im shooting the 165 NBT with 68gr. H4831sc in my remington 300 wsm
with excellent results. My rifle also likes the 180 NBT with 66gr. H4831sc with a COAL of 2.910. the 165 COAL is 2.905. both these loads are .5 groups at 100. When it gets warmer out i will be trying both these loads out at 300-750 yds. but until then i'll just keep experimenting.
