Page 4 for MG42 with steel shot.
I like the MG42/STS (Formerly known as the Steel Target Special Wad) wad from Ballistic Products, ask for the-
MG42 12ga Cushioned Wad data sheet #LD12MG42081205 from BP when ordering or PM me your email and I'll send it.
That sheet contains info for several different powders including Unique, SR7625, SR 4756, Herco, Universal, BlueDot, HS6, HS7, Longshot under 3/4 to 1 oz of steel shot.
1 oz loads crimp nice without spacers. I've loaded 3/4, 7/8 and 1 oz loads in the MG42. They all work well on clay with #7 steel. The 3/4 oz load over Unique is incredibly soft shooting at 8200psi/1270 fps. I like this load enough that I bought a bag of VP51 wads to get away from the filler. As soon as I can resupply myself with Titewad, I'll be giving those a whirl.
