I use Dan Newberry's approach. After i find the best group of 5 different loads i start messing with the COl. After that you can tweak it a little more by messing with the powder charge in 1/10 gn increaments. Remember-What shoots good at 100 yards is not always a good load. You need to test at 200 yards min-300 would be best.
