[QUOTE="J E Custom, post: 737420, member: 2736"] Hang around on this site long enough and you will see something new. I have been loading for over 50 years and I have never seen this much soot. Give us your loading procedure and loads and maybe we can help you. Normal soot is confined to the neck because the case seals it,s self off before it get beyond the shoulder. All I have is questions at this point. Are you full length sizing? What primers are you using? What powder are you using? What is your neck to chamber clearance with a loaded round. What is your head space? Your smith is right about the free bore. The RUM,s and the WSM,s along other High pressure cartriges need free bore to keep the pressure down and the velocity up. Most of the Weatherbys have more than .300 thousandths free bore and if you reduce this very much you will not be able to shoot factory loads and you will give up velocity. The problem as I see it is that the case is not expanding enough at initial firing to expand the case, sealing it off in the chamber. Please keep us posted on this problem because we can all learn something new. J E CUSTOM [/QUOTE]
