When it comes to muzzleloader hunting, shot placement and bullet performance are non-negotiable. The 300-grain weight offers an excellent balance of flat trajectory and knockdown power, making it a versatile choice for whitetail, elk, or bear. At a price of $28.47, this pack delivers premium Barnes terminal performance at a practical cost per round, a critical consideration for any serious hunter. The pre-assembled sabots mean these are drop-in ready for your rifle—no fumbling with loose components in the field or at the range.
Who This Is For
This product is built for the modern muzzleloader hunter who has moved past round balls and conicals. It’s for the shooter using a CVA Accura or a Thompson/Center Omega who needs a bullet that performs reliably at both close-range brush shots and longer shots across a Missouri crop field. It’s for the hunter who values ethical harvests and wants a projectile that will expand violently yet retain nearly 100% of its weight to drive deep into the vitals. If your state requires lead-free projectiles, this copper bullet is your direct answer.
Pros & Cons
Pros: Exceptional weight retention and penetration. Consistent, predictable expansion. The pre-engraved design eases loading, especially in colder weather. The included sabot system is compatible with most modern .50 caliber in-line rifles. The 24-count package offers solid value for a premium hunting bullet.
Cons: As a premium copper bullet, the cost is higher than traditional lead conicals. The specific sabot fit may require testing for optimal accuracy in your individual rifle—though most shooters find it fits out of the box. The 300-grain weight may have a slightly more arched trajectory than lighter bullets, requiring precise range estimation.
Frequently Asked Questions
Q: What powder charge is recommended for this 300-grain bullet?
A: Always consult your rifle’s manual first. For most modern in-lines, a charge between 90 and 120 grains of volume-equivalent black powder or a substitute like Blackhorn 209 is an effective starting point for balancing power and recoil.
Q: Are these compatible with my muzzleloader?
A: They are designed for .50 caliber in-line muzzleloaders with a 1:28 or faster twist rate, which includes popular models from CVA, Thompson/Center, and Knight Rifles. They are available at firearms-missouri.com for Missouri residents and nationwide.
Q: How does the expansion compare to a traditional lead bullet?
A: The solid copper construction and Expander MZ tip cause the bullet to peel back into sharp petals, creating a permanent wound channel often larger than a lead bullet, which can fragment. Copper retains virtually all its mass for through-and-through penetration.
That said, your gear is only as good as your familiarity with it. These bullets offer a repeatable, high-performance platform. Stock up for the season, confirm your zero, and head afield with confidence. Add the Barnes 45162 Muzzleloader 50 Black Powder Expander MZ 300gr, 24Pk to your cart to secure your supply.
