buckstix,
After you were so adamant about chamber casts, I was disappointed you didn't show the ones for the 30 Couger. I usually had no trouble with "tip up" guns, but bolt action rifles always gave me trouble, especially with the cerrosafe running into recess for the locking lugs and hampering removal, as well as measuring the part of the case length between the bolt face ant the end of the barrel. I had to remove the barrel and measure the action, as if I were fitting a new barrel. I was interested in seeing how you do it quickly.
