Use Stick-On Temp Strips to Monitor Barrel Heat in Summer

Barrel Heat Temp Temperature gauge strip McMaster Carr

Summer is coming soon, and temperatures are starting to heat up. We are already seeing unseasonably hot conditions in many areas of the country. You never want your barrels to get too hot, which can happen more quickly in summertime. Accuracy suffers when barrels over-heat, and excessive heat is not good for barrel life. So how do you monitor your barrel’s temperature? You can check if the barrel is “warm to the touch” — but that method is not particularly precise. There is a better way — using temperature-sensitive strips. McMaster.com (an industrial supply house) offers stick-on temp strips with values from 86° F to 140° F. A pack of ten (10) of these horizontal strips (item 59535K13) costs $14.06. That’s a mere $1.40 per barrel for strips — cheap insurance for your precious barrels. For best barrel life, you should try to keep your barrels under 120 degrees F.

Forum member Nomad47 says: “I have temperature strips (bought at McMaster-Carr) on all my barrels. I try not to shoot when the barrel gets to 122 degrees or higher[.]” Here are photos of the McMaster-Carr temp strips on Nomad47’s customized Savage.

Creedmoor Sports now offers handy Temp Strips, with 3-packs for $12.95. These have colored temp range markers so you can quickly see if your barrel is getting too hot. Creedmoor Sports notes: “The temperature range of 30-160° spaced in 10° increments fit most … shooting situations. The 1″-wide 6″-long LCD strip will provide many years of service. In general, we recommend that if a barrel begins to reach 140°, it is too hot and continuing to shoot at these temperatures accelerates barrel wear These barrel temperature strips use a 3M® adhesive and will stick to blued, parkerized and stainless barrels.”

Bad things can happen if your barrel gets too hot. First, with some barrels, the point of impact (POI) will shift or “walk” as the barrel heats up excessively. Second, even if the POI doesn’t change, the groups can open up dramatically when the barrel gets too hot. Third, if the barrel is very hot, the chamber will transfer heat to your loaded cartridge, which can lead to pressure issues. Finally, there’s considerable evidence that hot barrels wear out faster. This is a very real concern, particularly for varmint shooters who may shoot hundreds of rounds in a day. For this reason, many varminters switch among various guns, never letting a particular barrel get too hot.

Neconos.com offers BAR-L Temp Strips that visually display heat readings from 86 to 140 degrees. Think of these strips as compact, unbreakable thermometers that monitor barrel heating.

Put a strip on the side of the barrel and the barrel’s temp will be indicated by a stripe that changes from black to green. There is also a “general purpose” strip that reads to 196 degrees (see bottom row). The Benchrest model strip (86°F to 140°F) is in the middle. These Bar-L temp strips cost $12.70 each, or $25.00 for a 3-pack.

NOTE: These strips can be permanently fixed to the barrel with the heavy-duty clear plastic tape strip provided with the BAR-L Temp strip.

Don’t Fry Your Barrels — Monitor Barrel Heat with Temp Strips

Barrel Heat Temp Temperature gauge strip McMaster Carr

August is almost here, so we’re near the peak heat of summer. We are already seeing extremely hot conditions in many areas of the country. You never want your barrels to get too hot, which can happen more quickly in summertime. Accuracy suffers when barrels over-heat, and excessive heat is not good for barrel life. So how do you monitor your barrel’s temperature? You can check if the barrel is “warm to the touch” — but that method is not particularly precise.

A pack of ten (10) of these horizontal strips (item 59535K13) costs $13.16. That’s a mere $1.32 per barrel for strips — cheap insurance for your precious barrels. For best barrel life, try to stay under 120 degrees F.

Monitor Barrel Heat with Handy, Infrared Thermometers

Monitor Barrel Heat with Pocket Infrared Gauges
It’s the middle of summer, and temperatures are HOT around the country. That makes it more important than ever to monitor your barrel temp when at the range. You NEVER want to run the barrel of a precision rifle too hot. Excessive barrel heat kills accuracy, increases copper fouling, and can cause rapid barrel throat wear. Over the years people have devised various means to cool their barrels — from electric fans to dunking in tubs of ice water.

But how do you know if your barrel is too hot? Consider a “non-contact” thermometer that reads your barrel’s “infrared signature”. The small pocket-sized, non-contact Infrared (IR) thermometers are ideal for shooters at the range or in the prairie dog fields. Such thermometers are handy and inexpensive. You can buy these mini IR pen thermometers for under $15.00 from Amazon, Walmart, and other vendors.

Pen-Sized Thermometers
Just 3.2″ long, and weighing an ounce, these handy IR pen thermometers are small enough to carry in your pocket, and will easily stow in any range bag/box. The Yidexin unit, sold by both Amazon and Walmart, can measure from -58 to 428 °F (-50 to 220 °C). You can also find considerably larger hand-held IR thermometers for industrial applications. These can measure up to 716 °F. But for quick measurement of barrel temps, we prefer the small pen IR thermometers that fit in a pocket. A little IR thermometer like this is a gadget that every serious shooter should have. Given the cost of replacing barrels these days (up to $700 for barrel, chambering and fitting), can you afford NOT to have a temp gauge for your match or varmint barrel?

TECH TIP — How to Get More Consistent Readings
When using IR Thermometers on shiny steel barrels, sometimes the polished surface throws off the beam, causing inconsistent readings. You can solve this problem by simply putting a piece of masking tape on the area where you take your reading. Some other folks use a grease pencil to create a non-reflective spot to read. Forum Member Jon B. says: “I used an Exergen infrared in the HVAC industry. Without the grease crayon they sold, you couldn’t get an accurate reading with shiny metals.”
