I thought it was gonna be the schizz in my .375 Weatherby when I was doing initial load development.
I tried several different charge weights, in 1 grain increments. The loads were running from 8-15 fps extreme spread !!! Incredible consistency !!! Yet I couldn't get under 3" for 5 shots at 100 yards. For whatever reason, my rifle hated the stuff.
Never tried it in anything else.
