[QUOTE="bruce_ventura, post: 722540, member: 34084"] I agree with others here that the bullet drop compensated (BDC) reticles are useful out to about 500 yds. Beyond that range, you should dial elevation. You should calibrate the reticle for your load and elevation. Calibration is done by first zeroing the rifle, then using the lowest holdoff line to fire at a long range target (that is, use the 500 yd line to fire at a 500 yd target). If the elevation is off, rotate the zoom ring a bit to get the point of aim to coincide with the point of impact. Then check the accuracy at an intermediate range. Finally, mark the zoom ring with tape or paint. I use a boresight collimator to rough in the magnification setting. I like the Bushnell Professional Boresighter, but others will work too. The collimator has grid lines separated by 4 inches at 100 yds. Ultimately, you still have to confirm with a live fire test. [/QUOTE]
