That is actually quite good for five shot groups at 100 yards/meters. N-120 worked well in my CZ rifle averaging around 1/2moa for five shots, but I just did some load testing with my Cooper this morning, and Lil Gun seems to be more accurate in this rifle. I started very mild, and the groups are tightening up as I increase the powder charge. I will step the loads up another .1 grain to 9.7 grains, and take my chronograph along when I shoot again. 9.7 grains is actually the listed starting load in the Hodgdons data, but many people are finding that they are matching the velocity for the maximum load of 10 grains, using only 9.6 to 9.7grains. I am using the 20 grain v-max, for all of my loads.
