Re: sierra ballistics software accuracy?????

I ran this thru RSI's Shooting Lab software.
You didn't mention one parameter that mine wants to know and that is relative humidity. Shooting Lab defaulted to 78% and I just left that alone. All other parameters were as you specified.
Here are the results:

250 yards: Drop is 12.82 inches and path is -2.51 moa
500 yards: Drop is 58.94 inches and path is -8.68 moa
750 yards: Drop is 154.98 inches and path is -17.09 moa
1000 yards: Drop is 328.60 inches and path is -28.71 moa

Hope I did it right. First time I have used this software. [img]/ubbthreads/images/graemlins/smile.gif[/img]
I just got it with my new CED Millennium Chronograph. Actually I have had it for a year and a half, but I've been so busy with work and all it's going to get it's first range test either tomorrow or next week. Sad huh?

A man who has nothing which he cares more about than he does about his personal safety, is a miserable creature, who has no chance at being free, unless made and kept so by the exertions of better men than himself."
