winchester wsf and 357 , 44 magnum

Registered Users do not see the above ad.

since wsf seems to be a good powder for 40 and 9mm and since 357 and 44 magnum operate at similar pressures I would think there would be some data for the magnum loads as well. not looking for or expecting great performance just looking for some mild 357 and 44 magnum loads to use this powder on since I got it real cheap. found some 38 special and 45 acp data but would like to try it in the magnums. anyone have some date they would share?

The fact that powder is used in the .38 Special and the 45 ACP suggests it is only going to be useful for target loads and is too fast to fill the magnum cases well. The .357 has a little longer COL than the .38 Special, and with faster powders you can pretty much duplicate .38 Special ballistics by using the same bullet and bumping the powder charge up about 10%. The .44 Magnum, on the other hand, has almost the same max COL as the .44 Special (actually 0.005" shorter), so any load you find for the .44 Special will have its ballistics pretty exactly duplicated in the .44 Magnum, assuming same bullet, same COL, same primer and charge, and same barrel length.
