There is no such thing a any one breed of .22LR Ammo that is good in any Brno or any other rifle.
Every Rimfire will work best with what ever ammo IT likes. Two Brno's, same model. same age, same everything else will work better with what it likes.
You don't really need to trick a Brno Model 2 for example to make it accurate unless some reason it didn't shoot in the first place other than finding the ammo it likes.
I have shot my standard factory 1965 Brno Model 2 in a State Title Target 200 Yard competition against 40 other competitors using Custom Grade Rimfire Rifles worth many thousands of dollars and held 6th place most of the day.
Target wise it's best ammo was Eley Black Match (expensive) but very close to it is Lapua Centre-X much cheaper and that's what I used for the competition. Hunting it's the old version Winchester PowerPoints BUT the new version isn't near as consistant.
Old story with ANY .22LR is buy all and every breed you can find and test them all, one will shine above all others. If you change manufacturer of ammo then clean the bore to remove the different wax coating but other than that I do not clean a .22LR for any other reason.
