It tumbled and yawed I believe because of its centre of gravity was close to the base of the pill. Its tendancy to yaw and tumble "could" well be recreated by using a 7.62 pill with a similar profile/scale to the M193. Unsure what the lower velocity will do but a naturally unstable projectile is just that so maybe worth a go. 110gr barnes hehehe

The cannelure on the M193 causes it to break apart when it tips over, if speed is sufficient. The change over I believe was due to concerns about defeating body armor - M855 has a steel penetrator.

Back on topic, what about a 110gr V max? Yay/nay?
