View Full Version : Inceptor ARX Ammo

Stumbled on this while perusing ******* on a similar ammo topic.

The concept seems like a win. A 9mm 74gr round, moving at 1440+ FPS, from a 4 inch barrel. The only draw back, I saw, was the penetration on non-target material, ie: walls, windows, steel.

Here are a series of penetration test. The last one is a PR vid from the developers.

The bullet does not separate or mushroom. It acts like a propeller, using spinning centrifugal force.

In a couple of the tests, you can see the bullet imparting spin on the ballistic jell wound cavity..

Notice how they are going for the "modern firearms laws".
No lead in bullet = "green" ammo
No hollow point so it opens the military market.

Not for me but interesting concept.

Gives a new meaning to getting screwed.

Too many words....

All bullets 'dynamically transfer directional and rotational energy.....'

What they should be telling us is if and how the bullet shape (cutting edges) affects the wound channel.

I think things may be a bit overdone for marketing reasons. If you consider that the American twist rate for a 9mm is about 1 turn in 16 inches, that bullet is only going to make a single revolution as it passes through a chest cavity. That is hardly a propeller churning through a body. Even the European twist rate of 1 in 9inches isn't going to make much difference. Sure a bullet is spinning like crazy when it comes out of the barrel, but you need to look at the number of twists made in a foot, rather than the rpm.

I had the impression that the way the bullet is formed, it may cork-screw by design after leaving the barrel??

If it does spiral, it probably does not help accuracy, but at 20ft who cares..

If you stop this video at the 13 second mark, you can see the cork-screw propeller like cavitation action.

In most of the gelatin videos, the bullets tumble making them (most likely) similar performing to FMJ.

Not impressed.
