Turns out to be TiteGroup in a new package, very dense and very small grains, so naturally some leakage from Mec loader with brass washer under rubber grommet. A load of 19.4 gr has little volume and a Fed SO3 clone and 1 1/8 shot doesn’t come close to filling Top Gun hull. Had a bag of the BPI frangible plastic OS card and that crimped perfectly but of course that’s extra time and expense. Does produce a mild pressure load at 1250 fps. The loading data and powder bushings are the same as Titegroup. They sure do make things complicated though, so thought I’d give you a heads up about the volume issue.
