hello, this ones for the airforce airguns nerds like myself. if you have not purchased the ring-loc top hat gizmos you reeeeaaaaalllllyyyyy need to...I recently put the 25 cal barrel back on my talon P and decided I wanted to shoot the JSB King pellets at about 900 FPS, so I did that with the original .232 top hat, no problem at all. pretty consistent, accurate, just as you would expect. then I put on the .166 top hat, and tuned the gun back up to about 900 FPS, same accuracy as before (wouldn't expect much deviation there) the shots may be more consistent, I haven't done a shot string yet, but what I noticed the most is how much quieter the gun is now. it makes total sense, but I was shocked at just how quite it is now even without a moderator (the one I had blew up) before I would describe the gun as sounding loud and a bit sloppy, like a very poorly tuned regulated gun, just a puff of air dumping down the barrel, now, however, its a lot quieter, and the sound is much more crisp. not quite well tuned regulated gun sound, but a lot closer. I wanted to share more today but the winds are like 20 mph or something crazy right now and it's really pushing that King pellet all around but hey, it sounds better now! 
seriously tho if you have any Airforce small bore airgun that's compatible with the top hat system, you owe it to yourself to try it out, they really undersell it online.
