I have an old Browning Citori O/U I bought used for $375 about 10 yrs ago. I bought it from a retired LEO. He said he was getting too old to shoot skeet.
I got it "Pro Ported" and had the sights changed. Its not the prettiest gun out there, but it's been 100% reliable.
Get a progressive shotshell reloader, and you'll save a lotta money if you shoot a lot. Shotshell reloading is MUCH easier than handgun ammo reloading...which is MUCH easier than rifle ammo reloading!
