This one is also very easy to do and it is working also great, decrease barrel heat very fast, and this one cost about 6$ to make it.


This is the main thing in the DIY project.

You then need to add silicone or plastic hose to the output tube, and you got ready to use barrel cooler, chamber chiller :cool:.

They sell this same equipment, with nice logo in Europe over 40$.

And other barrel coolers are about that same price, but DIY man can save money buy doing things buy him self:)

Here´s a picture of this machine, and you may see how i did this.
 
How exactly did your reduce the diameter to the plastic tube diameter?
 
Takin the measure of the cartridge, so it is about 12mm diameter on the outside of the hose on, this size cases are in 308win, 260, 243, 6,5x55, 6.5CM,and so on.
 
At the range where I shoot there's a power outlet right near the gun rack. I figured I could make a higher power version of the same idea.

Bought one of these air pumps for $10 shipped....

Then went to home depot and bought a roll of 3/4 OD Vinyl tubing (thin wall, 5/8 ID)...

The fitting from the air pump is a perfect fit inside the tubing, no couplers or clamps needed. The tubing itself is almost the exact same diameter as my bolt so it fits straight into the action with a pretty decent seal. Doesn't go into the chamber itself, just jams into where the lugs are.

It moves a TON of air!
 
this is pretty cool, were just talking about cooling our barrels between stages and increasing barrel life.
