296 is also an interesting powder for the .22 Hornet. Probably due to a very long shoulder, powders that work well in the .357, and .44 Mag, work to give top velocity in the Hornet, though the shoulder of the K-Hornet would scare me with these powders. A 40 gr bullet, with 11.7 of 296, in my Brno, gives just over 3,000fps, accurately! I know of no other powder which will exceed Win. factory velocity by anything close. In my Marlin 1894's, it's all I use in both .357, and .44Mag. 2400 is accurate, but dirty; 296 is pretty clean. Loads for these guns exceed considerably the recommended max for Colts, and by a bit what I would use in a Ruger. Gonna try next in a .45 LC Win '94 Trapper; I can fit a 300 grain buttet in there! Will report after my next range day.
