loading 9mm 125 grn LRN with Unique. I loaded up test rounds starting at 4 grains and by tenths went up to 4.4 grains. the 4 grains shot a pattern like a shotgun 4.1 a bit better til I got to 4.3 a nice group and 4.4 started to open up again. It never cases to amaze me how small a change in powder weight can make such a big difference in group size. the best group was about 3 inches at 15 yards which is not great but I am fairly new to pistol shooting and the gun is brandy new as well. I am sure as I practice I can tighten this up a bit.
