Good shooting Sabotloader. If you notice the same Lyman 57 on my Lyman Deerstalker you'll see I have my sight smack down as far as it will go. At 100 yards shooting PRB I aim at the bottom of a 6" bull (or low on a deer around the heart) and it hits right on. I guess the only way I can get more usable adjustment is to get a higher front bead. I've been shooting it this way for a long time. I just compensate for shorter yardages. Your pictures just got me to wondering.
