I need some guidance please; I just purchased the Olympic Arms UMAR in 22-250 for coyote calling. In the past I would always carry a rifle (long range) and a shotgun (short range) but am interested in using a combo setup on this AR. A quality medium range scope (out to 500 yds) and a reflex red-dot site (short range). Is this doable, what would you suggest for the medium range and what would you suggest for the short range, as well as how to mount both. I would also be interested in hearing any guidance for hand loading for the Olympic Arms 22-250. Thanks in advance for the help.
