Okay, let's discuss how a rifle can like a particular brand.
First, some questions....
1) Can any rifle fix variations in muzzle velocity?
Not talking about minor variations of a few fps that can be compensated for with a tuner,
but hefty differences of 40 plus fps or more? Not that I've ever seen.
2) Can any rifle fix asymmetric bullets? Those that are visibly distorted
due to issues during manufacture or damaged by rough handling on the assembly line.
3) Can any rifle repair unevenly seated bullets or sloppy crimps? Nope, not happening.
4) Can any rifle resize out of spec cartridges due to over/undersized brass or bullets? Nope.
5) Is any rifle capable of repairing a bullet heel damaged on the production line, before seating? Nope.
So if a brand has any of those issues, is a rifle going to like those cartridges? Highly unlikely.
In order to produce predictable and consistent trajectories, you have to start with uniformly well made cartridges.
Brand is not a guarantee of results. Even Tenex, X-Act, R50 will deliver crappy results
when the lot testing doesn't catch the problems and the run is mislabeled.
Finding well made rimfire ammunition is a problem.
A brick purchased last month produces spectacular results.
The same brand purchased this month throws strays and shows hefty vertical spread.
It's not brand, but cartridge quality that determines results.
The youngsters at the local range have stopped saying "My rifle likes CCI SV".
Why? I have a brick and a half left of what may be the worst CCI SV ever sold.
Someone tells me "all day long" with CCI SV, I have them show me, with a box of my substandard cartridges.
Garbage in = garbage out.
