Default Good trajectory chart

What is a good source for wind drift/trajectory chart for different calibers? I need a starting point for several guns and understand they are approx.. Going to shoot them on paper this weekend to get actual drop out to my max range. Bored at work and need something to study over!!!

FWIW, I ran some "known parameters" through Slo-Pok's link and the results closely matched what I have verified for my 204R at the range. I have played with at least one other program that was not even close to what I have experienced. YMMV

Ballistic charts/programs are kinda like the "Pirate's Code", they are more like a guideline. Atmospheric conditions, elevation, & a host of factors affect a bullets trajectory. Unless the conditions you are shooting in match the conditions used to calculate the ballistics chart, your trajectory will be different. I'm a lucky enough to have enough property to shoot to 1000 yards, so I just shoot @ the different distances & see what my trajectory is. It's more fun than reading a chart & more accurate as well. Most of the time the real trajectory is much different than the chart.

Thanks for the info. I downloaded BulletDrop for my I phone and is very similar Biggameinfo. I shot my 22-250 out to 400 yards yesterday to compare it and it was almost identical to the app I downloaded.

I will use it for a reference/starting point but I always shoot to make my actual trajectory charts

Use a Sierrra V 6 suit myself and found it does what it says on the box and a good book on reloading info as well
