Quick Answer
The length of the barrel in a .280 AI rifle can affect its performance, with longer barrels generally providing better accuracy and increased velocity, but may also increase weight and overall length.
Barrel Length and Accuracy
A longer barrel can help to reduce the effects of barrel harmonics and provide a more consistent shot-to-shot accuracy. For the .280 AI, barrels between 24 and 26 inches are common and can provide excellent results. However, some shooters have reported improved accuracy with longer barrels, up to 28 inches. This is because longer barrels allow for more time for the bullet to stabilize in flight, resulting in a flatter trajectory and tighter groupings.
Barrel Length and Velocity
In addition to improved accuracy, longer barrels can also increase the muzzle velocity of the .280 AI. This is because a longer barrel provides more time for the powder to burn and accelerate the bullet. For example, a 24-inch barrel may produce a muzzle velocity of around 2,800 feet per second, while a 26-inch barrel may produce a velocity of around 2,900 feet per second. This increase in velocity can result in a flatter trajectory and a more effective hunting cartridge.
Practical Considerations
When deciding on the length of the barrel for a .280 AI, shooters should consider the trade-offs between accuracy, velocity, and practicality. A longer barrel may provide improved accuracy and velocity, but may also increase the weight and overall length of the rifle. Shooters should also consider the type of shooting they will be doing most often, as well as any local regulations or restrictions on barrel length. A good rule of thumb is to start with a shorter barrel and increase the length as needed based on individual results and preferences.
