I just put about 2 pounds of 3031 through a 3BR Redding....I finally figured its rhythm.
I can't help but thinking the IMR line as a misunderstood, under-appreciated series of useful powders.
I tend to think volume and less grains; with shortages and high demand, we've bought a few kegs of the old standbys and made them work well, like they always have.
not by me, I burn more IMR powders thru my rifles than the other brands combined...because they work, are consistent and have been so for a lot longer than I have been alive...
