I have bought a good bit of this powder from an individual at the Dallas gunshows over the years. I used a bunch of it in a 7x57, found it way too slow for the 308 but useful in full power loads using 180 grain bullets in the 30-06. I took a bunch of game loading it to H414 powder levels but in many cases the velocity was ridiculously low but accuracy was excellent. I worked up to 57.0 grains of my lot of WC852 under a 150 gr. Ballistic Tip in my 270 (work up in your rifle) popped with a CCI Magnum primer in Winchester brass. Pressure signs are just not there, primers still have their full radius and there is no shiny spot on the case head. So I may in the interest of science work up until I can see primer flattening or cratering or any sign of excess pressure. I wish I had a chronograph. At one time I used 51.0 grains under a 130 gr. Ballistic Tip in a Savage 270 to take several deer and feral hogs, worked just fine too.
