|I have tried this in my Mossberg .410 Cruiser. 5 pellets of .36 caliber, 70 grain is very potent. Not a 12 gauge with it's accompanying recoil, it is about twice as effective as my .40 S&W Glock.
The lesser 2 1/2 inch with 3 pellets of .36 caliber (9mm caliber) pellets has almost 150% of the power (energy) as my .40 S&W Glock. Still very effective.|
