I used to have a .177 LEM mould, could never get them to shoot in my spring powered rifles but would be interested to try them in my pre-charged rifles. Unfortunately I sold it before pre-charge was really a thing that was accessible for me.
Closest I could get was a .22 buckshot mold that does make a fairly good round ball load as long as I am careful with the sprue cutter.
That's just too cool...endless pellet supply.
