Way to go Ken- looks like it might be a keeper. Do you know the twist and groove depth? I am impressed. Looking foreward to seeing how it shoots at 50 yards and beyond.
I usually make the front sight blade about .020" lower than the rear's top surface if flat topped. With beads, I use the centre of the bead to the centre of where the bead sits in the rear sight, but the same .020" lower for the front.
This sighting usually makes for a slightly low impact at 50 yards with larger than .40cal. Of course, it depends on the load one uses. Normal light loads used today by many, may require a bit more filing - no big deal - a few swipes, shoot, few more, shoot- bingo. Filing the front sight blade down a tich brings impact to centre. With a bead, I carefully reduce the height, then file it back into a round circle - this will result in a smaller bead, but that's expected as I start a bit large, but useable if it's spot-on.
With the Italian Enfield Musketoon I just picked up, I filed off the low rear sight, slotted the base and soldered in a new slightly higher blade - took a guess. On testing, offhand, I found it to be just about 1/2" low and 1/2" to the left. The three shots I fired offhand for testing - about 20 or so yards, put them all into a 1" hole. Taylor and the other guys were there. One small swipe with a file and tap to the left for the blade with my starter's knob, put it right-on. Even the trail's 2" diameter handing pipes at 20 to 35 yards were easy to hit.
