I really like the fact that I have a chronograph

You can shoot through your chrony at 1768 yards?

Maybe they weren't woodpecker holes?

Why??? would you want to shoot through your chronograph at 1768 yards?

No clue at all, you should read the post that I quoted asking why they do it. Post #18

To calculate the BC of a projectile?

I think (not an expert here) that one would need two chronos to do that.

I don't think that you would need to have a chrono at nearly 1800 yards to arrive at a decent calculation, unless it is some really high velocity cartridge and one needs a subsonic velocity to calculate BC?

Yes. I can buy that. But don't most bullet manufacturers have that information available in their reloading manuals or on their web sites?
I have two chronographs, but I don't think I want to put one at 1800 yards either. That would be a little scary for me.

Some people make their own projectiles using swaging presses.

Personally, I don't think the idea of using a chrono at about one mile is practical. Not sure why someone would do that.

The only problem with chronos:



Not what I intended.

Or at least knowing the high & low numbers. It only takes one flyer to miss when hunting.

Yeah. One of my uncles always blames missed shots on load variances too.

To get any meaningful data for distance/load calculations you certainly would. Any variance at the muzzle would cause an exponential variance at distance... so without knowing exactly what velocity was at your near distance.... your distance chono reading would be rather worthless for load adjustments.

Unless... it's just a curiosity thing... but I don't see how it would be at all meaningful for anything else without an accurate muzzle velocity.
