Having loaded several different lots of WC 844 I can state that they do vary in burn rate. Most lots have been close to H335 but I've had one lot that I stopped at 24.5 and another where 26 grains wasn't quite top loads. Just work up looking for pressure signs and accuracy. Also, don't use load data from the Army Ammunition Data Sheets TM 43-0001-27 . All powders I've loaded for 30-06, 50 BMG, and .223/5.56 at the charges in the Army pdf. files would most always be dangerous. Use the Army Ammunition data for types of bullets, possibly seating oal and not much else.
