everything I've read says they are the same . use the same data . the short cut will meter better in your powder measure .
if I were using it in a large capacity case I'd use the 7828 , I like a full case . if I were using it in a smaller case I'd use the 7828ssc , I don't like a compressed load . Jim
I want to warn you that my experience is there are pretty big differences between cans. I have found as much as 5 grains difference. Now to qualify that more. I am speaking of the one pound flat cans and the newer round bottles. I have a brand new 8lb jug I will shoot from in the next few days and will post the differences. I loaded an 85 grain load from a flat can and the power in the newer round bottles was 5 grains hotter.
Part of the problem was some of the powder I had was made before Hodgon bought them. I now have three partial empty cans that are all different.
It is one of my favorite powders but be careful. After blowing out primers I take it careful from jug to jug.
With my experience there is a different, the 7828ssc is a little faster, maybe because of the Super Short Cut, I know lot to lot will be different but not that much I would think, with the same charge weight of both powders in two loads in my 338 Lapua, the 7828ssc average 151 fps more with 300gr SMK, 118 fps more with 250gr SMK.
