Rem. GB - I don't have a 15-22, so can't be precise in a response for the weapon, but as to the ammo, I have experience.
In my Ruger 10/22, it works most (ok, almost all) of the time. There are a few FTF rounds that have to be retried the second or third time, but no dump-box duds. Unlike Winchester M-22, which has a 3 dump-box dud per 100 round rate for me.
In my Sig 1911-22, they are not the worst junk, but so close as to be grouped in. I've had them actually break the bullet away from the brass on the ramp.
One of my range buddies has a Beretta Neos, and in that, the GB works like a champ. So, if that is what is available, I buy it for our range days, and when there is extra, it goes to the local Scout summer camp, which is still some 30K rounds short of what they will need for the summer. They shoot single round bolt action, so everything works.
It is, at least at Wally World, the cheapest round.
They are not as dirty as the Thunderbolts.
