I have both 602 and 550. The 602 is a 375 Weatherby (rechambered from H+H) and the 550 is a Rigby. I bought it with the idea of rebarrelling to 470Mbogo but haven't got it done yet. I have a Rigby in a Ruger and it's a much nicer rifle to shoot. The POS CZ hogback stock is brutal. I put the 3 pos safety on the 602. I like these safeties. When on safe you see it as you look thru sights. Mark
