If you're not afraid of fowling and a little more cleaning, its hard to beat good old Pyrodex and Goex. You could try them in 2f &3f grade and they might work just fine. While you might have to vary the charge to get the same effect as your Triple Se7en, now that season is over, it would be a lot of fun to just try. I think too many people avoid these powders because of fowling. I figure I have to clean my rifle anyway, and I like the performance I get from them.
