Thread: How to make my .22 quieter

So I am finding my .22 louder than I expected. I thought you could get them really quiet using subsonics and a suppressor, but I didn't really know what to expect having never used actual firearms before.
I'm using CCI subsonics. I bought a cheap $45 no-name suppressor off the local Elio's gunshop, because the fella said it was good and recommended it, said other customers rated it highly. I said I was prepared to pay for the DPT one but said i'd try the cheapo one.
This new suppressor makes it pretty quiet if you shoot straight into the ground, but if I shoot a target 30m away it makes a pretty decent crack still, loud enough to alarm my chooks 50m away, echo off the trees 100m away, and alert my family in the house with closed windows. It certainly would alert any nearby rabbits to my presence.
Are my subsonics actually going supersonic? What am I doing wrong? Or were my expectations unrealistic?
Or should I have paid for the more expensive suppressor...
