Re: Load testing
I've read about several methods guys have used to cool their barrels quicker. Anything from placing cold wash cloths over the barrel, to making a chamber adapter to flush the bore with water, to using a product called a Winter Breeze Barrel cooling system that flushes the bore with CO2. Typically guys will find that cooling the barrels with water can lead to rust issues. I've seen many guys use alcohol instead to cool barrels. Their are alot of methods out there, but I've always employed good old air cooling when the barrel gets hot.
On a side note, has anyone ever done temp testing to see how hot a barrel can get during a group before it affects the group size? I have a laser thermometer that I've been meaning to take to the range with me to acquire some external and internal temps while firing groups.
