I've always started at minimum loading 3 rounds to mag max length increasing in 1/2 grain increments up to max. From 100 yards slow firing each 3 round group with a 4-5 minute break between groups to find my node. Then going with the best group(s), and loading 3 rounds in 1/3 grain increments.....ya get where I'm going, lol. Then shoot at 200, 300 etc til I reach how far I'm going to shoot with that rifle, making adjustments as needed. Have never tried a ladder test but giving the lack of supplies lately, my theory is I could use less ammo starting at 300 yards with assumption if its on at 300 it should be at 100. The max for this particular rifle will be 500 yards. Any thoughts and/or opinions from you guys who've done both would be great.
