[QUOTE="Fiftydriver, post: 35110, member: 10"] BDL, When you chamber a virgin round to fireform, do you feel the crush fit when the bolt is locked down. If chambered correctly, there should be 0.004" to 0.005" crush fit on the shoulder of the virgin case to prevent case strecthing. If you do not feel this noticable increase in pressure to close the bolt, your rifle is not chambered correctly for the AI round. The result will be excessive case strectching and in severe cases, case seperation just ahead of the solid case head. Something to look at anyway. Good Shooting!! 50 [/QUOTE]
