The nastiest minishell slugs on the market! Our 12 gauge minishell slug rounds carry a flathead rifled lead slug. Our minishell slugs cycle reliably in Mossberg model pump action shotguns with the use of our minishell adapter. Comparing to the leading competition, you will see that our minishells contain a larger load and pack a heavier punch.
These minishells are made with a roll crimp and have an overall length of 1.5″. 1.5″ is shorter than all of the other minishells on the market as well. When it comes to increasing carrying capacity of your 12 gauge shotgun, the Mason Munitions minishells reign supreme. To learn more about why our products are the new wave in shotgun defense, check out our write up on the Why Minishell page.
