Ballistics Table

Manufacturer-published reference. Zero: 200 yd. Sight height: 1.5 in. Test barrel: 24 in. Only verified published rows are shown. No interpolated distances or independently calculated trajectories are included.

Key takeaway: These are reference ballistics, not a guaranteed hunting distance. Retained energy alone does not establish expansion, penetration or suitability for a particular shot. Actual velocity and point of impact depend on the rifle, ammunition lot and conditions. Confirm the rifle’s zero and measured performance before relying on a trajectory.

The Hornady SST Bullet and Superformance Propellant System

The Super Shock Tip (SST) bullet is a polymer-tipped, lead-core projectile designed to initiate rapid and consistent expansion across a wide range of impact velocities. The red polymer tip drives rearward into the lead core on impact, initiating expansion while the InterLock ring – an internal jacket feature that mechanically locks the jacket to the core – resists jacket-core separation at high velocity. This makes the SST a versatile choice across a broad range of distances where impact velocity can vary considerably.

What separates this load from standard 338 Win Mag offerings is the Superformance propellant blend. Rather than simply increasing powder charge, Hornady engineered a propellant mixture that burns more efficiently across the full length of the barrel, generating higher muzzle velocity without a corresponding increase in peak pressure or felt recoil signature beyond what the caliber already produces. Hornady markets Superformance for increased velocity. The exact factory rating is shown above; this claim does not establish the gain in every rifle.

Best Uses

Good fit:

• Big game hunting where this exact expanding-bullet load meets the needs of the hunt.
• Comparing factory ammunition in the same rifle while recording group size, velocity, lot number and conditions.
• Hunters comparing projectile construction and practical accuracy, rather than muzzle velocity alone.

Limitations:

• No fixed ethical hunting range follows from the energy column alone.
• Factory test-barrel results may differ from an individual rifle. A fixed velocity loss per inch is not assumed.
• This page does not establish lead-free certification for the exact product.

Reliability Notes

No structured AmmoReports firing-test submissions are recorded in this article. Manufacturer reference data must be kept separate from independent chronograph, accuracy and terminal-performance tests. No unverified forum consensus, accuracy guarantee, case-life estimate or claim of recall-free status is presented as a measured result.

Competitors

The original comparison list is retained for identification and follow-up. Listed names, weights and projectile labels are not independently confirmed product records. Unverified BC, velocity, price and performance claims have been removed. A handload reference, if listed, is not a factory-ammunition equivalent.

Price Reality

Compare the exact cartridge, projectile, weight, SKU and package quantity before comparing offers. Box and case listings can use different UPCs. Cost per round should be calculated from a current store offer, including shipping and applicable taxes. No undated retail-price benchmark or current-stock claim is asserted here.
