Re: Help Trouble shoot ' Click then boom'
If you are talking about the round mark on the head of the case this is head stamping caused by the ejector. It is common with 700's and can be a sign of pressure as loads get hot. You need to bring it to a smith that can trouble shoot it. It could be several things that will be easy to eliminate If you know what you are looking at.
