Video: Does Warm Ammo Shoot Faster Than Cold Ammo?
OutdoorHub Reporters 09.08.15
Do warm rounds have a higher velocity than cold ones? Some people claim that military snipers will warm up ammunition in the sun so the heat can create higher pressures inside the round, therefore leading to a higher velocity when fired.
Enter The Wound Channel, who decided “test” the rumor by leaving several rounds out in the sun until they’re burning hot. In contrast, another group of rounds were cooled down with air conditioning until they were cold to the touch. So do “hot” rounds really go faster? Watch the video below to find out.
We’re not totally sold on the results (it was quite a small sample size), but we think it could be a good start toward something more conclusive.
