I'm headed out in the morning to test a couple load workups in the 30-30 which has iron sights. I have noticed that my eyes don't shoot irons that well these days. I can shoot them well enough to hit a paper plate at 150 yards but anything over 50 yards for accuracy is stretching it. Will I get any meaningful group data at say 25 or 50 yards or would it be best to do the best I can at 100 yards.
