Annealing

I'm really getting into that Hornady Pod Cast. The one where they did the visual on powder through the barrel was eye opening
Couple of the guys did mention that they don't anneal each firing. I have no hard data to prove or disprove that, but my brain says each time or no time to keep it consistent?

I would say each time. Each time you fire and re size. The brass gets harder. So you never have consistent brass. That’s just me thinking about it.
Yes sir. So far, I have not noticed a change in POI, ES or velocity on my X-Bolt in .308. I've been running SP Alpha OCD and have 6 loadings on them

I annealed some 308 cases and did a pressure test seating bullets and you had to anneal nearly 30 seconds to get a different seating pressure.
These were Winchester cases.
Not annealed and fired 2 times the seating pressure was in the 18-20 psi area and annealed it was in the 40 psi area.
Necks were brushed after annealing and before full length sizing.
Then lube was Qtipped out of cases and then chamfered and then brushed and Qtipped again.
Lapua 308 cases did not show much variation in annealed vs multiple times shot. 85 psi area for that brass
On paper if i do not anneal each time my groups suffer.
If I have a shoulder bumped back farther than another my groups suffer.
If I am happy with 1 MOA I can skip some measuring and annealing.
I am not happy there.
