I strongly recommend you use Federal 215 primers and keep your load density up to avoid hang fires (I had two before I learned this in my 500 Jeffery and they are very scary). I'm using Barnes 570g TSX's, Jamison brass, Federal 215 primers and 103g H4895 with an OAL of 3.63" in my CZ 550 in 500 Jeffery for just over 2300 fps and sub MOA accuracy. Recoil is "sporty" but not bad at all off hand. From the bench I've learned to use a lead sled ... Picture of my 500 Jeffery in my not so neat garage ...

It's a great caliber, I hope you enjoy it as much as I have been ...
