Definitely. They will all work. Here's another way by Bruce Teel 2 time national long range benchrest champion.

his and Eric C are the same except for amount of force applied to the cartridge . I think they all go to the same place just in different ways and terminology . I know in this game .002 is a lot but they all are within that after all they do . And this guy says after a match (500) rounds due to throat erosion his has to be redone it has burnt out that much.

Anyway Thanks for the discussion as always it has given me more to look at.
