That's pretty damn neat.

Do you have a 300 Black Out you could stick in there?

Tell me more about the bottom round. The thread title alone had my interest.


Now you have my attention.

Pretty sure a .223 and a .300 are going to have a different diameter round and won't fit in there.

The area between the step where the case ends, and where the rifling starts.

Neat!  Thanks for posting that.

I agree w/ person above - it does not look "shot out."

On the other hand, the proof is in the performance - and it sounds like the barrel was not performing it's best any longer.

Some will, some won't.  Depends on the bullet profile.

Due to the fact that the case is shorter, you can chamber a 300 BLK in a 5.56. There have been several cases of people exploding their guns doing just that.

Man.....that is a really long bullet. I wonder what twist you need to stabilize that?

Perhaps something on the order of 24 TPI screw thread. It'd be a bit dicey getting the rifling to bite at any kind of useful velocity, though

This!!! 

I was aircrew in the USAF and flew on the AC-130U Spooky Gunship.   We managed to get a few non-serviceable 25mm Gatling gun barrels from the guys that fixed our guns and we cut them down as below for attachment to retirement plaques, etc.  We used a chop saw and it took forever, damn those 25mm barrels are tough!  The 25mm round in mine is a fired case with a turned wood projectile painted to resemble an HEI round.

A little more powder and a little shorter barrel and that might work.

Damn that looks cool, thanks man.

For those without a mill or barrel to destroy, Sheridan makes a case gauge like that.

I wonder what kind of wound such a round would leave if it tumbled in the target.

The problem is the recoilless nature of the round lacking a proper backblast area tends to injure the firer, impressing upon him that homemade Gerlich guns are expensive to receivers and fingers, if not eyeballs.
