I tried the Lee 90 swc for the first time this morning,out of my single six. Four grains of Unique was the first load I tested. I about fell over when I looked at the target - two touching, one three quarters away. I went back to the bench and shot the same load again. Same thing, honest one inch group. I tried up to 4.5 grains but the Lee seemed to like 4 grains best. Great plinking load right out the gate.
