It's been quite a few years since I owned one of the Browning 71 carbines, but checking my old logbook shows my best load with 200 grain Hornadys was 53 grains of IMR 4895 with a WLR primer loaded to 2.820" OAL. Five shots (with a Williams receiver sight) in 2" at 100 yards. I never chrono'd this load, but I'm guessing it was in the neighborhood of 2350 fps. According to my old Lyman manual, 54.0 grains of IMR 4895 was supposed to duplicate factory velocity.
