Sadly, it's not about label preferences.
Nor is it about brand preference either.
Such thinking indicates a lack of understanding
of the process of manufacturing rimfire ammunition.
Facts to remember:
No rifle can fix poorly made ammunition.
No ammunition can fix a poorly made rifle.
No two rimfire cartridges are identical.
Components, chemistry, quantities, tolerances
vary moment by moment on the assembly line.
Some days at the factory are better than others.
What rifles "like" are uniformly well made cartridges
with consistently similar muzzle velocities.
Any variations in quality, velocity, result in trajectory differences.
If you believe all cartridges are identical as they roll off the assembly line,
well, then, I suppose brand preference is a plausible explantion of results.
When you understand that variations in components/assembly occur
then rifle preference by label is no longer a viable explanation.
You now have to look at cartridge quality as the cause of accuracy problems.
CCI is not in the business of manufacturing benchrest cartridges.
All it's 22lr roll out of the same machines, run by the same technicians,
using processes established in the last century.
That includes priming application by punch plate and squeegee.
Watch the factory tour videos.
Dropping, dumping, tumbling in drums are not how match bullets are handled.
CCI manufactures sport shooting cartridges.
Short range, off hand they do the job.
For punching center at 50 yards off the bench,
there are better options.
CCI Pistol Match, Green Tag show the same results as CCI SV
from my Lilja, and Shilen barreled, CZ's.
Chrony numbers show the same problems with velocity spread
and visual inspection of the cartridges show the same indications
of rough handling on the assembly line.
It appears we are paying extra for packaging and label differences.
