I wanted something to test it when it arrived. Measured head size of various pellets the Crossman premier domed

has perfect head size and a very thin skirt of lead. Using a wire draw plate I use for pulling wire, found the hole of the proper head size, dropped the pellet head in and shoved it through with a punch. Making the skirt thinner. Kind of like a reverse swaggering. These should work I'll let you all know.
 
You may try an experiment with the first Ballistic Products 0.210 round balls by using 2 flat cross cut files or flat rasp files squash apply pressure and roll them sandwiched in between top and bottom to crosshatch texture the entire outsides might shoot more accurate never hurt to try like golf balls. Don't laugh it may work!

If you are going to size them get the next size up 0.220 but must be deliberately loaded a certain way for sure.

You can also try the lead free pellets if you are sizing them anyway if you want more speed. Light plastic sabot types may work too. These are Pretty expensive though.
