RE: Slug gun help needed!!!
Two things.....
The high velocity sabots are designed for barrels that have at least a 1x28 twist
Most shotguns (with the exception of the high end guns like Benelli) have a 1x36 twist and its my experience that they do not group exceptionally well no matter what sabots you shoot, and even if you're lucky enough to get them to shoot groups, they are still somewhat inconsistent.
