• Requires a 1:8 twist or faster. Most 30 Cals are 1:10. Check what is stamped on your barrel
• This is a "bore rider" design and there is only a short band of full .3080 diameter. 
  • Seat the bullet to the edge of the band. You cannot adjust OAL.
  • The bullet will protrude the shell case mouth by ~1.38"! This makes the round extremely long. Here are a few ways to feed the long cartridge in your rifle:
    • Single feed. A 2 round holder attached to your rifle may be of value.
    • Use an extended mag box
    • Load in a short action cartridge, and use a long action rifle

This is a bore rider bullet design. Only a short section of full .3080" diameter remains seated in the case neck. Forward of this, the bullet transitions to bore diameter, which aligns it precisely with the rifle bore—even before firing. This alignment reduces yaw and improves concentricity for enhanced accuracy.

Because the nose begins at bore diameter, it doesn’t engrave into the rifling. This allows for a highly secant ogive profile, which optimizes aerodynamics and minimizes drag.

With only a short section at full diameter, TSX grooves are unnecessary, further improving flight efficiency. The solid copper construction and streamlined profile combine to deliver exceptional ballistic performance.

Every design choice in this bullet—starting from its bore rider construction to the secant ogive nose and the omission of TSX grooves—works in concert to maximize aerodynamic efficiency. By minimizing surface disruption, improving bore alignment, and streamlining the nose profile, Barnes has engineered its highest BC LRX bullet to date. The result is a long-range projectile that maintains velocity and resists drag better than any other in the lineup.
