[QUOTE="Philward, post: 2820103, member: 92604"] Was just doing some testing with 168 ABLR. Rifle is Browning xbolt hell canyon LR in 7RM. previously shooting IMR4831 at 3003 vel, shot pressure and velocity ladder with IMR4955, 7828ssc, 7977, since didn't have any more IMR4831. And we were just starting to use Peterson brass. 62-64.5 using 4955 with velocities of 2940-3079 with a little stiff bolt at last 2 charges. 7828ssc was 63-65.5 with velocities 2850-2982. 7977 66.5-69 grains was 2855-2989 velocity. 7828 group was tighter than the rest and 4955 the largest. Never got tight bolt lift with 7828 or 7977. This was with virgin Peterson brass and Rem 9.5m primers. I could hear and feel kernels crunching when seating bullets with 7977 powder. [/QUOTE]
