What twist rate should there be? 3 turn 4 turns?
2) What direction should the grooves turn, right or left?
3) How many grooves should there be, and how wide should they be? For example 12 grooves each groove with the length of 0.4millimetre
4) How deep should the grooves be, for example 0.4millimetre?
And finally what are you basing your answers based on?
Thanks a lot guys.
