RickSmith,
Even turning the seating stem counterclockwise to its uppermost possible position (before it is totally unscrewed) the loaded cartridge is shorter than what I'd like.
I am not sure I understand what you mean when you say "so that at least 1/4 inch of the sliding sleeve is exposed at rest"... Do you refer to the amount of sleeve that is protruding under the body of the die?
Thank you!
