Re: John Burns-Best of the West- equipment
How many people have any clue what the difference will be from ther baseline zero to 7,000ASL? How many people have the equipment, and know how to adjust for the difference?
Given a a 30cal 178gr with a BC of .525 at 3,000fps, there is less then one MOA difference between SAC zero and standard conditions at 7,000ASL, at 600yds. Thats about as big a difference in pressure you'll get under all but the most extreme conditions, and yet it acounts for less than four inches. 99% of the ones who jump up and down about being able to adjust for the conditions with there 1/4 MOA turrets, have no clue how to do it. Therefore they are no better off the someone with a BDC.
Unless your prone to switching loads, travel all over the country,(even then they can still work), or seriously shoot past 7-800yds, (even then they can still work), a BDC set up for your load and the area you hunt, can work. Is it the most ideal? Maybe, maybe not. But it will work.
