Harold Edgerton did some experimenting with this type of projectile at ultra high velocities back in the 30's I believe. I also saw some experimental projectiles like this but with a cylindrical carbide insert, very sharp edge, used to defeat body armor. This was back in the early 80's. Seems nothing is new under the sun.
If I remember right, CCI loaded something like this in a handgun round years ago. Theirs had a little cap on the back instead of a sabot. The short test done on them was published in a popular gun magazine and though I think they only tested accuracy and not terminal performance, their remarks that stand out in my mind were ...even at 25 yards they impacted 6-8 inches higher than any other load...
Longer ranges might get funny with the wind whistling through the "hole"...

You are correct, Roger. It was nicknamed the "cookie cutter", and on the examples that I saw, the "mouth" in the carbide ring resembled saw blade teeth.

Thanks for the history guys, but I am BTT so that perhaps someone has some current experience with these bullets.
500grains:
I plan on using them on deer and hogs, but they claim significantly flatter trajectories(for obvious reasons, the wt. as you pointed out) so they might be interesting for longer shots than one would normally consider .45-70 range.

Sorry, no experience with "holey bullets, Batman!!"
But this idea was tried in the late 1800's or early 1900's when smokeless powder was a new technology. The idea was abandoned, because it gave poor results in almost every way one can think of. Low SD, low B.C., highly susceptible to wind deflection, poor velocity retention, and poor penetration. Will the new ones do better??Here we go again!!
