Yes, someone that gets it. I always go with best paper results, rather than best chrono results.
Chrono has its uses. But not for load selection.
I don't know squat about this ladder stuff, but I can't imagine working up loads without a chrono.
I don't think he's saying he works up loads without a chrono.
Just that he doesn't pick the most accurate load based on chrono results.
I can't remember the last time I used a chrono during load development.
I usually only use one if I'm working with unknown powders with no data, just to see if they will give me the velocity I want.
Determining the velocity is pretty simple when using a Ballistic program at the range. If I'm shooting a 600 yard ladder, I look at velocity data for other powders I feel are close and dial to 600 accordingly. Adjustments are made and noted to the program's velocity figure until the amount dialed corresponds with velocity. After the ladder is done and I've finished the load, I know an estimated velocity. I then shoot steel at different distances up to 1 mile, adjust velocity in the program to give the actual data dialed...
Done.
