I have been trying to master a Chassepot 1866. I finally got down making paper cartridges for it, but now I need to shoot it at 50 meters (50 yds), because the range where I can easily shoot is only that long. I bought the rifle from someone who did quite well with it at 100 meters. The problem is it has a lot of adjustments for long range, but at the minimum, it’s one meter at least high at 50meters. I don’t want to do anything to alter the gun that can’t be undone. My thoughts are to add some epoxy paste to top of the front sight to lower the point of impact. Is there a was to calculate how much appropriately to add? It should be zeroed for 100 meters and 50 being half that, I suspect that the boolit is at around the apex of it’s trajectory. Does there exist a formula to calculate this? Otherwise, I’ll put on a significant amount of epoxy and start filling down until it gets close.
Thanks
