Quick Answer
The effectiveness of a 260 Remington in hunting deer can be influenced by factors such as ambient temperature, humidity, wind speed, and deer weight, as well as the type of bullet used and the hunter's skill level.
Ballistic Factors
When hunting with a 260 Remington, it’s essential to consider the effects of temperature and humidity on bullet expansion. A temperature increase of 20 degrees Fahrenheit can result in a 2-3% increase in velocity, while a 1% increase in humidity can cause a 0.5-1% loss in velocity. For example, a 120-grain bullet traveling at 3,000 feet per second in 40°F air could experience a 50-foot-per-second loss in velocity at 60°F due to temperature expansion.
Bullet Selection
Choosing the right bullet for a 260 Remington is crucial for effective deer hunting. For lighter deer weighing less than 150 pounds, a 100-grain bullet with a sectional density of 0.22 or higher and a muzzle velocity of 3,000 feet per second or higher is recommended. For heavier deer, a 120-grain bullet with a sectional density of 0.25 or higher and a muzzle velocity of 3,000 feet per second or higher is more suitable.
Wind Callibration
When hunting in windy conditions, it’s essential to compensate for wind deflection. For a 260 Remington, a 1-mph increase in wind speed can result in a 0.5-1.5 inches of bullet deflection at 100 yards. To compensate, hunters can use a wind callibration chart or consult with an experienced shooter to determine the necessary correction.
