Was wondering what are some of the powders being used in this category for a 150 grain bullet with the K31?
I have H4895 and IMR 4350 which would fit this category.
I called Hodgdon and the man said to use 43.0 grains of IMR 4350 for the K31.
In other words he said to reduce the H4350 data by 2 grains.
The only two manuals I have that list the 7.5x55 give 45.0 grains for H 4350.
40.0 grains for H4895, which would fill the case about 3/4th full.
The only other powder I have that is listed in the load data is H335 and it would fill only a little over half full.
Don't to use a filler unless absolutely necessary.
