There's a certain mystique to 1,000 yard shooting to those who haven't done it. It's not a big deal. Shooting 1K is just like shooting 600 except you put more dope on the scope. Don't let it get in your head. You don't need to master some esoteric set of skills at 600 before you can graduate to 1K. If you were on a 1K range and making hits at 600, you'd just dial up some more elevation and do all the same stuff.

I understand you don't have ready access to 1K and no plans to pursue it for a while. I just want you to understand that 1K is not some magical unicorn that only the select few ever get to see.
