Quick Answer
A one-in-eight (1:8) or one-in-seven-twelve (1:7.2) twist rate is recommended for 7mm Remington Magnum accuracy, providing stability for long-range shooting and optimal expansion of heavier bullets.
Twist Rate and Bullet Stability
A stable twist rate is crucial for accuracy in long-range shooting, particularly when using heavy bullets that may destabilize and exhibit keyhole or fragmentation patterns. The 7mm Remington Magnum cartridge, with its moderate case capacity and a relatively long bullet, requires a twist rate that balances stability and expansion. A one-in-eight (1:8) or one-in-seven-twelve (1:7.2) twist rate strikes the ideal balance, allowing the bullet to expand consistently and accurately up to extreme ranges.
Choosing a Barrel Maker and Finish
When selecting a barrel maker, consider those who specialize in precision rifle manufacturing, such as Bartlein, Krieger, or Hart. These manufacturers often employ tight-tolerance tolerances and advanced machining techniques to minimize play and enhance accuracy. Additionally, consider a matte or satin finish, which can help to reduce glare and minimize the visibility of the barrel.
Bullet Choice and Weight for 7mm Remington Magnum
When hunting elk with a 7mm Remington Magnum, choose a heavy bullet with a high ballistic coefficient. The Berger 168-grain Elite Hunter VLD or the Sierra 175-grain Tipped MatchKing are excellent options, providing excellent expansion and deep penetration. Consider using a muzzle brake to minimize recoil and aid in quick follow-up shots.
