Gosh, whichever one you have most of on hand I guess. You are very fortunate to be at the point of splitting hairs here.
I have very little experience with 7828 and really haven't used any in years. I probably load as much Re22 as any other powder combined, however.
I like the smaller kernels of Re22 powder, but I've not seen the latest 7828SSC either.
Why don't you just load a sh_t load of ammo using all of what you have in both powders?
