Nope. If I shoot something with a gun, I plan on it being permanent. A couple stories about less lethal shotgun rounds- 1- We somehow ended up with some rubber slugs on an ammo resupply pallet overseas. No idea why, since we didn't ask for them (sometimes I think "they" just randomly threw things on pallets that were just sitting around- like the rifle smoke grenades we got on the same trip). Anyhow, we decided to mess with these rubber slugs. I took a shot at a E type (20 x 40) sillouette center mass at 25 yards with a Mossberg 590. Hit it square in the forehead. Tried again at the same aiming point, and completely missed the whole thing. Team leader tried next, and hit the tire wall. The slug bounced back and hit him in the foot. We decided that there was some serious accuracy issues with these things, so we quit firing them and disposed of them next demo shot.
On another deployment, I found some 40MM rounds (for the M203/M79/M320 GL) that were also a rubber projectile, with the consistency of a nerf football. They were of German origin. I never fired one at anyone- everyone I fired a GL at that trip got H.E.- but I always wondered what it would look like if someone got hit by one.
After I retired and was working at a friend's gun shop for a while, someone came in asking about less lethal shotgun rounds (which we didn't sell). Seems he had a black bear snooping around his home, that he didn't want there, but he didn't want to kill it either, so he figured he would just smack it with a rubber slug or shot. I convinced him that hurting/enraging that critter may not be the best idea, and that he would be better off finding a different method to scare it off, like a air horn.
