The SB-200 was not only designed for 22 rifle small bore competitors, but also for varmint hunters and plinkers. It will easily hold 100 rounds in the down position for easy access during competition. Space in the center is available which can hold two full 50 round boxes. Recently retooled and now fits 17 HMR.
