Ever wonder what would happen if your gun was frozen solid and you shot it?
If you didn’t you’re going to find out anyway.
…because it’s totally badass!!
The gun is a Remington R1 1911 and was frozen at -65°F 2 hours prior to being fired.
Ammunition used was the SIG Sauer 45 Auto V-Crown 200gr JHP load (E45AP1).
It was shot at the same temperature the gun was frozen at -65°F.
Now that you know what happens, here is why the test was conducted:
In the interest of helping those who live in Arctic and Subarctic climates choose climate-appropriate lubricant for their self-defense and hunting firearms, we temperature conditioned a Remington R1 1911 down to -65°F while lubricated with one of four popular firearm lubricants. The Remington R1 (save being a ‘series 80’ configuration 1911) was chosen because of its dimensional similarities to the widely-available 1911 handgun. Low temperatures tend to cause oil to thicken and lose some of its lubricating properties. The temperature point of -65°F was chosen as it represents the reasonable worst-case scenario for the coldest locations on earth and is the low temperature specified in NATO STANAG 4090 (Edition 2).
Ammunition performance also changes drastically in the face of extreme cold. Depending on the primer and the nitroglycerine content of the propellant used, chamber pressures can either drop or spike dangerously above SAAMI pressure limits. We went with the SIG Sauer 45 Auto V-Crown 200gr JHP load (E45AP1) after pressure testing many different manufacturers ammunition at -65°F on SAAMI conformal pressure equipment and finding that the SIG load offered the lowest pressure drop among the cartridges tested. In order to establish our baseline, the test firearm was cleaned in an ultrasonic cleaner for 30 minutes and then heavily lubricated with the lubricant to be tested. The firearm was then shot with a fully-loaded magazine (7 cartridges) until the last shot was fired. This sequence of events was captured on slow motion video using a Phantom 711 high speed video camera.
In evaluating a bivariate system (in this case the extreme cold effect on both the ammunition and the firearm/lubricant) it is essential to first evaluate the effect of each factor independently to determine their influence on the system results. Accordingly, after the test 1911 was shot in the clean/70°F temperature condition with Remington Rem Oil, it was ultrasonically cleaned, lubricated with Remington Rem Oil and shot at room temperature with SIG Sauer 45 Auto V-Crown 200gr JHP that had been temperature conditioned to -65°F.
Performance in the context of this test is defined by the time required for the firearm to fully move the slide rearward and the time required for the firearm to fully move the slide forward. This time was measured by slow motion videography and the HSV cameras internal clock. The firearm and ammunition were conditioned for a minimum of 1 hour at -65°F prior to shooting. Both ammunition and gun were returned to a Thermotron temperature cell in the range after each shot and the temperature inside the unit allowed to return to -65°F before gun and ammunition were returned to firing position to continue testing.
