Dump the 777 and try a different powder. I shoot heavy conicals with 90 grains of Pyrodex, Clearshot (no longer made), or American Pioneer. I get a shove while firing. 70 grains of 777 has a sharper more painfull kick than any of the others shooting 90 grains. 90 grains of 777 rattles my teeth. 777, in my oppinion, just kicks harder than other BP substitutes, it has an abrupt rapid recoil and not a shove or push.
