Funny you posted this thread. I've been thinking about posting the same thing. Benjamin is the one I'm currently looking at in .22. But I think you'll find those break barrel rifles are about as loud as something like a standard .22 rifle. I have no experience with the Pre Charged Pneumatic rifles but I've read that they're wicked accurate.
I have a Gamo .17 that was a tack driver at 20 yards but I'm struggling with it this year. I think the cheap scope it came with "flexed" a bit. One thing I did with the Gamo was buy different weight pellets to see which one it shot the best. The ones it didn't like, I sent down range through my older Gamo.
As usual, shot placement is the key. I took out a groundhog at about 15 yards with the Gamo with a head shot. But I'm typically a "head hunter" when it comes to groundhogs anyhow. I'm either gonna knock them down or miss completely. Thankfully I don't miss very often.
