I have recently purchased a 1992 model BRNO ZKK 602 .458 wm and it has seen very, very little use. I am looking at reaming it out to a 458 Lott. Anyone done this with their own 602??. Did anyone experience any problems with the feeding (or anything else) after it was done?

I have a Ruger in 416 Rigby and another 458wm so recoil is not a problem.

Cheers
