So here's my question, for those of you with sophisticated computer programs that tell you how much elevation and windage to crank in based on distance, wind, Coriolis effect, and phase of the moon:

**how many inches will a 130 grain Sierra bullet traveling at 3,000 FPS at the muzzle drop from 100 yards to 200 yards?**

I know this is not a sophisticated equation. I am getting decent groups at 100 yards with my current load, and I want to begin shooting at 200 yards, but don't want to fire a 200 yard group to determine how many inches I need to come up, and I know there are computer programs that will tell a shooter how many clicks to crank in.

So what say you? How many inches should I crank in for a 130 grain Sierra soft point boat tail bullet that leaves the muzzle at 3000 FPS, if I want to hit the bullseye at 200 yards too? This should be a pretty straightforward computation, I should think.

If I'm successful at this, I hope eventually to reach out to 500 yards. Small potatoes, I know, but there you are.

Thanks.
