Nosler Custom Competition — .338 Cal, 250 gr HPBT (Hollow Point Boat Tail), 100/Box

Part No.: 57520 | UPC: 054041575201

Push big-bore precision farther. Nosler Custom Competition .338 caliber, 250-grain HPBT bullets are built for match shooters and long-range hunters who demand tight vertical spreads, minimal runout, and exceptional consistency shot to shot. From F-Class to ELR steel, this heavy-for-caliber, aerodynamic hollow point boat tail is engineered to hold velocity, resist wind, and print small groups—when your drop chart and trigger press are dialed in.

Why Reloaders Choose Nosler Custom Competition HPBT

• Match-grade manufacturing: Built to ultra-tight tolerances for weight, jacket concentricity, and ogive uniformity, supporting low ES/SD potential when your powder charge is on point.

• Aerodynamic profile: A refined ogive and boat-tail base reduce drag for flatter trajectories and improved wind performance at distance.

• Consistent meplats: Uniform hollow-point tips help stabilize BC and tighten groups across lots.

• Smooth feeding: Profile is optimized for reliable feeding in common .338 Lapua Mag, .338 Win. Mag, and other .338-caliber rifles (always confirm magazine and throat dimensions).

• Bulk value: 100-count box gives serious handloaders enough bullets to develop a node and then load out for matches or a season’s worth of practice.

Ballistics Note: Exact ballistic coefficients may vary by rifle, lot, and velocity. Always reference the latest Nosler load data and validate with your chronograph and downrange DOPE.

Performance You’ll Notice Downrange

• Tight groups at distance: Concentric jackets and uniform weight distribution support minimal yaw and more predictable flight.

• Reduced wind drift: A heavy 250-grain profile with a low-drag boat tail maintains momentum for better performance in rough air.

• Reliable seating & runout control: Consistent ogives and jackets make it easier to achieve uniform CBTO (cartridge base-to-ogive) when paired with a quality comparator and micrometer seating die.

Ideal Pairings & Applications

• Cartridges: .338 Lapua Magnum, .338 Winchester Magnum, .338-06, .338 RUM, and other .338-capable platforms (confirm twist rate).

• Twist Rate Guidance: Many rifles stabilize 250-grain bullets well with 1:10" to ~1:9.35" twists common in .338 magnums; verify with a stability calculator for your exact velocity and conditions.

• Use Cases: ELR/steel matches, load development and dope building, western big-game practice (check local regulations for hunting with match HPBT bullets).

Loading Tips (Best Practices)

1. Start low, work up: Always begin with published starting charges from a reputable manual and watch for pressure signs while incrementing.

2. Measure at the ogive: Seat to a consistent CBTO rather than overall length when chasing nodes and minimizing jump variance.

3. Neck tension & concentricity: Use uniform neck tension and check TIR/runout to tighten ES/SD and groups.

4. Chrono & confirm: Record true muzzle velocity, then confirm trajectory at 300, 600, and beyond to lock your solver.

5. Witness-mark hardware: After zeroing, paint-pen scope screws and base/ring fasteners; log torque values for repeatability.

Who It’s For

• ELR & precision competitors building reliable, repeatable match ammo.

• Long-range hunters and marksmen seeking heavy, high-BC bullet performance for extended practice and confident dope.

• Serious handloaders who value batch-to-batch uniformity and the ability to fine-tune seating depth and charge weight.

Safety & Compliance

• Projectiles only: These are bullets, not loaded ammunition.

• Follow load data: Use current Nosler or other reputable manuals; components, chambers, and environmental factors vary.

• Check local laws: Ensure bullet type and use meet your hunting and range regulations.
