If you're in that much of a hurry get yourself a O Ring Cleaning Rod Guide from Sinclair International, tap the end for the hose end of a Nitrous Oxide Bottle stainless steel line, and use that to cool down your barrel!!! Some can be found rather cheap for the older ones, 10 Lbs. Bottles are nice, not too heavy, comes out at a -276 degrees if I remember correctly? I used it often on my race car back in the day when I was a serious drag racer, although the filling of Nitrous Oxide is not cheap!
