12 Ga blanks data?

[toxic]

Bit of a weird ask.... Can anyone point me in the direction of some published load data for 12 gauge blanks?

Smokeless blanks don’t make much of a bang. Black powder blanks do. 30 -40 grs Goex , a regular wad filled with cork wads and cardboard wads to bring the height up for proper crimp.
