25 Round groups as Proof

[Fireflyfishing]

Here’s mine shooting 140 bergers. 15 shots each. Adjusted .1 mil from one target to the next.

that's probably when the internals on your scope crapped out.

Nope. I still use the scope on another rifle and it still does not wander.

I'm not trying to be critical of your test. It's certainly "valid", but I'm wondering in what real-world scenarios is it "relevant"? Are you trying to determine the precision potential of the rifle, or of the rifle + you?

Other than running a test like this, when are you plopping down to shoot 25 rounds straight?
Every barrel is going to wander a bit as it gets hot, and every shooter gets some degree of fatigue, even with a low-recoil rifle.

I would be willing to bet that if you strapped that rifle into some sort of mechanical fixture and had it shoot 1 round every few minutes, the 25-round group would be much smaller.

Maybe that's not what you're interested in, and that's fine, but then what is it?

I do this to understand that neither my rifle, not myself, are sub moa shooters. Not unlike many people in the world. I have an error factor (maybe not the best term) as does my rifle. I also have never been fond of cherry picking 3-5 shot groups and declaring ridiculous groups sizes.
When I shoot a 0.25 group and then follow it with another that has a center 1" further away I want to understand why. I also want to know what I and my rifle can do in a given situation when under less than ideal conditions.
Long story short, the real world-world scenario is to find the cone of fire for me and my equipment so I can better understand my limitations at distance.

What is your accuracy goal for 10 rounds?

I wouldn't say that 1.5" groups for 10 rounds is bad; it's the reality of shooting larger groups. Day-to-day variables will impact your results, so you can spend a lot of time and energy shrinking your groups only to have them get bigger because of a little bit more wind at the range on that day.

I dont disagree, but I have rifles that shoot much better is all. Rifles that are definitely sub moa for 30 shots which beyond sub moa im not all too interested as you get diminished returns. 1.5 is plenty for a hunting rifle.
