Has anyone out there with a M94 in .357 tried using 680 with heavy bullets? It looks like one can pour about 18.5 grains of 680 into a .357 case and easily seat an RCBS 35-200FN to the crimping groove. Whether the resulting 1.8" long round will function through the action is up for debate, but it appears Paco Kelly has had success with Lyman 358315 in a M94 .357. To follow is a quote from one of his archives, "...with Lyman’s 358315 I get a 200 grain round nose with a gas check and 16 grains of 296 I get 1900 fps...and almost as good penetration (as 358009 at 1669fps) And it will cycle thru the action. I cut a small flat on the nose for the loading tube."
Anyway if 16 grains of 296 will drive a 200 grain .357 to 1900fps from a 24" M94, I'm wondering how fast 18.5 grains of 680 will launch RCBS 35-200. If I can achieve 1900fps with this bullet (24"bbl) with good accuracy and case life, I'll be more than happy. Too bad one can't buy WW680 in one pound cans anymore... I've already got a jug of 2230-C that's just sitting around collecting dust because it's too slow for my Triple Four and doesn't group well in my '06.
