what are you shooting it out of?Ok. Got the sparrow 22 home today. Ready to try it out. What is my best option for ammo that will be the quietest based on your experience?
bolt gun or non semi automatic? most quiet is CCI Quiet. but it won't cycle semi automatic pistols/rifles
semi automatic rifle or pistol? if you can find it, CCI Quiet Semi
less than a 4.5" barrel? CCI standard velocity will stay sub sonic. Longer than a 4.5" barrel? it will still stay subsonic most of the time but it's definitely much louder compared to the CCI Quiet stuff (it's around 700-750fps vs 1050 for the CCI standard).
If it's shorter than 4.5" barrel, most of the bulk 22lr ammo will stay subsonic except things specifically high velocity. My favorite for most shooting where I'm not that concerned about sound but still want to shoot a lot and have decent accuracy is the Federal Auto Match bulk boxes (325 round for about $17 at Walmart).
