I have never had good results with any Remington rimfire products, including their 597.
I am guessing that the gun will function best with the CCI Mini Mags, then it will be a tie between the Federal Value Pack and the Winchester SSHP, followed by the Blazer, then the Yellow Jackets, then the rest of the Remington "stuff."
For accuracy, CCI Mini-Mags will only slightly edge out the Federal Gold Medal.
I'm just guessing (based on my own experiences with hardware rimfire ammo).
I don't shoot the Stingers in most of my rimfires because the case is so long the bullet engages the rifling in a target chambered barrel. The Velicitors have the speed without the extra long case.
