I use to shoot a LOT of round balls in a 30 carbine, built like my long barreled 45 Auto Rim, and I believe it was actually quieter than a mouse fart! Out to 30 to 40 yards or so, stray cats had absolutely nothing good to say about it!
I have also chambered several 22 Hornet in my barrel liners, and loaded with match grade .22 caliber pellets, once you have the brass, you can load a hundred rounds for about the same cost as good 22 long rifle ammo, and for squirrel and rabbits, there good out to around 50 yards.
