I've read loading data that uses IMR7828. I was at a local sportsmans store and they had IMR 7828sc. I'm trying to determine a load for my 338 win using barnes tsx 250 grain FB, and they list a load using IMR7828ssc. Are these all the same or different powders? thanks.

thanks for the info. Do the use of theses different size powders produce different load densities. For example if the 7828ssc calls for 70 grains and has a 101% load density, does the 7828 in 70 grains also have a 101% load density? Thanks.

i would also look at reloader 22 and reloader 25, maybe even h-1000 or h-retumbo.

This is exactly what it says in my `08 "Hodgdon Annual Manual for Reloading"
IMR 7828 SSC.......Quote!......"This magnum rifle powder has EXACTLY the same burn rate as standard IMR 7828 and USES the same data." "However, due to the super short kernels, metering is virtually as good as a spherical powder." "This ALLOWS up to 4% more powder space in the case and in many loads yields more velocity than standard 7828." "Such loads are marked with an asterisk in the data to show where the standard 7828 will not fit."....Unquote!
For the 338 WM, there is no data for IMR 7828 SSC in this manual. Just use the 7828 SSC powder using the standard 7828 loading data. Your density will be reduced with the SSC powder by about 4% using the same charge as the 7828!

BULLET: 250 gr. HDY SP DIA: .338" COL: 3.340"
Starting Loads Maximum Loads
Powder Grs. Vel. Pressure Grs. Vel. Pressure
IMR 7828 70.0 2423 44,000 CUP 75.0C* 2628 51,800 CUP
At the bottom of that page it says this;
*MAX LOADS THAT SHOW AN ASTERISK FOLLOWING THE "C" FOR COMPRESSED LOAD, WILL NOT FIT WITH STANDARD IMR 7828.... REDUCE BY 4%
You cannot load the standard IMR 7828 using the above 75.0 grains! But you CAN use 75.0 gr. of IMR 7828 SSC..............................

I would tend to agree-- maybe 185-210 gr rounds for most game out of a 338 or as a gen'l purpose round , and 210-250 gr.s for heavier game like moose , big elk , and stuff that can bite ya back... |
