Difference Between Slug and Pellet Magazines
The primary difference between slug magazines and pellet magazines lies in the hole diameter.
A slug magazine features tighter hole tolerances, specifically designed to hold slugs securely in place. This prevents the slug from shifting during feeding and ensures stable, consistent alignment when entering the rifle probe.
A pellet magazine, on the other hand, has a larger hole diameter to accommodate pellets. Because of this larger diameter, pellets cannot be used in a slug magazine.
While slugs can be used in a pellet magazine, they may shift or sit loosely—similar to a standard magazine—which can affect feeding consistency and accuracy.
Please note:
You may be unable to fit our magazines to your gun if you are using an aftermarket non-standard or non-factory original part, such as Brass Transfer Port. Before purchasing this magazine, please make sure all your rifle parts are original. We do not accept returns if magazines get dented or scratched for that reason.

Very impressive. Well machined. Smooth rotation. Holds Pellets without tilting. I have not tried an extensive variety of pellets and slugs yet. However so far it is in a totally different league than the FX standard high capacity magazine.
