Buy yourself the rifled/cantilever barrel, but make sure to use either 3" or 3.5" shells when using slugs.





Q:
Why can't I shoot 2-3/4" slugs through my 3-1/2" chambered slug gun?







A:
Firing a 2-3/4" slug in a 3-1/2" chamber is not recommended because of the length of the jump the slug makes between the end of a 2-3/4" case and the front end of a 3-1/2" chamber. This can cause misalignment of the sabot on the slug, thus causing a serious pressure problem as well as poor accuracy. Slugs are NOT LIKE SHOT SHELLS where a shorter shell can be safely fired in a longer chamber with no ill effects. The bottom line is you should use a shell with a minimum case length of 3" (ideally 3-1/2") in any 3-1/2" chambered rifled barrel for best accuracy. THE CASE LENGTH SHOULD MATCH THE CHAMBER LENGTH WHEN IT COMES TO SLUGS.
