38 spl. shot using gas checks?

I've loaded many snake shot rounds loading gas check down to powder charge, fill with #9-#12 shot, cap with inverted gas check and crimp with heavy roll crimp. Best to use Bullseye so your charge takes up minimum space. 3 gr of Bullseye or 5 gr of Unique. You really can't overload a .38 Spl case
