Does anyone know of any possible way to zero a LRF at 100 yards to be effective at 800 to 1000 etc? Basically I have a Wilcox raptar and I just have no where I can go and zero it with a reflective target setting it up at 800 yards….100 yards no problem but I can’t fine tune at say 800 yards. My home range has the yardage but I can’t just walk down range and set up the reflective target. Are there any paper/reflective targets etc on the market that can solve this? Or even any techniques someone might have? Thanks in advance.
