Almost. I have a 20 Bobcat. Just a 20-222 made into an Ackley. Little more powder capacity and brass lasts forever. Kevin Weaver (Weaver Rifles) created it and does a lot of 20 caliber ctgs.
Pro, accurate, long brass life, brass is available (including Lapua), easy to form cases, fast.
Con's, need a new die set (Kevin stocks the 20 Bobcat dies).

It almost looks like you can make the Bobcat brass from .223 in a single pass like a 6 SLR...
