SLUGS 2 ?

[BOOM]

!st ? Does a slug leave a barrel rotating to the right like a rifle bullet.Lead slugs do have have lands on them even if the shotgun bore smooth.

2nd ? What would you call a except-able group for slugs at different range distance 50,75 & 100yds

no rotation provided by the "lands"

6-8moa group would be acceptable

here is an excerpt fro the Brenneke website, BTW, Mr. Brenneke IS the father of the modern slug.

He devised a streamlined projectile with a weight-forward design. He added six slanted ribs around the front of the slug, and screwed a felt wad onto its tail. After countless hours of testing, trial and error and modification, in 1898 the first Brenneke slug was introduced. It was an immediate success. Moving the weight to the front of the slug provided stability, preventing the projectile from tumbling in flight. It resulted in accuracy never before achieved from a smoothbore barrel. The ribs, contrary to popular opinion, are not designed to act like rifling in a rifle barrel, but compress to allow the slug to easily pass through a choked shotgun barrel. The massive weight of the projectile—close to 500 grains—resulted in an incredible amount of energy transferred to the target. The Brenneke® Classic Magnum produced today, similar in many ways to the original 1898 model, generates 2460 foot pounds of energy at the muzzle.

so while the ribs "may" impart some spin while in flight, they were NEVER DESIGNED to do so, for those of you interested in gun history the Brenneke story is an interesting one.

There's a GREAT answer. I was relating this to rifle bullet drift, and possibly why shotguns have a POI problem, without the ability to adjust POA using a rear sight. Thank You
