Keeping the Grendel cool at the range

[kcb38]

Bring a fan to the range and point it at the barrel. It will also blow the boiling air (mirage) away from above the barrel seen through the scope at high magnifications.

That's smart. A battery operated fan would keep the air moving and reduce fogging too (a big problem for me lately) plus it could help to keep gnats out of your face (another big problem lately). I don't see it doing a lot to cool the barrel but still, the only drawback I can see with it is that it's one more thing to carry. I'm off to Amazon to see what they have in the way of battery operated fans. I think I've seen some with rechargeable batteries too.
