Frequently Asked Questions

What adapter is needed for Mossberg 500/590 shotguns to reliably fire mini shells?

For reliable cycling of 12ga mini shells in Mossberg 500 and 590 series shotguns, the OPSOL TX Mini-Clip adapter is recommended. This adapter ensures proper feeding and extraction of the shorter shells.

What are the performance characteristics of Challenger 12ga Mini Shells?

Challenger 12ga Mini Shells, including #4 Buckshot and #7.5 Birdshot, achieved velocities around 1200 FPS. The #4 Buckshot demonstrated penetration of 13-14 inches in ballistic gel, suitable for defense.

How does the capacity of mini shells compare to standard shells?

Mini shells significantly increase shotgun capacity. For example, a 14-inch Mossberg 590 SBR can hold 9+1 (10 total) mini shells, whereas it would hold fewer standard-sized shells.

What is the difference in performance between mini buckshot and full-size buckshot?

While mini buckshot offers increased capacity, full-size buckshot, such as 2 3/4 inch 00 buckshot, delivers noticeably more power and energy transfer. Mini shells are a compromise for capacity and manageability.
