They hold their loads to SAAMI pressures. It won't blow up your rifle if it likes 57-59 grains. I have found Barnes to shoot "fast" like Partitions seem to do. Just work up as usual, you'll know.
That's what I figured. Will probably start at 55.0 and work up in .5 grain increments. They advertise 2825 FPS with the max 55.5 grain load, and I'd like to be somewhere around 2850.
