Although I shoot a 7mm rem mag and not the WSM version, I just worked up a load of 79.5 H870 and a 160 Accubond. Excellent paper results, .75" at 100yds. I will use this on moose next month. If these bullets retain the weight as advertised, with that kind of accuracy I will likely drop partitions where I can. I hope they expand the lineup and include .35 cals.
