Reliability and accuracy are the two key functions that any undersized cartridge must achieve to make up for other shortcomings.
I carry a little 8 shot S&W 22 Airlite revolver in my aircraft survival vets for shooting small critters. After shooting every type of 22 LR ammo possible I found that the CCI stingers were the best from that particular gun for accuracy.
On the other hand two of my bolt action 22 rifles hate Stingers and just about everything else, while only likiing the CCI mini-mag hollowpoints.
For example in my scoped Norinco bolt action 22, ($60 at a yard sale) I can shoot 10 CCI Mini Mags into one hole at 25 yards and hit clay pigeons at 100 yards.
The other types of ammo, including the Velocitors, were making 1 inch (plus) groups at 25 yards.... from that particular rifle...
I find that after shooting 300 rounds of the 60 grain sub-sonic Aguila ammo in various firearms, that I wasted my money on poorly made ammunition that is lacking in accuracy and quality control.
