I don’t bother trying to keep my brass headstamps separate and if there were any significant difference between brass as far as neck cracks or service issues, I’d think I (and many others) would have noticed.

Grouse, I was thinking about this more and I’m surprised you haven’t noticed a difference.
I was speaking in terms of a difference in the brass lifespan, Randy.
I certainly HAVE noticed that different brands have different weights, thicknesses, and therefore capacities. In a .22-250, this is not very noticeable as with most modern powders, you’re only filling roughly 60-80% of the case at most.
With a .223 it’s painfully obvious because even middle of the road loadings are compressed loadings and with some cases you can’t get near the max loading because the powder is falling out of the case.
I’m sure it all matters, but how MUCH it matters is a question for the individual shooter. I reload to achieve a certain level of accuracy over/above factory ammo and for volume/cost reasons. I’m not trying to break world records.
In the dog town, there are so many things that contribute to me missing that the inconsistencies imparted by mixed brass don’t even register on the scale, for me at least. All of my go to loads and rifles shoot sub MOA as a real 5 shot average over at least 5 consecutive groups. It might only be .95 MOA, but sub is sub.
Now what that means out in the dog town at 95 degrees with a variable wind blowing, heat mirage, moving dogs, bugs landing on my face, sweat running in your eyes, an imperfect field rest, etc is that the ammo is now one of the lower factors on the totem pole for me.
