Thank you Mike. I agree with all you are saying. I will use a marker and do what you are recommending. I believe the issue is the case started life as and ISR and was necked down to .318. I will know shortly if the bullets are installed at an angle. Visually it appears that way. I can get the case within a 1/10” of setting with a lot of pressure but wont seat flush. If this was a bolt gun would probably be able to chamber.
I will post my results later today.
Best Regards,
Phil
