Description
The Hornady Lock-N-Load Low Drag Sabot .50 Caliber SST-ML 300 Grain is a modern, high-performance muzzleloading bullet designed for hunters who demand accuracy and terminal performance. It combines a heat-resistant polymer tip, a Flex Tip bullet design to initiate expansion at lower velocities, and a low-drag sabot for a tight seal and consistent downrange energy. I’ve put a dozen of these through my own Thompson/Center Omega, and the on-target results speak for themselves.
Key Features
- Lock-N-Load Sabot: The patented, low-drag sabot provides a consistent gas seal for uniform pressure and velocity, shot after shot. It loads with firm, even pressure and is a true drop-in ready component.
- SST-ML Bullet: The 300-grain SST (Super Shock Tip) is built for muzzleloaders. Its Flex Tip initiates rapid, controlled expansion for devastating terminal performance, even at extended ranges.
- Heat-Resistant Tip: The red polymer tip won’t melt or deform from powder charge heat, ensuring reliable ballistic performance from shot to shot.
- Streamlined Design: The boat-tail base and sleek profile are engineered for a high ballistic coefficient, meaning it bucks the wind better and retains velocity and energy downrange.

Look, the whole point of a modern muzzleloader bullet is to bridge the gap between traditional round balls and centerfire rifle performance. This 300-grain SST-ML does exactly that. The sabot design is key—it’s not just a plastic wrapper. It’s engineered to engage the rifling consistently, which is why you’ll see tight groups with compatible in-line muzzleloaders like the CVA Wolf or Traditions Vortek. At $22.83 for a pack of 20, you’re investing in precision components, not just bulk projectiles.
Who This Bullet Is For
This is for the muzzleloader hunter who takes the extra season seriously. It’s for the shooter who hand-measures powder charges, cleans their barrel religiously, and wants a bullet that performs predictably on deer, elk, or bear. If you’re using a .50 caliber in-line muzzleloader and you’re chasing sub-MOA accuracy at 150+ yards, this sabot and bullet combo should be on your bench. It’s available at firearms-missouri.com for Missouri residents and nationwide.
Pros & Cons
Pros: Exceptional accuracy potential due to consistent sabot seal and high-BC design. The Flex Tip technology delivers reliable, dramatic expansion for quick, ethical kills. The heat-resistant tip is a small but critical detail for repeatable point of impact. Loads smoothly without excessive force.
Cons: Premium performance comes at a premium price compared to basic conicals or cheaper sabots. The rapid expansion is fantastic for deer, but for the largest game like moose, some hunters prefer a heavier, more deeply penetrating bonded bullet. Requires a compatible .50 caliber in-line muzzleloader.
Frequently Asked Questions
Q: What powder charge is recommended for this 300-grain SST-ML?
A: Always consult your firearm’s manual first. That said, these bullets are commonly and effectively used with 100 to 150 grains (by volume) of loose black powder or approved substitutes like Hodgdon Triple Seven or Pyrodex. Start at the lower end to find your rifle’s sweet spot.
Q: Is this compatible with my muzzleloader that uses 209 primers?
A: Yes, absolutely. The Hornady Lock-N-Load sabot itself is ignition-system agnostic. It works with #11 caps, musket caps, and 209 shotgun primers. Compatibility is about your rifle’s barrel and breech plug, not the primer type.
Q: How does the “Low Drag” sabot differ from a standard one?
A: The low-drag design has a more streamlined profile that reduces air resistance as the sabot and bullet travel down the barrel. This translates to slightly higher muzzle velocities with the same powder charge and, more importantly, less disruption to the bullet as the sabot petals peel away in flight, aiding accuracy.
Here’s the thing—muzzleloading has evolved. If you’re still stuffing patched round balls or generic sabots down your barrel, you’re leaving performance on the table. The Hornady Lock-N-Load Low Drag Sabot .50 Caliber SST-ML 300 Grain represents the current standard for hunters who treat their smokepole like a serious hunting tool. It’s a system engineered to work together, from the breach to the target. See if it’s the right fit for your next hunt.
