Black decals from local print shop. Sig kilo 6k gives live but this for backup. Shipping tape over top to protect it from some wear. The decal peels off pretty easy. For sheep hunts I have a 7500’ sheet of decals I’d just slap one over top then peel off when back to normal elevations where most time spent. This one matched to the half mil hashes of dmx reticle past my zero. Wind at 6mph(10 kmh) although we do wind up here in kmh. So base 10 math done from 10 kmh base. Reticle allows some ranging ability to 18” buck torso so that column added as well. The red line is last line above 1600 fps.
Hope that gives some ideas. Not the cheapest way to do it, just one guys interpretation.
