I'm going to add that to my list of powders. Data looks pretty good, from Hodgon's online reloading data: 55gr compressed with a 400gr bullet will put out 1845fps (3024 ft/lb) at only 25,000 CUP.Try some Varget if you have any. You can get Varget loads downright painful and frightening, but still be in "the zone".
Going to have to make a trip out this weekend so I will make the loop and look for powders. I've got the chrono again this weekend so I hope to be able to do some work on loads.
