99% of my rimfire ammo use is plinking,,, so accuracy is not mandatory.
That said,, all brands of ammo seem to work for me.

I think I have had under a dozen FTF's,, out of 20,000 rounds. (that is over a LOT of years)

In the case of those FTF's,, I feel the gun was in need of cleaning when the FTF occurred,,,
