Long range target shooting and physics

This discussion thread was locked as off-topic by krispos42 (a host of the Gun Control & RKBA group).

What a beautiful and challenging undertaking. There is so much to take in and calculate, to shoot accurately. You have to account for the wind speed, temperature, humidity, barometric pressure and elevation, along with your perticular cartridge characteristics( weight of projectile, ballistic coeffecient and velocity). and if ONE of those factors changes you have to recalculate everything to get that perfect shot. Velocity of the bullet always slows after it leaves the barrel(obviously), which causes the biggest variation-goes slower, drops faster- with given atmospheric conditions there may be a 4 inch drop from 100 to 200 yards then a 15 inch drop from 200 to 300 yards. Of course you have to do less math if you are happy with just hitting the broad side of a barn, but if you are trying to put 3, 5 or 10 shots into a 1/2 minute of angle bullseye then it's physics applied over vast distances. You want to have the least amount of body movement from shot to shot and you want to fire the rounds before any of the conditions change. Bolt guns and good semi autos are best. Just hope my AR doesnt get taken away, it's one of the most accurate I've handled.

3. Locking

Sporting and recreational discussions about guns belong in Outdoor Life Group, and that includes long-range target shooting.
