I don't think the cycling is the main issue. The description says that they might not clear the barrel and firing a second round would cause major damage. After looking through a bunch of feedback on these rounds, it sounds like a LOT of people have no problems firing them through their rifles. Although I didn't see anything regarding the 15-22 specifically. I might have to be a guinea pig and pick up a box. Quieter than an airgun they say!
i think you will need a suppressor to get that affect.
