[QUOTE="orkan, post: 2963891, member: 25377"] Kind of hard to see the primary extraction from that pic... the area we need to see is the root of the bolt handle where it hits the cam on the action, with you pulling the handle rearward to remove the slop. Bit of primer cratering there. Could be false positive due to your bolt face/pin fitment. Potential extractor mark at the "c" on creedmoor. Could also be false positive from machining burr. (you can stone it off if need be) You can measure a fired case web expansion at the .200 line (last supported area of web) and see if its larger than chamber spec to confirm if pressure is the cause. ----------- [URL='https://www.instagram.com/primalrights']Follow on Instagram[/URL] [URL='https://www.youtube.com/user/primalrights']Subscribe on YouTube[/URL] [URL='https://amzn.to/3txlBnp']Amazon Affiliate[/URL] [URL='http://www.primalrights.com'][IMG]http://primalrights.com/images/signatures/sig2.jpg[/IMG][/URL] [/QUOTE]
