I am wanting to try Unique powder for my 1943 Mosin Nagant but my Lyman 4th edition does not show a load for it. Has anyone tried Unique and what was the outcome?
The Lyman 4th edition showed the most accurate powder was XMP 5477 which I tried in the M/N and had very poor results, some shots off paper at 50 yards. I was using the Lyman 314299 boolits using 45/45/10 lube and my bore had slugged at 312. No fillers were used.
I tried XMP 5477 in my Tikka .308 (with Lee 309, 160 grain boolit) and had poor results also, however had some good groups with Unique. The Lyman 4th edition had also listed XMP 5477 as the most accurate powder for the .308.
My goal is to use one powder for both weapons if possible.
I appreciate any and all feedback.
