Marlin GBL load help?

[jeffrice6]

Purchased a new GBL and a Ranchdog 425Gr half GS/ half PB mold. Ranchdog has some great data on his site, but I can't find a 45-70 load anywhere for a 425gr cast PB boolit. Anyone have this mold, any info, or a place to look? Thanks

I use 40 grains of 3031 in my GBL with a 460420 plain based boolit. Very happy with the results. Goes 1500fps and doesn't hurt.

PS I also use a tuft of dacron. It tightens groups up.
