I understand the 70-150 as being a wildcat, etc.
I merely used a standard 2 3/4" plastic case for my 12 bore loads with round ball, up to 191gr.(7 drams)
These were with the trap-load shot-cup gas checks, loaded cup-up, holding the ball in the middle of the bore.
I did buy more Tanner moulds, casting .705" and 724" round balls for various loads in 12 bore & one at .740" to try in an 10 bore Brown Bess with denim patches, which worked very well.
