the ribs are for filling the gap between the slug and the barrel due to various bore diameters among manufactures as well as choke sizes. the ribs do not invoke spin on the projectile.
Then why do they call them "rifled slugs" and why are the ribs slanted?
Geke, Hate to break it to you, Hoss, but Outdoorsman is right! Those ribs are there justfor laughs!! "Rifled" slugs have been photographed in flight. Little if any, spin resulted from that "rifling" swaged onto the slugs. Actually, slugs cast in a Lyman mould (smooth sides) shot just as well as the "rifled" ones.
At one time, Lyman sold a swaging die for swaging "lands & grooves" onto slugs cast in their moulds. But when after extensive testing they discovered that "unswaged" slugs shot as well as the ones with the lands & grooves, they quit making the swaging die.....
The ribs aren't even needed to go thru a choke-except for on the Brenneke slugs. Then the ribs are needed, because the slug has a solid body.
I was simply asking a question. Notcalling anyone wrong or namessuch as yourself. Try using some manners, makes you look more like a credible source of information, not an "I told you so" child. Maybe smooth slugs do shoot just as good as the "rifled" ones, but I didnt say they spun like a disco ball so a "little" spin may be enough to stabalize a slug just fine. A .45 doesnt spin that much either. Try throwing a football without spiraling it and seehow you fair. I guess we can tell you didnt pass physics class.Wether or not they are designed to spin the slug, they do. Now another purpose may be to fill in a gap or allow for the slug to pass through a choke, if thats the case I learned something new and thanks for informing me. But it's still why they're called rifled slugs.
Deke, you and Stalking Bear arecorrect. I apologize. I was wrong to reply that way. Edit performed....
