Re: rocks at 2200 yards with 338 lapua
-The reason I mentioned the iPod is because I use an iPod with Shooter installed. All my ballistics come from that unit while in the field. I choose this method as I can use the iPod to take pictures and vid and record my DOPE. All of my info is that unit. Anyway... Is it better than a camera? For your price point, I would say no way. It is better than many cameras in the $300 range , with a good scope. I assume you have a high end spotter like a Leica or Swarovski for spotting shots, if so, see if you can use your iphone or borrow an iPod to see if you like it with the scope. You will know right away. Again, my guess is the camera will be better with a good zoom doubler etc.
-Your progams are fine, no need to change.
- G7 is the BC measurement I was refering to, not G7 from Gunwerks. G7 BC is what many LR shooters use in place of G1 as it tends to be more accurate. I would spend some time playing with the G7 BC of the upper end LR bullets, even custom brands. The 300 VLD is another 50 points better than the OTM I think.
As far as the numbers you are giving I didn't ask other questions to clarify if the Barometeric pressure was corrected or Absolute. If corrected I would have to have the altitude too. I just ran the numbers as corrected BP and left all the numbers the same with variation being the Bullet design and BC.
Perhaps some of the highly skilled and experienced crew will be chiming in as well.
