I've had mine for 19 years, it's killed almost every kind of small game, vermin and varmint out there, hundreds of squirrels and rabbits. It's gotta be well over 50K rounds and keeps on ticking, soup cans at 50 yards are in grave danger. I've always had good luck with std velocity HP's from Winchester and CCI. The last few years Winchesters Expert HP's have been good. Never had much luck w/ hyper velocity stuff (accuracy) and I prefer the heavier bullets anyhow. Never had a failure to upset a HP at 5 1/2" barrel velocities as some claim might happen. I'm still using the factory open sights.
