We are shooting a rifle with the 4.5-14 x40 Buckmaster . We have added the monarch high replacement turrets, about $74 from amazon. They turn it into a nice 1/4 moa click-in setup. Good optics, nice crisp clicks, easy return to zero. Using some good handloads that we run through the chronograph and the $10 isnipe iPod app, we have shot out to 700 yards. My 13 y.o. Son got a nice mule deer at 454 yards last fall using this setup, shooting off a bipod. We have a local range with hanging steel plates out to 1200 yards, 700 is the longest we have tried yet. As mounted, I run out of clicks at 890 yards, trying to decide if I get a 20 moa rail and remount the scope. It has worked well for us, fun to shoot and didn't cost 2-3 x the cost of the rifle. Go with a nikoplex reticle, not the bdc and figure out how to click in to zero. I have been impressed with what it has done so far and haven't had any trouble with it holding zero. The money you save can make it easier to get some of the other long range accessories. Like a good range finder, chronograph and wind gauge. Happy shooting!
