Description
For the American hunter or target shooter who relies on a muzzleloader for the fall season or a dedicated black powder range session, the Barnes 45172 Spit-Fire TMZ offers a consistent, high-performance option. Designed specifically for 50 caliber inline muzzleloaders, this 15-pack of 250-grain sabots provides a balance of accuracy and terminal performance suitable for taking game like whitetail deer or for punching tight groups on paper. When you need a projectile that loads smoothly and delivers reliable expansion, this Barnes load is a practical choice for your black powder rifle.
What This Product Is and Who It Is For
The Barnes 45172 is a factory-loaded muzzleloader projectile, specifically a 250-grain Spit-Fire TMZ sabot. This product is a 15-count package of pre-assembled sabots and bullets, designed for shooters who prefer the convenience and consistency of a factory-engineered load over hand-pressed components. It is intended for owners of modern inline muzzleloaders that use 50 caliber barrels and 209 primer ignition systems.
This product is suitable for several types of shooters. Hunters who pursue medium to large game in states with dedicated muzzleloader seasons will find this load effective. Target shooters who want a consistent projectile for zeroing and practice will appreciate the uniform construction. Collectors who maintain a working black powder firearm for seasonal use will also find this a straightforward option for keeping their rifle operational. It is not designed for home defense or concealed carry, as those roles are better served by modern handguns and centerfire rifles.

Feature Deep-Dive
The Barnes Spit-Fire TMZ is built around a lead-free bullet design, which is a significant feature for hunters in states with restrictions on lead ammunition. The bullet itself is a total metal jacket (TMZ) construction, meaning a copper jacket fully encases the core. This design promotes deep penetration and high weight retention upon impact, which is valuable when pursuing game at typical muzzleloader ranges. The 250-grain weight is a versatile option, offering enough mass for deer and similar-sized game without excessive recoil in most rifles.
The sabot component is equally important. Barnes uses a pre-formed polymer sabot that is engineered to engage the rifling of a 50 caliber barrel consistently. This sabot is designed to be loaded with moderate pressure, reducing the need for a mallet or excessive force during the loading process. The sabot also helps center the bullet in the bore, which contributes to accuracy. For the shooter, this means less time spent fighting with stubborn loads and more time focusing on sight alignment and trigger control.
Another practical feature is the TMZ bullet’s performance across a range of velocities. While muzzleloader velocities can vary based on powder charge and barrel length, this bullet is engineered to expand reliably at typical muzzleloader speeds (around 1800-2200 feet per second). The copper construction resists deformation during loading and handling, which is a common issue with softer lead bullets. This durability also means the bullet is less likely to shatter on bone, instead driving through to deliver energy to the vitals.
The 15-round count is a deliberate choice. It provides enough ammunition for a thorough range session to confirm your zero, practice a few shots, and still have a full load for a hunting trip. It is not a bulk pack for high-volume practice, but it is ample for the shooter who wants to load a rifle, test a few groups, and then have confidence in the remaining rounds for the field. The packaging is compact, fitting easily into a range bag or a pocket of a hunting vest.
Consistency is a key advantage of factory sabots. Each Barnes Spit-Fire TMZ unit is assembled to the same specifications, which reduces variables that can affect point of impact. For the shooter who wants to eliminate the guesswork of matching sabots to bullets, this is a straightforward solution. The pre-assembled nature also saves time at the loading bench, as you do not need to seat a bullet into a separate sabot.
Finally, the Barnes brand carries a reputation for quality control in the ammunition industry. This specific load has been tested for compatibility with a wide range of inline muzzleloaders, including popular models from Thompson Center, CVA, Knight, and Traditions. While individual rifle barrels can vary, the Spit-Fire TMZ is a known quantity that many shooters have used successfully for years. This track record provides a level of confidence for the buyer who wants a load that performs as advertised.
Ideal Use Cases
Hunting: This is the primary use case for the Barnes 45172. The 250-grain lead-free bullet is well-suited for whitetail deer, hogs, and black bear at typical muzzleloader engagement distances (under 150 yards). The deep penetration and reliable expansion make it a solid choice for ethical shots on medium-sized game. Hunters in states with mandatory non-lead ammunition requirements will find this load compliant.
Target Shooting: The consistent sabot and bullet design make this load suitable for target practice and zeroing your muzzleloader. The 250-grain weight provides a predictable trajectory, and the 15-round count allows for a meaningful group-testing session. It is not a budget option for high-volume plinking, but it is a reliable choice for confirming your rifle’s accuracy.
Competition: Some muzzleloader competitions allow factory sabots, and this load can be used for side matches or informal competition. However, it is not specifically marketed as a match-grade product. It is more suited to practical hunting scenarios than benchrest competition.
Compatibility Notes
This product is designed for 50 caliber inline muzzleloaders with a 1:28 or slower twist rate. It is not intended for traditional sidelock muzzleloaders or round ball rifles. The sabots require a 209 primer ignition system for consistent ignition. You will need to supply your own black powder, black powder substitute (such as Pyrodex or Triple Seven), and 209 primers. The recommended powder charge range is typically 100 to 120 grains by volume, but you should consult your rifle’s manual for specific load data. No specific holster, magazine, or aftermarket accessory is required for this product, as it is a consumable projectile. It is not compatible with centerfire handguns or rifles.
