[QUOTE="AZShooter, post: 1852496, member: 5219"] I think a hunter should try and duplicate hunting conditions when developing a load. . Owning multiple rifles helps. I will work up loads for a particular rifle in similar temperatures that will be encountered while hunting. Iprefer While shooting at the range, as you observed the barrel temperature quickly increases with multiple shots. I rarely shoot more than two shots with the big magnums and three with medium sized cases. I want the barrel as close to ambient temperature as possible. I know a well known local gunsmith who will shoot one shot allowing barrel to cool naturally to ambient before shooting another shot. This becomes an all morning affair. I prefer to accelerate the cooling time if I didn't bring multiple rifles or if time is a factor. There are many ways to cool off the barrel. If accelerated cooling is desired many run cold water across the outside of the barrel and some even run water through the bore! Naturally the bore must be swabbed out to remove all water. Other shooters use a damp towel wrapped around the barrel. Using forced air is far slower than using a liquid but less messy. Some use small air pumps that are used to inflate an air mattress. While I haven't seen it yet, a air compressor with higher flow would be faster. Fastest way to cool with air I know of and use myself, is to use a CO2 tank with a tapered hose to fit tight into end of chamber. Mild flow will cool a barrel to ambient temperature in 20 or 30 seconds. As barrel is cooling stop flow before outside gets to ambient as cooling will continue as the cooler inside radiates towards outside. I have used this system for well over a decade when time is a factor in developing a load. The 20 lb tank costs around $22 dollars to fill but will last several range sessions.
