[QUOTE="Bravo 4, post: 612945, member: 8873"] I agree that BDC turrets are not a cure all one-stop-shop. My opinion is that they do have their place, and a turret with BDC as well as MOA (or Mil) offer the best of both worlds. However, the numbers don't have to line up to use it as a reference point. I have to do this every time we are on the range with the M24's. Like I stated earlier the BDC turrets are quick and accurate out to mid range (400yards to me). It takes a lot of changes in environmental conditions to make a noticeable change in POI differences at medium distance. For an example I just punched the numbers into JBM for the average MV of my M110 (since it's scope turrets have both). A 175 gr SMK @ 2530 fps. I threw in a 50 degree difference in temperature, 80% difference in humidity, and went from 28.00 in HG pressure to 31.5 in HG. The difference in POI is only a couple inches of drop...unless I'm doing something wrong. Ballistic calculators and I don't seem to get along.:rolleyes: I know that in most conditions I can turn the BDC to 4 and hit within inches of POA (not counting wind). Just another way to skin that darn cat. [/QUOTE]
