Id almost jumped on a good online deal of subsonic s last year, but did a little research first and found they wouldn't cycle anything I owned. Good thing I checked!
Out of curiosity, what do you shoot them in?
A suppressed 10/22. Functioning is not 100% reliable with the Aquilas, but it's marginally better than nuthin. Other brands when I can get them are better, but less available and more expensive. I can shoot on my property inside the city limits without disturbing anyone and don't have to drive an hour or more to go to a range.
