Barrel fan

[Nambaster]

Has anyone used a barrel fan to circulate air in your rifles between shooting? I am just curious if they speed up your range time in waiting for your barrel to cool.

Worth the $60?

Seems interesting. I’ve used my m18 fan to try and cool down barrels a bit because I already had it. I could see the advantages if your into regular load development or developing a load or just want to do a lot of cold bore practice.

I just pee down it between strings

Its not terribly expensive. I have spent a lot of time waiting on barrels to cool. If it works, It would be nice to have.

I normally have 2 or three rifles out when I am shooting so I just shoot a few rounds in one and then switch to another while the other is cooling.

I use a battery powered mattress inflator. Cheap and works great.

This. They even make them rechargeable like everything else nowadays! Throw a piece of tubing on it and feed it right into the action.

I use a chamber chiller after every shot. Solder joint inside the unit was less than adequate so I bypassed the switch and it works fine now.

I’ll be doing load development but I have 3 rifles to alternate so I wonder if I will really need it.

I like the MagnetoSpeed RifleKuhl. I'll use it between 5-shot strings for 3-5 minutes and it seems to work pretty well.

On my last outing I was shooting a 300 WM on a sunny 90deg day with a hunting weight barrel. It tends to overheat easily.

This last time I took four ziploc gallon bags. Each had a wet dish towel. Then I packed them with ice packs. Between 3 shot groups, I laid them over the barrel and action. It worked amazing and I shot my best groups out to 750 ever with that rifle.

With a foot of cheap high temp fuel line from Oreilly's jammed into the chamber.

I find that if you really want to maximize heat transfer you can block the muzzle end airflow a bit/randomly. This increases turbulence inside and thus increases heat transfer for a given mass flow rate. Laminar flow isn't really great at heat transfer, but better than nothing.

I've been considering the wet towel trick in addition, but at the end of the day I'm really only concerned about the chamber temp where a wet towel won't help as much or cool evenly. Suppressor covers take care of mirage for the most part.

That’s what I use, bit overpriced for a little fan and tube but does help speed up the cooling. The battery thing is trash but any power bank works.

I have used something like this:
amazon rechargeable fan

They don't make the one I have but you can find something similar and all I did was put a small piece of flexible hose on the end and stick it in the chamber and away you go.
