Correct me if I am wrong, but I thing Prairie Dawg is asking if Lightnings are given their own category in the scoring breakdown within the speed rifle side match. Sort of like how fastest shotgun gets broken down into fastest SxS, 97, and 87.
To answer the OP's question I have never seen the Lighting given its own category. Why would anyone want to compete in a side match with one or two competitors?
I believe I have only ever seen two Lightnings used at SASS matches in person. They functioned but were not fast compared to even a middle of the pack 66/73 shooter.
