[QUOTE="Darryl Cassel, post: 23029, member: 34"] Ric Heres the variance of the 30 degree to 55 degree change of temperature along with the 5000 feet elevation up to 10000 feet change. At 50 degrees and 5000 feet elevation at 1000 yards, I would need 16.1 MOA in my 338/416 Rigby At 30 Degrees and 10,000 feet elevation at 1000 yards, I would need 15.4 MOA to cover the same distance. We are talking about 7/10 MOA or 7" at 1000 yards. Not really a MAJOR concern if your spotting for someone or have a spotter for you. This would change though if someone were shooting a bullet of low BC as compared to what mine does. As for the ballsitics program. I was refering to the small computers that are available and not to a tiny little hand held. Some of the very small laps that you can hardly use the small keys would work for you. Later DC [/QUOTE]
