[QUOTE="Mikecr, post: 116560, member: 1521"] I use a K&M primer tool w/dial indicator. With it I can get the recommended crush of .002" It does this by doing a simultaneous measure of pocket depth to primer thickness(To Zero indicator). Then you can seat to .004 past this zero, and I've found that the primer will usually back out .002 within 10 minutes or so. With every shell I set this crush as measured. I've looked away to see how close I can get by feel, and surprisingly I get pretty close. Especially w/Lapua brass and plenty of practice. It's nice reading the number though and knowing my primers are seated as accurately as my bullets. Primers are so strong, and such a random element, that it probably doesn't even matter. I've fired 20 primed cases at a mirror in the dark to somewhat see whats going on. Many shots were clearly different than others. But all more than needed to ignite confined powder(overkill). I think thats whats going on. [img]/ubbthreads/images/graemlins/smirk.gif[/img] [/QUOTE]
