"What if guns made no noise?"
There are no advantages to the noise of a shotgun (and I am a little jealous of archery).
My life goal was to make shotguns more acceptable to the public. Bird shot is not a hazard to the public but I am concerned that laws will be changed resulting in more restrictions on shooting and hunting. Compared to what I enjoyed as a teenager in Grants Pass, Oregon in the 1950's, hunting and shooting restrictions have been going on for decades. It is likely to get worse in Minnesota as the population increases. But I have solved the problem for myself and my friends. The Quiet Shotgun™ has "opened doors" for us for shooting and hunting opportunities.
"Necessity is the mother of invention". I was losing places to hunt. Landowners are reluctant to allow hunting if the noise would offend neighbors. I invented an advantage that other hunters could not provide-- low noise.
Even though it is legal, I take no satisfaction in shooting when I know someone is likely to be offended. The lake where we hunt ducks and geese is ringed with houses. It is legal to shoot a 10 ga. 3-1/2" shotgun 30 minutes before sunrise on Sunday morning during duck and goose season. If the wind is favorable, I can hear neighbors talking on the other side of the lake. Why would I want to annoy or anger the homeowners on the lake even though it is legal? Once you become proficient with the Quiet Shotgun, it feels good to be considerate of others. (My Browning 10 ga. is in storage.)
