I have multiple cans of Winchester Magnum Rifle, WMR1, powder. I am looking for loading data for .338 Win Mag in 210, 225, and 250 gr bullets. Are there any old manuals that are available on-line to see?

IIR, they are "the same" and might be too slow for the 338WM. I think it "close" to 760 (?) but slower.

I found some of the old Winchester 'freebie' pamphlets with an on-line search.


Doesn't look like it will hit full pressures till using the heaviest bullets. Mostly too slow for the 210s and 225s, it would appear. But if that's all you have for powder, it will probably go bang.
Thank you MikeG
This is exactly what I was looking for. I talked with another shooter and he said he got a lot of consistency with the WMR powder. That is why I was looking for the data. I am sure if I good accuracy, the end result with a .338 Win Mag will be very lethal.
