I graduated HS in 06 also.
Shocker shot good initially Sunday, then I started getting really bad bolt stick and without doing anything the issue went away and it shot fine all day.. though it wasn't as smooth feeling.
Shouldn't have replaced the few orings I did before playing.. I find lately with this eigen that I'm lubing before every game day, and replacing orings every two lube jobs. Getting annoying since I'm burning through what I thought was a huge stash of orings.
