The recoil in my 500 Jeffery in a CZ 550 Safari Classic isn't bad at all. Of course I'm not up to full power 500 Jeffery loads yet. I'm shooting 535g Woodleighs at around 2100 fps instead of full power loads(570g at 2300 fps). I had the CZ Custom shop put in two recoil reducers and a Pachmayr XLT recoil pad, so it weighs in at 11.25 lbs without ammo, scope or sling. So far it's fine with my Leupold 1.5 - 5x from the bench shooting 535g Woodleighs at 2100 fps or so.

Best of luck with your 50!
