Exactly, you too Roger F. I was referring to Roger S.'s post. Aiming at 6 o'clock to hit on the front sight is very much different than aiming at 6 o'clock ot hit the bullseye 3" above that point.
For instance, take a 4" bulls eye & my .40 cal. barrel, ball Ballistic Coeficient about .050, velocity 1,900fps - centre of bull is 2" above the bottom. With a blade, and sighted for the centre, but holding 6 o'clock, the ball is striking 2" high at 25 yards - with a bead and hiting centre, the ball's impact will be 3" high of the centre of a small bead. With a blade front sight, the impact at 50 yards will be 4" high at 50 yards, 4.8" high at 75 yards, 3.9" high at 100 yards and zero'd at 130 yards. Fat lot of good that does us. With the bead fron, but sighted to hit the centre with a 6 o'clock hold, the ball will be even higher at + 6.1" at 50 yds, 7.9" high at 75yds., 8" high at 100yds and 6" high at 125yds. The ball was still climbing up to it's peak at 90 yards of 8.2" high. With it's sight setting of 3" high at 25 yards, the ball never touches the centre of the sight unil it's a 157yards away- wonderful! That 6" high at 50 yards will make shooting a 3' wide by 4" high plate at that range a lot of fun - or any other range for that matter. How about golf balls at 25 yards? - NOT!
