You can't bring back something that never was. Cannelures are not used to form a "shelf" anywhere on a bullet, and neither the 9mm Parabellum round or the .45 Colt Automatic Pistol round originally had a cannelure.
Speaking of the case not the bullet, both .45 ACP and 9mm Luger ammo wwere available with the cannelure, its even mentioned in the manuals for the 1911.
AMMUNITION FOR AUTOMATIC PISTOL CALIBER .45, MODEL OF 1911—BALL CARTRIDGE.
The components of the ball cartridge consist of cartridge case, primer, powder, and bullet.
The cartridge case is cylindrical and is made of brass. It is provided with a cannelure to prevent the bullet being forced down on the powder.
I have a partial box of vintage 9mm ammo with the cannelured case, and I think I still have some vintage .45 ACP cartridges with the cannelure.
The cannelure rolled deeply into the case body serves no other purpose than to form a internal shelf.
