I had some from before the madness. I was very impressed on how well they smacked rabbits in the yard from a pistol. None of the bullets exited on more or less frontal body shots but the rabbits dropped right there. I haven't shot them for accuracy, I just planned on making corrections on pests until I got hits. The first shot I was lucky enough to put the bullet where I wanted and have used the same correction since.
In a rifle I have shot them mostly on paper. With a 50 yard sight in for high velocity rounds, the subsonics hit the same point at a little over 25 yards. The few shots I have taken at something other than paper has been a couple of red squirrels which they dispatched with aplomb.
I have shot the Fiocchi subsonics more often. They have the same point of impact as the CCIs in my guns. Their performance on game has been much the same and I will pick up more if I get the chance. The great part of these rounds is they are pretty quiet. For shooting around the house they can't be beat if the wife is working from home and on a conference call. It seems that a pest that needs shooting always pops up when it is not advantageous to shoot it. With the subsonics that is much less a concern.
