Quick Answer
For Swift Scirocco bullets on elk, an optimal speed range is between 2,200 to 2,400 feet per second (fps), which will provide the best expansion and penetration.
Optimal Speed Range
The optimal speed for a bullet to expand properly on an elk is crucial for a quick and humane kill. The Swift Scirocco bullet, being a bonded design, requires a certain speed threshold to initiate expansion. At speeds below 2,200 fps, the bullet may not expand sufficiently, leading to deeper penetration and potentially a longer recovery time. Conversely, speeds above 2,400 fps may cause over-expansion, resulting in a loss of kinetic energy and less effective penetration.
Bullet Performance Considerations
When choosing the optimal speed range for the Swift Scirocco on elk, consider the rifle’s caliber and barrel length. For a 7mm Remington Magnum (RM) with a 24-inch barrel, a muzzle velocity of around 2,250 fps will be achievable. This speed range will ensure that the bullet expands properly, with a 1-inch expansion at the target, and penetrates to a depth of about 12-15 inches.
Field Performance and Recovery
In the field, it’s essential to consider the speed of the bullet and its impact on the elk’s vital organs. At the optimal speed range, the Swift Scirocco bullet will penetrate the heart and lungs, causing instant incapacitation. This allows for a quicker and more humane recovery, reducing the risk of a wounded elk escaping and potentially leading to a more challenging recovery process. By selecting the right speed for the Swift Scirocco, hunters can ensure a quick and clean kill, making the most of their hunting experience.
