Saw this today on reddit:
http://www.gizmag.com/compbullets-faster-with-vents/20806/



This part was interesting:

First of all, when the gun is fired, the vents supposedly allow the propellant gases to go through the sides of the bullet, providing lubrication between it and the inside of the gun's barrel.
It would appear that RS is going the direction of AS (assuming that this principle works); while we in AS have been trying to go the direction of RS... discuss!

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

There is no space between the bullet and the barrel. If there was.... oh wait there was... that is what a muzzle loader is.

You don't want any space between your bullet and your barrel. Because if you do, you will loose pressure as well as any kind of accuracy that you would have.

It would work pretty well on the boattail rounds I think. Keep the boat tail nice and centered using pressure. In theory of course

That is not all they are trying to do. This is another way, be it absurdly expensive, to prevent muzzle flash and potentially stabilize the weapon. I think you are looking into things. The only way you would get the bullet to twist properly is by forcing it down a barrel that is actually smaller in diameter than the bullet. This forces the bullet to slightly deform into the rifling and the barrel can at that point provide the necessary twist for accurate shots. This technology basically a solution looking for a problem. The vortex or cushion you are referring too is more applicable to blowgun technology.

I can see the muzzle blast really screwing up the round as it comes out of the barrel.

Like mateba said, this is just causing a problem for something that hasn't had a problem in a while.

It just looks like some one put a bullet in a drill press and did some drilling.


I seem to remember seeing these same things a year or so ago, and it was a spoof about Barret making the 416 or something.

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...

When you are shooting anything...... if it hunting, target shooting, or for personal defense, you are going to want a heavy bullet not a light bullet.

A heavier bullet will "buck" the wind better than a light bullet... as well as hit the target with more energy than a light bullet would. More mass will equal more knock down power.

This is the same principle that you see in any kind of shooting.
