Any relatively fast powder with 7/8 oz or 3/4 oz of shot will do well. These include Clays, Clay Dot, Red Dot, E3, etc. Pressures go down significantly with reduced charge weights.

I load 7/8 oz in Rem STS hulls w/ CB wads, Win 209s, just under 17 grains E3. Pressure well under 7000 psi, velocity about 1250-1275.
