so you're shooting bottom right? I like to set my in-lines ML's at 12:00 and about 1.5-2" high at 100 yds. The flinters are set close to 1" high at 50 yds as my eyes are not so good with open sights anymore and a 75 yd shot is fairly long for me. The 54 Hawken with the 36" Green Mountain barrel is really accurate but these eyes have trouble getting both sights in focus and I hate it. I said before maybe a peep might help moving the rear sight closer to my eyes and then change my glasses to clean things up? Scopes make things a whole less complicated but then there's nothing like woosh...bang to shatter the morning stillness.
