Right,
The Tooley MBR does not fit into the configuration needed for short range BR... Additionaly even within short range BR, there are Score Shooters and Group Shooters and there are those that shoot both. depending on you shooting style some stocks don't work well for score as they do in group, and visa versa. A low rider stock like the Metric, Scoville, Pierce, Leonard is not so good if you are a back squeezer working your way around a 100 yard score target, A farley rest can change that. A Kelbly original Stock like the ones I have by Lee Six, aren't the best for a guy shooting group with a farley rest, like a lowrider type stock is. My Kelbly style stocks are on rifles that I use for Score, I have a Pierce Stock on my dedicated Group rifle.
I also shoot F Class for fun. I use the Kelbly stock, but I see problems there. The rear of the stock drops too fast for rear bag to be comfortable at 600 and 1000 yard shooting, when lying prone, there is a need for a cheekpiece, etc. I don't think there are many applications where a stock that is designed for one discipline can be effective in another.
