[QUOTE="AZShooter, post: 1062297, member: 5219"] You have a different chambering than a 7mm-300 win mag. Headspace on belted magnums is checked with a very short go - no go gauge. This gauge fits between the bolt face and the belted portion in the chamber. It doesn't have anything to do with the shoulder. I compared the 7mm-practical base to shoulder dimension vs the 7mm-300 win mag. The 7 practical appears to be .210" shorter. I would try to contact the designer for some help: Email: [email]nathan@ballisticstudies.com[/email] Here is a link to his discussion with the 7 Practical: [url=http://www.ballisticstudies.com/Knowledgebase/7mm+Practical.html]7mm Practical[/url] if you cannot find Nate then I would also talk to Dave Kiff. Bet he knows what you need to do. [/QUOTE]
