Great list Sendit
Not to mention.
loud shooting is uncivilized.
Too add
(1.) With a good can there is no muzzle blast therefore no directional signal, only a bullet crack and it will appear to come from where ever it passes closest to you if your in the field. Lesser cans will have a significant reduction. Subs = a quiet mouse fart.
(2.) Recoil is spread out over a longer duration there for it feels like a push not a kick.
(3.) Kids and wife can take naps while i shoot HP rifles off of deck on my 200 yard range.
(4.) Neighbors wonder why I am hammering on steel, (that is all they hear), think I am in construction. LOL
(5.) Kids will shoot a 300 BLK SUBS, 22LR or even 223 all day and not be scared of it. Great way to introduce kids to shooting.
(6.) Coyotes can be coming into a stand 500 yards apart or 5 min apart and don't know their predecessor has deceased already. Coyotes where I hunt are shot at a lot, they know what shooting is and get out fast when a shot is heard anywhere with in a mile of them.
Way too many to list.
