The first time we went out matey shot a 2" three shot group with Hornady Match ammo.

Interesting Marky, do you have a short..ish barrel. My Speed was 2700 for a 26 inch barrel. Verified with drops and data out to 600 yds for 1/2 MOA on a good day, but usually "blew" out to 1 1/2 with wind. Still maintained 1/2 MOA vertically
Dont take any of the critique, we have given, the wrong way we just obviously do things differently.

Here's the video and corresponding thread I talked about earlier

Interesting video @The Claw, tx for posting. He makes several really valuable points about choosing the middle of the node for extra security. Something I've seen time and again at Seddon. Typically at least one of the days during nationals week, it turns southerly and temps drop. Guys who are at the margins of nodes (the speed demons) suddenly find themselves with massive vertical issues.

The other comments I found interesting were his statements about horizontal dispersion at long range due to seating depth. Probably more of an issue with the VLD type projectiles.

It would be a cool exercise to run a blind comparison between a long range ladder and a short range chrony only type node hunt, and see if the results differ. I suspect they will be very similar.

My over-riding comment is that in order for ladder tests to be of value, the shooter better be shit-hot and able to shoot to very small margins of error
