Bullets with holes drilled through the sides....

Sounds to me like the shooters equivalent of the "Platinum Vapor Injector".
I.e., Snake Oil.

They must cost a fortune to machine.
The gas is fed into the driving bands, so not sure how much "lubrication" it can provide...if it was into the gap between the bands, and accessed 360 degrees, I'd give it a positive maybe.
Muzzle brakes divert the gasses backwards, providing an opposite impulse to the ejected bullet/powder gasses. This might divert some of the gas to the side, but can't drag the barrel forward.
Maybe the hole in the base reduces tail end "suction", but boat-tails do this pretty OK too...and supersonic shockwaves would stop any real mass transfer from the sides into the "void".
Looks like a very elegant solution in search of a (multiple) problem(s).

Or it could be because the projectile is now lighter.
Looks like a gimmick to me. I have put thousands of .338 Lapua Magnum rounds downrange, and I really dont know how to improve much upon bot tail moly coated match bullets...
a gimmic for small caliber stuff. Maybe mortars and artillery, don't know.
- for stability you would want to make the nose lighter, not the base.
- lighter means higher V0, but lower sect dens so you would also loose speed quicker
- in super sonic flight, parts behind the front wave and the form of negative surfaces are basically irrelevant
- friction in the barrel is not a major issue once you entered the grooves. and you will not really improve matters by lubing it with chaotic powder gas and building up counter pressure in the front.
But always cool with new thinking. Although I would pay less for these so...
If I'm proved wrong and this is the sh.i.t in the future, I will make 200 push ups! Promise
Merry Christmas

So I've been out in the shop with my drill press...
Someone's always experimenting. Long ago good old George L. Herter sold the now long-forgotten Wasp Waisted rifle bullets for reloading. If they had been 1/10 as good as he claimed, we would now have nothing but Wasp Waisted rifle bullets!
Seen any lately? Not me.
