Re: 210 Berger, 300 WSM, H4831SC loads?
4831 SC is a VERY stable and consistent powder. If you decide to work up a load use both a Magnum and a standard Large Rifle Primer, you may be surprised at how well the standard primer does with 4831SC in what is supposed to be a magnum case. I have had some excellent results with 4831SC and CCI BR2 primers in 6.5 x 284, 7WSM, and even 338LM.
