I've got a couple fo pounds of WW 680 (I have no idea why I have them, never could find anything to use it in). As I remember, it is too slow to use in .44Mag. loads. That puts it about where AA 1680 is for burning speed. Are these powders similar? Or maybe the same powder reincarnated by AA?
I'm finally getting some .357 Maximum loads loaded, and the cast boolits have me in a quandry. The .357 M may well have all it takes to run my 358156es faster than they can go accurately. The boolits are pretty durn hard (probable linotype which I cast up years ago), but they used to be just on the edge of leading at high speed out of my L-Frame so I'm not sure they'll like 1800 fps or anything like that even if being shot out of and correctly sized for a rifle barrel. Lubed with Lyman's NRA 50/50 formula, and seated out to the bottom of the top land(!). Any one have a perspective on this?
I've got 2400, and 4227, which I think would do well. All of the ball powders don't want to be loaded down (yer not supposed to). And I really like Blue dot, a fantastic powder for making high velocity (relatively) in low pressure ctgs. The long seating to reach the rifling kind of messes all of the data up too. Anybody Have any pet loads that seem to fit here? I'm thinking of staying pretty slow 1400-1500 fps maybe (though I'd like to go faster)......
