Nikon m 223 3x12x42 riflescope - Nikon M-223 3-12x42mm SF Rifle Scope

Matching the exact velocity required for the exact bdc marks was not really that important. I loaded a variety of different ammunition (none to the exact 3284 fps) and had successful shots past 500 yards. That was more than I hoped for. With a lower speed bullet, simply follow the instructions. I was using cheap varmint bullets and I combined the scope familiarization with barrel break in. For the money the glass is pretty darn clear. An illuminated reticule would be great but for the money it is hard to beat.
