I have a 20ga NEF Break Action. It is a cylender bore choke and smooth bore.

My question is whats the point of the rifling of a slug. Does it infact have any affect on the spin of the slug.

I have been told that it is there only for looks and to reduce friction on the barrel.

I would just like to know if it does have an affect.

also I plan on making my own slugs and would like to know if anyone knows the what a good angle the rifling should be at and also the size of the hills and valleys.

Thanks for all the help,

TJ
