Have come across a simular type of back sight I thought it was too allow for windage at long range {any comments}
Feltwad
try this one out:
Maker drilled the hole that is centered. When shooter added holes he incorporated windage adjustments. If he got it right, then the top and bottom holes would be "on" and only the original hole would require sight picture adjustment.
In my mind that straightens the line between the holes.
Still, i'd likely drilled a new leaf (or hired it done), but i'm funny like that. (other ways too
)
You know if you remove the bottom hole, the top two don't look so bad.
I do expect to utilize a peep-sight of some sort in the future, when i can't see to use the "V".
