Actually, the conversations with 3 mould makers and some experiments are what led me to believe that you cannot mould adequately anything under 0.25" cal. (actually, the diameter at the thin edge of the skirt is around 0.260").
As long as a good alloy is used that incorporates some Tin, it is quite possible to make the skirt using a hinge-pin mounted punch. The mould's temperature is somewhat sensitive, but it is not harder to maintain, than the normal casting of Loverin style bullets.
A peculiar offshoot of all this was the current availability of shotgun slugs that are nothing but scaled UP diabolo pellets! ROFL!
Sabots are interesting, but the real application of sabots is in the use of non-conventional projectiles; in that sense, some flechette experiments proved VERY interesting, but not yet applicable to the current state of the art rifles, nor targets. JMHO.
