Gainesville, GA –-(Ammoland.com)- With winter nearly upon us (and, in some cases, already on us hard), longer-range hunters must be ready to make precise shots despite cold weather. Ballistic can be a huge help here.
“Colder temperatures definitely have an effect on bullet speed,” said Curt Vaughn, veteran long-distance shooting competitor and Head of Product for Ballistic. “Even reloader’s using Extreme-rated powders can see a significant change in velocity.”
For example, when Vaughn’s .243 Ackley Improved handload is fired at 80 degrees, this load generates a muzzle velocity of 3,286 feet-per-second (fps), and the bullet stays supersonic out to 1,450 yards. But at 20-degrees Fahrenheit? This very same load now has a muzzle velocity of 3,175 fps and drops to subsonic speed at 1,350 yards.
For the long-range hunter, such differences in muzzle velocity are huge and can be the difference …Read the Rest
