Guys,

This is about cooling the barrel or the need to let the barrel cool down. First I'm going to be load testing my 7mag. The barrel gets extremely hot very fast. Three rounds and let it cool down. I've got 9 sets of three rounds which if I allow the barrel to cool 20 minutes between sets it's gonna take three hours. I'm not sure I'm going to have three hours today. Have any of you spread it out over two days in heat like this? Or do you just reduce the cool down time? Or would you use a cool damp cloth and cool the barrel with it?

Thanks,

Mel

Best option: use a cool damp cloth
Next best option: spread it out over 2 days
Worst option: reduce cool down time and risk shooting your best load on a hot barrel

I use a small battery powered air pump with a hose to blow air into the barrel to cool off quicker.

I did this yesterday. I took 3 rifles and rotated. I also use two fans, one is battery operated, really pointed it at me. The other goes up the chamber, works really good. If only testing 1 rifle, maybe take a .22 to pass the time.

I did see a shooter using a cold towel laid over his barrel. It was a composite stock, not wood. Take a small ice chest with ice a water, wring the towel out VERY good.
