[QUOTE="goodgrouper, post: 59684, member: 2852"] Thanks Dantec. I spent several hours yesterday inputing a gun's trajectory into about 12 different ballistic programs and they all came up slightly different! I was out shooting the day before yesterday at my gong at 1000 yards, and I had my laptop there and my chronograph. I used sierra infinity to input the data directly from the chronograph into the MOA on my scope. Then, out of curiosity, I went up 1 more minute than what Infinity said and my first shot hit at 3 o'clock and missed the edge of the gong by an inch. Why was Infinity off so far? I have shot many guns at 1000 that were off a little too, so I know that it wasn't just that gun/bullet combo had a lower bc than what is published. It seems to me that Infinity is just a little off at longer ranges. So I inputed that same gun into 12 other programs yesterday, and they all had a slightly different number for come-ups. Infinity said come up 19.2 Moa, and I was looking for a program that would say 20.2 Moa as that was what I actually had to use to hit the gong at 1K. Dave Kings program, Pejsa's program, and Exball were the closest to 20.2 Moa, so I am deducing that they might be the most accurate. What is everyone's feeling of these findings? [/QUOTE]
