I was hoping that someone might be able to help out with 2 rifle loads from German guns. Both loads were taken off the barrels and I would like to find out if there is a close substitute for the powders that they used to use.

The first is from an 8.15x46r which is stamped:
09 Bl.G
11gr
further down the barrel is 7.7m/t 46

#2 is a cape gun in 8x58r Sauer

2g GB.P.
St. MG
7.7mm

I already have loads for both but I am curious to see if there is something more suitable.

I thought I had the cape gun regulated but as soon as the hot weather came that all went out the window.

Thanks

Tom
