I really hope the USARB survives the transition... many of our rifles are built for 25 Meters or Yards, not 50, many of our pellets perform at benchrest accuracy at that distance. Accurate is built into a platform and platforms are designed to get a job done at a specific distance, A good 200 yard gun does not make a good 25 yard gun, and visa versa.
In powder burner Benchrest where I've spent the last 30 years of my life there are different organizations that do Group and Score, and within those organizations there are "Point blank" 100-300 yds. shooters, and "long range" 600-1000 yds. shooters. I see the EBR, and N50 concentrating on the longer distance game, leaving the "point blank" game behind. It's possible for guys to have multiple rifles built for the multiple games without cancelling the existence of one game or another.
In the IBS at the annual membership meeting we always had both sides of the game attending and coming to agreements on match scheduling to not over book for big matches... for instance, the 1000 yard or 600 yard nationals never were in the same week or weekend as the 100-200, or 200-300 nationals. For the sake of the shooter that likes both games, I hope we can work together so 25M or yard does not disappear. Also the NBRSA, and IBS have close range and long range within the same organization... just because you shoot 50, or 100 doesn't mean your organization has to overlook the 25M game.
