The 17 I'm using now was bought up in upstate NY. I had it for 1 fall, 1 winter, and then 1 spring. Then I moved down to FL. I recently had a barrel overheat on me (it's all good though). The temp the day this happened it was 91 degrees. Can this actually aid in the barrel overheating? Are there any other things that I should keep in mind in high temp shooting? I'm interested because I have always lived in upstate ny until now, and have never had any of my barrels overheat on me until now. Any advice would be great.

Re: High Temp Weather
I did see a magazine for an AR-15 that has a squirrel cage fan inside for cooling off your bore ($60 ish), i.e. if you were varminting and had one rifle overheating, you could cool it off while switching to a 2nd gun.
Thing to do is periodically feel or get a temperature reading off your barrel somewhere in the middle, maybe 3" or so ahead of the chamber and take record of the temperature readings in relation to your groups opening up. If you can find a correlation between a drop in accuracy and barrel temperature, you will have established your limits for that gun. If your gun starts getting too hot, let it cool off. Good time to clean the bore, while its hot fouling is removed easier..and the solvent soaked patches would probably aid in cooling the barrel off.

Barrel heating is more a function of a series of rounds fired in a short period of time than of the air temperature. The air temperature does matter somewhat, because most powders burn faster at higher temperature, but I live in south Texas, and we don't consider 91 degrees F to be <span style="font-style: italic">hot.</span>

Re: High Temp Weather
Haha Lindy. My wife has lived down here before and she tells me if I think this is hot to wait for August.
A temp reasing would be cool. Do they make any gauges or something like that for barrels? Maybe I can just slap on one of those sticky fish tank ones.

Re: High Temp Weather
That's what I was wondering about too. Kind of how the fish tank ones work. But those are like $1 and these are $9 so maybe they figured a way around that. I'll just stick to slow firing and cooling breaks for now.

My friend Victor sells/sold them for sports racers to check tire and brake rotor temps. They are down to about a c-note now. He's in his 70's and the business is in transition to the younger generation. I've sold several myself for him when I work at the track (Watkins Glen) helping him out. Plans are for us to get together at The Glenn Memorial Day W/E for the Porsche Club events. I'm pretty sure he's still moving them, I think the web site may just not be fully up to date.
The problem with barrel heating and hot weather involves heat transfer. The warmer the surrounding air is, the less the temperature differential, and the surrounding air can only absorb a lesser amount of heat energy, so more air must move past the heated object (barrel) in order to transfer the same volume of heat. Usually it doesn't, so barrels get hotter and take longer to cool.
