Update: I am getting under 1 inch groups using 170gn HCSS Speer with 47.0gn of RL15 and with 160gn TTSX loaded with 49.0gn of Varget. Both are 0.020" off the lands. I cannot wait to see what happens with the second loading of the new brass. I full-length resize, but only bump the shoulder back about 2 to 3 one-thousandths of an inch. GENERALLY, this improves the groups. We'll see....
