This rig was set up with a water cooling system for dedicated rifles using a 50 gal portable water tank and pump system, driven electrically via a solor panel laid out on the ground. It kept the water-jackets and barrel a constant 46*F, no matter how fast the rifle was fired. Full custom rigs with Hall actions, Pac-Nor barrels under the water jackets in 223 and 6-284.
Please excuse the photo quality, as these were scanned from prints, and the originals were shot with a very old digital camera from the late 90's.
Cooling was done with a manifold running down both sides of the trailer, the pump always running and supplying fresh, cool water to the barrels. Both volume and pressure regulators can be seen; a real nice setup.
The condensation can be seen on the barrel aft of the break from the cool water.
The rig had four shooting positions with a rifle rack in front with the water tank concealed at the tongue of the trailer. Everything stows away nicely for the highway.
The large solar mat used to power the water pump. Works great, no hot barrels on this rig.
Yours truly having my way with the WY dogs with one of the 6-284's, reaching way out there. All ammo was custom loaded for the trip by Barnes, and it was good stuff! I could hit dogs past 500 yds no problem with the 6mm rig, as the wind cooperated that day and the dogs had excellent flying lessons.
When out in the field shooting grass rats, you just never know what interesting gear you might see, and I thought this rig truly qualified for "interesting", not to mention a boatload of fun.
