I haven't listened to that one specifically but what I currently do is pretty similar to Miles. It's definitely informed by the tests he spent his spare time and money doing, using Hornady's equipment.
There's lots of guys at the top in PRS/NRL and even F-Class who do similarly. I think Tate...

With something I'm very familiar with, like 6 Dasher, I just pick a load based on experience. I might only load 20 to confirm, or depending on circumstances I might load a couple hundred. I've competed with three loads out of my...
