Re: My new 9x58.5r Sauer DR

With 180 gr GC bullet and 25 gr of IMR 4198, I am getting ~1850 fps. The 50 yd group was about 2 1/2". I would like to try more with the powder. Unfortunately, I am about out of 4198.

I loaded some case with R7 which is supposed to be a little faster burning than 4198 but the 25 gr loads were slower and the groups were larger.

I will try several loads with 3031.
