[QUOTE="sierra22, post: 88499, member: 949"] [b]Re: \"Beyond Belief\" scope setup question???[/b] I seem to repeat myself, but here goes: To make BDC work in ANY conditions, simply make a ballistic correction card. Example: At x distance, deviation 20 hPa airpressure is 1 click. At x distance, deviation 5C ammo/airtemp is 2 click. It involves a bit of measuring equipment and work setting it up, but once you're done the BDC will work under any correction. Everything is on one card, works like a manual palm. This is actually what I find most interesting about LR shooting - changes in POI due changes in atmosphere. I only shoot one rifle and one load LR. It has been shot through the year with pious notes of results/atmosphere taken. The result is I have a pretty fair idea what happens, but it was a load of work and I pray that I'll never run out of my primer/powder combo. The most important data is the increase/decrease in velocity due change in primer/powder combustion, this the computer cannot help me with. There are more than one way to Rome. [/QUOTE]
