Silencers should be valuable for hunting. An arrow is an example of a good sound level. Carbines (short barreled rifles) have a lot of muzzle blast. Downs'em for 200 yards and scares'em for 2 miles. Stealth can accomplish more, I'd expect.
The other side of that coin is, if I were 30-50 years younger, I'd have a Remington 1180 12 gauge with a 3 1/2" chamber, Poly Choke on the end, 26" barrel, custom fitted stock with a shock absorber, a sling, and a black, Parkerized finish. I'd hand load and test against a patterning board to know exactly what each load and each choke setting delivered. Then, I'd select favorite loads to reload for hunting and all. Also, a 30" slug barrel for long range work. A noisy gun, but it will hunt nearly anything. Maybe an Easter Bunny will bring it????
