played with it ...
there are some upsides to it.
Without the groove setting a minimum length, it is now possible to cast lighter, higher velocity bullets.
They do seem more accurate, and behave a bit more like jacketed.
And while more of a rifle advantage, the BC is higher without the grooves acting as air brakes.
