I have a cz550 in 458 lott. I have a little bit of data from the hornady manual but there isn't a lot out there on this thing. Anybody have any pet loads. Reduced or full house barn burners. I'd like to hear what you got. Range and practice loades as well as game day loads. Thanks guys. I have some hornady 350gr bullets and I'm gonna get some heavies. I have a ton of varget. I've heard its good. What else works in this rifle?
