How Its Made:Remanufactured Ammunition (30 Pics)


It all starts from a trip to the range.
On the left is the bottom of the universal decapping die, which is use to remove the primers before cleaning. On the right is a resizing die, which is used to bring the case back to its original dimensions.
Using the press, the old primers are pushed out of case.
The dirty cases are placed into a rotary tumbler with some steel pins, water, and a bit of dish soap.

Here's some disgusting waste water. Change the water two or three times before it gets clear. This process takes an hour or two.
So nice. So clean. So shiny!
The cases are set out to dry overnight.
When the cartridge is fired, the brass case expands to create a seal against the expanding gasses. The brass will shrink when the pressure is reduced, but it does not return to its original size. The steel gauge will have a case fit flush when it is the correct size.
As with all good things, we start with the lube. This prevents the case from sticking to the die as it gets run through the press (on the right). The brass cases will receive another quick wash after this point to remove the lube.
The case is rolled on the pad.
Much better! The inner band represents the minimum length the case should be at, the outer semi circles represent the maximum. You can feel the difference with your finger.
At this point, all of the cases have been resized.. Next the case mouth is trimmed and deburred using the tools in the middle. The primer pocket is cleaned using the green brush, and the primer pocket (the hole on the back of the case) is checked using another gauge. If the pocket is too tight, it will be swagged to bring it into spec so primers aren't crushed during seating. If the pocket is too loose, the primer may fall out. A loose primer pocket is also a good sign the brass is too old and should be discarded.

Here you can see the difference between new primers and old, fired primers. If the finished cartridge is a match, this is the match head which gets the whole thing started. The gunpowder is the wood that sustains the reaction.

The brass case is placed in the tool and the handle is used to seat the primer. It should require a moderate amount of force to seat.
Here's what the case should look like with the primer.




Charges are measured out to within 1/70000th of a pound. The trickler on the right is used to drop one or two small pellets of powder into the pan at a time to get to this accuracy. Just turn the red handle slowly. A funnel is then used to pour the powder into the case mouth.

The filled case is placed in the press and a bullet is set on top.
The ram is raised...
...and we now have a finished cartridge!
The finished cartridge is checked with the calipers to verify the overall length before being put aside

FAQ: 1. It takes around 4-6 hours for 100 rounds. Different presses, such as progressive or turret presses, will reduce this time. 2. The match grade ammo costs around $0.30 cents per round 3. Total setup cost was around $300
