Since this seems to be the go to R8 thread i would like to get some clarification. I spent about an hour on the phone today with euro optics. Fella named Derek, really helpful with all my questions. What I need to know is do I "have to have" the steel reciever to shoot the big cartridges like a 458 Lott for instance. I'm looking at getting one set up in 338 lapua or maybe a 300 win/375H&H combo that seems to be popular but I shoot a ton of lapua and would also like to be able to shoot the Lott in it. Do I need the $2000 more expensive steel reciever for that or will the normal R8 professional handle the big calibers too. He kept saying they reccomended it but then would say I mean if you're not gonna shoot it a bunch it probably wont hurt. Euro optics is 12hr away so I want to have a pretty solid plan before I drive up there
What @TOBY458 saidIt's not needed for strength. It just ads weight to absorb recoil. But if you add a kick stop in the stock, it seems to me like you can get the weight up without needing the expensive steel receiver.
And Derek is good people. Don't be afraid to negotiate price with him.
