I tried it a while back in a .222 but didnot get good groups .
I ran some through my autoscale and it meters like ball powders.
I tested 15 drops at 15.5 grains and they were all 15.4 to 15.5.
I loaded up 20 -357 158gr xtps for a test. ill run them across the chrono and check for speed. accuracy. see what if any pressure signs. i got the powder at a gun shop off the clerance table for $8 bucks.
thanks Dave
