When you say 'crush fit' are you saying when you close the rifle you should feel the crush of the primer nose on the primer shelf in the BP.... or you should feel the primer walls crush fit against the walls of you primer pocket?
The W209 is the longest primer out there but it is one of the skinniest... The CCI is shorter than the W209 but it is bigger in diameter - fatter
So which 'crush fit' might you be suggesting. When we were designing the new Lehigh BP - we started with the thought of fitting the primer to the primer walls of the BP. That di not work well becase it limited you to one primer. We eventually ended up creating a primer shelf that the nose of the primer went up again to create the primer seal. When you put a W209 primer in a Lehigh BP you will actually crush the nose a few thousands again the the primer shelf in the primer pocket.
