7mm STW and 7828 powder

[huntokanogan]

Thanks for all the posts responding to my question guys!
So it sounds like 7828 is the right powder for my STW.
Question: Is 7828 a good powder for all bullets? I plan on trying 160-180 grn. VLD's, Accubonds and Game kings. (Sirroco's? do they come bigger than 150grn. in 7mm?)
When looking at the 7828 in midway usa there was regular 7828 and there was a 7828 with some letters behind it (can't remember what they were now), which one do I want?
Also, Would that be a good powder out of my 8mm Rem. mag? or are there better powders out there for that big nasty 8?

I tried a number of powders for my STW's and kept returning to 7828 with the 160 TTSX.

There is another version, 7828ssc. SC stands for super short cut. Same powder, but the kenals are cut shorter for better metering and possibly better compression. I believe it has the same burn rate.
