I finally broke down and purchased some Hogdon 777 in the FFG variety.  I loaded up my Pedersoli 12ga double with about 70 grains of it, over powder card, wonder wad on top of that, 1 1/8 oz of lead 7 1/2 shot, and an over shot wad.  I didn't really paper pattern this load, but instead just went to shooting clay birds and did I ever SMOKE EM.  This stuff really burns clean and loading up again was easy, no soot at all.  No stink when cleaning either.  I think I like this stuff a lot.  I wonder though, why Walmart tries to rob us for it.  I bought it at Scheel's All Sports in Omaha NE for $19.95 and it's around $25 a lb. at Walmart.
