The Nosler manual has ballistic charts. As does the Hornady manual. If you don't have these we would have to know the velocity.

I have checked with LoadBase; assuming that you have a sight height of 2 inches, it will be:

200 yds - 3"
350 yds - 20"
400 yds - 29"
525 yds - 60"

Do a web search for JBM Ballisitics and use the "Basic Trajectory" model to find your own data with any variables that you choose. And the best part is that it's FREE

The problem is I have a 300 yard rifle range to shoot at. Where I go to "compete" is out to 525 yards. When I load all the pertinent info into a ballistic calculator I get a set of numbers that doesn't correspond to where my bullets are actually hitting at 200 and 300 yards. So I need a calculation where my bullets may hit at the longer ranges. Since the calculator is off by a few inches at 300 yards it is tough for me to trust it at 400 or 500 yards. I guess I'm looking for a shortcut. The bottom line is I will need to actually shoot the ranges to get the correct trajectory. That is more fun anyway.

That is the correct answer. No ballistic chart is perfect.
