Seat the base band , 1 grease groove , the next driving band and crimp in the next grease groove .
This will give you about the same powder capacity as a RN or SWC .
I do this with 148 gr. and 160 gr. Wadcutters in 38 S&W and it works fine . I have my grandfathers 38 S&W DA top break and enjoy shooting it with cast wadcutters .
700X seems to be the velocity leader with this round !
Hope this helps ,
