I have access to a shot timer, 11.5inch sbr, 16 inch ar, shoot house, and a shotgun.
Times to clear the house between the SBR and the 16 were so close to identical as to prove meaningless.
Times between the shotgun and the ARs, made me put away that shotgun for good.
If I have to choose between a gun thats already regulated and registered with the federales, and on that isnt, if in my hands there is zero difference in effectiveness?
I will take the carbine, leave the sbr, and mothball the shotgun.
Just my humble opinion.
Out of interest did the shotgun run behind because of reloads and limited ammo? Thanks for the data points.
