I've been searching for a secondary coyote gun, something semi-auto, flat shooting, and Non-Restricted (if you're from Canada then you'll understand). I settled on the H&K SL8-4 (WHEN I get the money WHEN I get the money WHEN I get the money WHEN I get the money). Now, I'll need an optic for it, and I need to know if anyone has used the Nikon M-223 Laser IRT yet. Especially, does anyone know how far the built-in rangefinder can actually go in the field? The BDC reticle is graduated to 600 yards, but can the laser actually reflect off an animal at that distance? Call me a skeptic, but I'm just not sure about the capabilities of an inside-the-scope laser rangefinder.
