If your on paper at 25 yards and shooting maybe 2 inches high, try shooting at 50 yards. If you have a good group you know you can take a shot at 50 yards. Shooting at longer distances, in my opinion, makes me a better shooter. Also try Dutch Shoultz's shooting system, it was one of the best $20 I spent in a while! Your patch size shouldn't change at greater yardage unless your burning through patches with a higher powder charge. Find your patches and they tell the story. Accuracy is the final test. Good Luck!
