Barrel cooler

[Wind River]

Looks like a good way to cool one off. I’ve seen the little units made for barrel cooling and am not impressed.
We do not have a managed rifle range in my area so I shoot on BLM at a range we set up using fence posts pounded in with oak pallets for target holders. My truck is always only a few feet from my home made shooting bench. I’ve found that the best way to cool a barrel is to get it out of the sun and leave the rifle on the front seat of the truck with the air conditioner blasting. Cools ‘em pretty fast.

On the other hand, some say barrel cooling does more harm than good when it comes to barrel life...including some Swiss researchers.

Good evening Haven’t seen too much written about them lately… Curious if you are using one, and what brand you suggest? Thanks for the input

Counterintuitive, but after reading it, and knowing what I know about the thermal movement of steels -- particularly stainless -- it kinda makes sense.

(A related issue, and one I haven't seen discussed, is that many stainless steels have poor thermal conductivity, which makes them notoriously difficult to weld without excessive warpage and distortion. Theoretically, this should make aggressive cooling methods -- whether it's wet rags, cold packs, alcohol wipes, or bore blowers -- cause differential cooling and movement of the barrels and POI. But I don't hear anecdotal evidence of this, so go figure.)

What is the brand of stock you have on the pistol?

it is an xlr industries element 4.0 magnesium. It's my first time shooting a centerfire "pistol" and so far it's going quite well. Pretty comfortable to shoot off of and doesn't seem to be counterintuitive towards precision. So far fireforming with a very mild load and hornady 53 vmax has yield consistent 1/4 to 1/2 moa groups at 200 yards.

My kids gave me a little Jackery battery pack for Christmas. The first time I carried it and a small fan to my little range, which is in a 5 year old timbered out woods ..no breeze, I knew I would never go again in the summer without it!

It has usb-outs, 12v out, and a couple of 120v outs. I got a couple of usb fans and blow one over the barrel/in the chamber, and on me. They draw 5 watts , can go for hours. Charge the Garmin zero, phone, whatever.

They gave it to me mainly for home back-up for devices, light, etc, but it’s a small 7# cube, easy portability. Recharges from 120v, 12v car, usb-in, or a solar panel. Lots of other brands, I’m sold! I think it’s worth having one around the house, and perfect for camping/hunting too.

It's easy and cheap to make one. This one cost me $25 and has 45 minutes of power between charges.
