Hey all, I only recently picked up my 15-22 and decided I'd like to shoot it. I made it out to my buddies very large piece of land and had a go with the Aguila Super Colibri.
Obviously the bullets don't have much range or accuracy, but I was having a blast shooting, even while cycling each round manually.
The Super Colibri was insanely quiet, so much so that no ear protection was even remotely needed, and is certainly more quiet than a pellet gun.
Sorry for the lack of details, just excited that I got to shoot the rifle, and even more so that these rounds are quiet enough to not need the muffs etc. Just plain fun!
