Golly! I really really hate it when I have to say something like this...
seeing how the kids and father all shoot light loads, i'd stick with the soft lead powerbelt.
MD is probably right in this statement. The Power Belt really is nothing more than a bullet shaped patched round ball and shooting that low velocity load - they should work better than a pistol bullet desinged to be shot faster - then add that to the easy loading for your son - Reluctantly I agree with MD.
For youself... I would change from the SW to a 40 cal 180/200 grain bullet. Either the Barnes 195, Lehigh 200, or even the Speer Deep Curl 40/180 grain.
just an opinion....
