I'm shooting 570g TSX's at a leisurely 2300 fps out of my 12 lb (with scope)CZ 500 Jeffery. Recoil is not an issue offhand, kneeling or sitting (except for having to get back up lol). I've learned to use a lead sled from the bench. It's taken some tweaking by both the CZ Custom Shop and AHR to get it to feed 100% reliably. If I had to do it again, I would have probably saved up and bought a custom rifle in the caliber, but I've had a lot of fun with this rifle! It's very accurate, comfortable and a hoot to shoot! I'm looking forward to taking it to Africa and Alaska in the next few years.
