I understand your views.
They were mine, until I had a problem.
I had read that every rifle likes what it likes, so I went looking
My 455 Lilja absolutely "loved" Wolf ME, made by SK.
Sub inch groups consistently, 100 yards off the bench, box after box.
Absolutely amazing results....I found the brand my rifle "likes".
Until it didn't. What happened? Ran out of that lot number.
Next case of Wolf ME was 1.5 to 2 inches for 5 shots at 100 yards. Strays, hot, weak cartridges.
Same brand, same label, different lot number.
The cartridge quality was not the same.
So I went looking again. RWS R50 was the next label that produced consistent trajectories,
for a couple bricks, but the next brick from the same case, didn't. WTF?
The same thing happened with SK Pistol Match, then Eley Match,
followed by CenterX and Midas+ and then Tenex.
All those different brands produced consistent trajectories,
but then open a new brick, and the results went downhill.
Label meant nothing. If the cartridges lack tight muzzle velocities
and uniformly well made cartridges, label is not a guarantee of results.
My rifles don't care about who makes the 22lr cartridges.
Only that they are made to saami/cip specs,
have tight mv's and minimum cartridge defects.
Any brand that does so, produces similar results at 50, 100 and 200 yards.
I documented the chrony numbers and targets for 4 years.
It wasn't brand name that the rifles needed, it was cartridge quality.
If you believe that all cartridges are identical as they roll off the assembly line,
then go ahead and "find the brand y'er rifle likes".
But if you understand that rimfire ammunition is mass produced,
subject to variations in components, chemistry, assembly and technician input
then you know that no two cartridges are identical and quality varies moment by moment.
What comes off the assembly line in the morning
is going to be different than that made later that day.
Find the brand doesn't work.
Find the cartridges that are made properly, does.
That's why even cheap bulk ammo can produce amazing results on occasion.
Those particular cartridges produced similar muzzle velocities
and were uniformly well made....until you catch an average quality cartridge, again.
