[QUOTE="swampratt, post: 2774482, member: 15054"] Another note is when I set the die in the 4 hole turret press I set it to touch the shell holder and turned it until all slack was removed from the aluminum turret. Then I gave it another 1/4 turn.. When I checked how much I was setting the shoulder back on the Lapua case I found i was actually pulling it forward .003". If I turned it in less than 1/4 more I set the shoulder back .003" Then split that to 1/8 less the FC brass shoulder was set back .003" I think I need to do this with a stouter press as that aluminum insert has a bit too much give or something. It does still turn out decent ammo. But for ultimate brass fail test i think all shoulders should be set back 0000 to .001". BUT the last 5 shots with pulling the Lapua shoulder forward .003" resulted in only .001" case growth.. yes they were stiff to close the bolt on. Like I need another test. Pull shoulder forward .003" for less case growth and longer case life.. who wants to test that. [/QUOTE]
