RS ammo using AS principles?

The quote.

Basically this manufacturer is putting holes in the back of the rounds (boat tail in this case) that is supposed to be "providing lubrication between it and the inside of the gun's barrel".

Meanwhile the operating theory behind 5.95 v. 6.01 v. 6.03 v. 6.23 is the idea that air around the BB is stabilizing it in AS.

At least I saw the (possible) connection... maybe I'm just seeing things again

Balistics would be interesting. I think the idea is to decrease the surface area of the round to that is "swedged" in the barrel to engage the rifling. Between decreased surface area and decreased weight from the holes I think its a toss up. It would probably work better with a boattail in RS. I could see this going either way balistically...

High velosity, low mass. From Chey Tac:

Last page: .50 BMG 670gr v. .480 Chey Tac 419gr
.50 @1500m: Vel - 1067 Energy - 1668
.480 @ 1500m: Vel - 1520 Energy - 2150

But yes, when it comes to AS, since we're stuck with spheres, more mass = better.
