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...
I won't claim to have "the" way, but I'll tell you what I do.
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...
I'll use a ladder occasionally to find pressure and velocity for a new combination (usually loading at the range instead of at home).
I don't use them anymore to find accuracy, personally.
I know of some guys in the Paradise Valley who like to go that route. Apparently they have trouble keeping sheets in place prior to pouring due to wind. Did a friend’s basement and garage that way. Never been involved myself.
I never especially favored the feel of the Jewell's, even when they were THE precision trigger for 700 pattern actions. They have always been known for being fickle and fragile, but I never gave them a chance due to personal preference regarding the feel. Just not my thing, lots of guys shoot...
Anything that fits (BR, Dasher, Creed's, 243, etc) goes in Alpha boxes. If it's Alpha brass they come with it, if not I'm happy to pay the $8.00, they're my favorite.

Most of my 223 practice ammo is in ammo cans.
My 6 Creed PH2 has shot phenomenal. The performance per dollar is hard to match. I prefer the Tikka actions but for NRL Hunter it made more sense. Tikka is supposedly releasing a 6 Creed themselves this year.
I have no personal experience, nor can I recall someone I know telling me about using them.
I don't doubt they'd probably work, but I'd personally ease into them and see how it goes on a tag of less importance. They won't hang on to velocity as well as the match bullets, so I wouldn't stretch...
Shooting volume is one reason I favor the smaller rounds. I shoot 80-200+ on a typical range day. When you factor cost and barrel heat, it's much easier to do when burning less powder. Not to mention, almost no one wants to shoot 100 rounds of magnum from a lightweight rifle in one sitting...
Some guys get religious about it, which can certainly be a turn off.
I bet that works :)
When in a position where people are asking about hunting rounds, 90% of the time I recommend a 6.5 something.
For my guns? Used 88 ELD's in a 22 Creedmoor, was very satisfied with their terminal performance. They could group a little tighter but shot well enough to not limit my range. Plan to give the 88 TMK's a try as soon as I can get my hands on them.
For your 8 twist 223, I'd start with the 75...
