Hornady SST Bullets 30 Caliber (308 Diameter) 150 Grain InterLock Polymer Tip Spitzer Boat Tail Box of 100

Product Description

Hornady SST Bullets 30 Caliber (308 Diameter) 150 Grain InterLock Polymer Tip Spitzer Boat Tail Box of 100 are component bullets designed for reloading rifle cartridges in .30 caliber.

The polymer tip and boat tail profile work together to improve ballistic coefficient and downrange velocity. These bullets suit hunters and precision shooters who handload their own ammunition for whitetail deer, mule deer, and similar medium game.

The InterLock ring mechanically locks the jacket and core during expansion. That design helps the bullet retain weight and penetrate consistently after impact.

Key Facts

• Caliber: .30 Cal (308 Diameter)
• Bullet Type: Polymer Tip
• Grain Weight: 150 Grain
• Quantity: 100 bullets per box
• Profile: Spitzer Boat Tail

What the Polymer Tip Does

The polymer tip on an SST bullet initiates expansion upon impact and improves the bullet’s ballistic coefficient compared to an exposed lead tip. A higher ballistic coefficient means the bullet retains velocity better over distance and drifts less in crosswinds.

The tip also creates a more aerodynamic nose profile than traditional soft-point or hollow-point designs. For hunters shooting past 200 yards, that translates to flatter trajectory and more predictable drop.

Choosing the Right Grain Weight for 30 Caliber

A 150 grain .30 caliber bullet offers a middle ground between the lighter 125-130 grain options and heavier 165-180 grain projectiles. The 150 grain weight typically delivers flatter trajectory than heavier bullets while providing more retained energy than lighter ones.

This grain weight pairs well with popular cartridges like .308 Winchester, .30-06 Springfield, and .300 Winchester Magnum. It works particularly well when hunting medium game at ranges from 100 to 400 yards. Call 817-393-4000 if you need load data recommendations for a specific cartridge and powder combination.

InterLock Ring and Controlled Expansion

The InterLock design uses a raised ring inside the jacket that’s embedded in the bullet’s core. During expansion, this ring keeps the jacket and core from separating.

Controlled expansion and weight retention help ensure the bullet penetrates adequately after initial impact. For hunters, that often means better wound channels and shorter tracking distances compared to bullets that fragment or shed their jackets early.

Frequently Asked Questions

Q: What rifles and cartridges use 308 diameter 150 grain bullets?

A: Any rifle chambered in a .30 caliber cartridge that uses .308 diameter bullets can be loaded with these 150 grain SST projectiles. Common chamberings include .308 Winchester, .30-06 Springfield, .300 Winchester Magnum, .300 WSM, and 7.62x51mm NATO. Always consult current load data for your specific cartridge and powder before loading.

Q: How does the SST compare to other Hornady 30 caliber bullets?

A: The SST uses a polymer tip and InterLock ring, which differentiates it from Hornady’s traditional soft-point InterLock bullets and their match-grade offerings. The polymer tip improves ballistic coefficient compared to exposed-lead designs, while the InterLock ring provides controlled expansion. For specific differences in ballistic coefficient or recommended uses, call 817-393-4000.

Q: Can I use SST bullets for target shooting and practice?

A: Yes, SST bullets can be used for target shooting, though they are designed and priced for hunting applications. Many reloaders reserve polymer-tip hunting bullets for field use and choose less expensive full metal jacket or soft-point bullets for high-volume practice and load development.

Q: What is the difference between boat tail and flat base bullets?

A: A boat tail bullet has a tapered base that reduces aerodynamic drag and typically improves ballistic coefficient. A flat base bullet has a perpendicular cut at the base. Boat tail designs like the SST generally perform better at longer ranges due to reduced drag, while flat base bullets are often easier to load consistently for short-range precision work.

Q: Do I need any special reloading equipment for polymer tip bullets?

A: No, polymer tip bullets like the Hornady SST are loaded using the same presses, dies, and techniques as any other spitzer bullet. Take care during seating to avoid crushing or deforming the polymer tip by using proper seating stem geometry and adjusting ram pressure appropriately.

Q: How do I order or pick up component bullets at Western Sport?

A: Component bullets do not require an FFL transfer since they are not ammunition or firearms. You can order by phone at 817-393-4000 or visit the shop in Roanoke, TX. The team can also help you find compatible brass, powder, and primers for your reloading project.
