How do you guarantee it tumbling tho and not just upsetting a bit and pissing off in a different direction in the animal.

Wee bit out of my league here but, when the 5.56x45 was designed and tested before the "Nam" they were relying on the tumbling effect to cause massive wounding, now im pretty certain that the projectile was a 55gr pill called M193, Changed when the 556x45 became a Nato round in 77 because It was apparently inhumane due to the massive wounds it caused in comparasion to its small size. 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?
