We shot a match today that overall I sucked, but came away with my new personal best 5 shot group at 600 with a 5 shot measuring 1.515".

I will be off tomorrow and see if a tension adjustment will help my overall groups.

With my brass seemingly beginning to tire I added some neck tension to see if my vertical will go away at 600.

The 1.515" was small group of the match. \:\)
