What he said. You can also alter your zero slightly to allow the dots to hit at 300/400yds. Play with JBM software and arrive at a zero that has roughly 2.2moa of drop at 300yds and 4.8 at 400 for the LRD at max power. You may need a zero of 190yds or maybe 220. I then tweak it at 300yd steel until it is "on". After that, i verify at 200 and 400 to see if POI is reasonably close. Usually works on Spitzers above 2,750fps.
