Thanks for all the advice guys. I don't need super accuracy and I'm not in the business of making noise. I just need to trade up from a hand-me-down Stevens bolt action .22LR that has no sights (got it that way). Nailed one ground hog with it with one shot at 30 yards and chalk that up to luck. I like the 10-22 suggestion, but would need to add an adjustable stock (my son has longer arms than I have) and perhaps a scope (old eyes) later after I get the hang of it. Will start checking some local gun shops (less the one that is always overpriced in Frederick) and see if any other used recommendations are available. I am not averse to using the internet for new guns, but am leery of getting a used one sight unseen. I was hoping someone had some experience with either the Mossberg (always been impressed with their practicality and affordability) or the USSG (a real unknown for me), but I'm not hung up on them. I'll see what I can find. Thanks again for your time and advice.
Don't sweat ordering over the net. I've never gotten burned. You get pictures. Just check the reviews of the seller. I'd look at gunbroker.com. You just need to factor in the shipping and transfer fee. Also check out the major online dealers like Basspro, Cabelas, Gander Mountain, Brownells etc. This time of year, end of the hunting season and pre-Christmas there are always sales.
I wouldn't worry about the stock issue on a 10/22 either. I bought mine when I was ten. I'm a bit taller now.

It shot fine for me then and it still shoots fine. Its like an M-1 carbine. You might, this time of year find a package deal on one with a cheap 4x scope. If its halfway decent (and most I've seen are) its enough to get you started. If you want better glass you can get it later. Get the gun first, then figure out what if anything, you want to do to it later. Unless of course you find a sweet deal on a used one with the bells and whistles you want. I wouldn't hold my breath on that though. The 10/22 is such a standard that it holds its resale value. Rastus' suggestion on the Remmy is where you might find a steal. Still, as a platform that just keeps working and you can do anything with, I like the 10/22.
Good luck.
