Hi all. I am new to the board. I own a few Brno's including two in 458 Lott and my first rifle ever, a 602 in 375HH. I have shot almost everything with my 375 from warthogs to hippo and plan to use it on a whole lot more. I am an amature gunsmith and make all kinds of parts for my brnos including peep sights and front beads. Currently i am rebarreling a 602 to 458 lott (the old barrel was badly machined). I am trying to find out what the thread pattern is for the 602 action. It's between a 13tpi and a 12tpi but a scored thread prevents an accurate measurement. Hope you can help and I can return the favor. I have extensive loading data for lott and 375 and am a bit of a freak in this respect.
