Quick Answer
Temperature affects 28 Nosler performance in that it impacts bullet expansion, velocity, and kinetic energy, with optimal performance typically occurring at temperatures between 40°F and 70°F. At colder temperatures, expansion is reduced and velocity is decreased. At warmer temperatures, expansion is increased but velocity is also reduced.
Temperature and Expansion
Expansion is a critical factor in long-range hunting, particularly with the 28 Nosler. The bullet is designed to expand at a specific temperature range, typically between 40°F and 70°F. Within this range, the bullet expands to its intended diameter, providing maximum kinetic energy transfer to the target. At temperatures above 70°F, the bullet may expand too aggressively, leading to inconsistent performance. Conversely, at temperatures below 40°F, expansion may be reduced, resulting in less kinetic energy transfer.
Temperature and Velocity
Temperature also affects the velocity of the 28 Nosler. In general, velocity decreases with decreasing temperature. For example, a 28 Nosler 150-grain bullet fired from a 26-inch barrel at 70°F may travel at approximately 3,100 feet per second (fps). At 40°F, the same bullet may travel at approximately 2,900 fps. This is a significant drop in velocity, which can impact the bullet’s long-range performance.
Managing Temperature Effects
To manage temperature effects on 28 Nosler performance, hunters and shooters can employ various techniques. For example, using a muzzle brake or suppressor can help maintain bullet expansion and velocity in cold temperatures by reducing the barrel temperature. Additionally, using a high-quality, temperature-stable ammunition can help ensure consistent performance across a range of temperatures. By understanding the effects of temperature on 28 Nosler performance and employing these techniques, hunters and shooters can optimize their long-range success.
