In addition to what Stingray said, this issue was brought up to the NRA High Power Committee and was to be discussed and decided on at the April meeting, but COVID hit and the meeting was cancelled. That was unfortunate to say the least.
And to the NRA's credit they decided that a Match Director's Bulletin was the only timely way to get this information out to the shooters. Contrary to what some are saying, the NRA has the best interest of the sport at heart and are curbing what they agreed was a "right on the edge" (my words) innovation that could lead to the spirit of the rules being thwarted. Take a good look at what Walt Walters and John Seigler had to say about it. They know what is actually going on as opposed to speculation and gossip.
The bipod/mat setup in question was not the reason said shooter won. He won with pure skill, plain and simple. Anyone who knows him can attest to the fact that he is an outstanding shooter. But the bipod/mat combo was deemed to be dangerously close to being something that would go beyond the spirit of the rules, so it was shut down. And it was brought to the attention of SWN staff by a person that had nothing to do with any team of any sort.
Maybe if more people would concern themselves with preserving the integrity of the sport, rather than carping about ridiculous nonsense, we could move past this....This sort of crap is why I abandoned Facebook. Too many "Keyboard High Masters" running their mouths and stirring up trouble.
Peace, out.
