DO NOT TAKE THIS AS GOSPEL I found this on another site from a few years ago. The guy as given 10 LBS of the stuff. "On the can it says "3 dram equivalent 19.0 grains, 2 3/4 dram equivalent 17.5 grains". I then ran some through a #28 MEC bushing, which gives a 17.7g average drop". I know it was from CIL the Canadian company and I read that they got it from artillery shells. Who knows if that is true. I also looked around the web and found this old MEC chart. You can see that back then MEC had it as the same as THE OLD HI-SKOR 700x
we used 700x data for c300 back in the 70's of course it needs different bushings to through 17.5 gr etc.weight your first charges to make sure.
