Don't shoot it myself, but have lots of friends that do. It's a league that's mostly in WA and MT with one match in WY this year. It's a team match, shoot together with your partner where one can spot and call corrections for the other both engage the same COF under a single time limit. Usually need to range and dope on the clock, time allotted is a bit more generous than typical PRS comps. More field style, natural terrain matches with a higher percentage of prone shooting, but still lots of creative positional stuff using natural terrain or tripods to shoot over brush, and even some barricade shooting like PRS. Lots of matches will have a mover stage as well. Most matches are 2 day events. Requires you to be both a good shooter as well as function effectively as a team.
There are some good shooters that participate. Winners of the series point race last year and so far this year are a team made up of two guys who are very strong national level PRS/NRL shooters.
