Not sure if this should be posted in ammo or here.
The short barreled birdshead shotguns.
Remmy V3 Tac 13 or 870 tac 14 Mossberg Shockwave are the type shotgun I am asking about.
Has anyone reliable done any gel testing with these? Like FBI test.
As cool as they are Im wondering how the short barrel affects velocity spread penetration and in the the case of slugs expansion or performance.
