I’ve been shooting them in the yard out of my Marlin 39. At 25/30 yards they’re not bad. I was using the cci shorts but the accuracy wasn’t good out of the 39, Both are the 710 fps. Only reason I had either of them was the shorts I bought off GB for a price I couldn’t pass on. And the quiets are the only 22’s my local gun shop has, I’ve accumulated a little stash. I wound up selling and trading all my shorts.
I will say that they aren’t very powerful at 710 fps. But good enough for starlings.
