Home Forums Hunting & Shooting Predators and Varmints Water Cooling ?

I've amalgamated a few ideas into very simple and cheap system that works. I would also like to thank the members who PM'd me with ideas, info and support.

The funnel was A$3.95 and the 10mm O.D. plastic hose was already in the shed.

The tube stops in the shoulder of the chamber and I have no back wash into the action.
I slowly pour half the bottle of filtered rain water through after three rounds and the barrel is well back to air temperature. I patch out the chamber with a large piece of felt and patch the barrel twice.

The cradle is an empty beer carton with a brick in the bottom to stablise it on the tray of my truck..
