No data on 3.5” shells, but depending on amount of shot i would guess 75+ ft/lbs. Slugs are a whole other story.
Obviously big difference.
As another poster hit on, most of those vids are the dudes in those women’s lives setting them up. Its funny but also dangerous and reinforcing fear of recoil, imho.
The mid tier (2.75” shell) recoil of the 12 guage is 10 TIMES that of the .223...
