Speer
Speer 50 Cal 300 Grain TMJ bullets are built for reloaders who need reliable, hard-cast projectiles for big-bore rifle applications. At .500 diameter and 300 grains, these Total Metal Jacket rounds deliver the consistency and durability that serious handloaders demand, whether you're working up precision loads or preparing ammunition for hunting or range shooting.
Speer's Uni-Cor manufacturing process sets these bullets apart. Molten lead is poured directly into the jacket, completely encasing the core in a flawless metal envelope. That design means the bullet base resists deformation under firing pressure, and you get a cleaner, more predictable load every time. Double swaging ensures uniform heel geometry and precise, consistent diameter across every round in the box—no sorting, no surprises.
These TMJ bullets are engineered to work cleanly in all your equipment. Because they're fully jacketed, they won't foul ported compensators, keeping your firearm running smooth and your loads repeatable. At 300 grains, they're substantial enough for the .50-caliber cartridges favored by long-range hunters and precision shooters. This box of 50 gives you a solid foundation for developing accurate, dependable ammunition.
| Caliber | .50 |
| Weight | 300 Grains |
| Diameter | .500 |
| Bullet Type | Total Metal Jacket (TMJ) |
| Quantity | 50 per box |
| Manufacturing Process | Uni-Cor (molten lead core, direct jacket encapsulation) |
Total Metal Jacket means the lead core is completely enclosed in a copper jacket—not just around the sides, but at the base as well. This design prevents lead exposure, reduces fouling in your firearm, and ensures consistent performance. TMJ bullets are ideal for shooters who want clean, reliable ammunition without worrying about lead contamination or ported-compensator fouling.
These bullets are .500 diameter. Always verify that your specific cartridge and firearm are compatible with 300-grain projectiles before loading. When in doubt, consult your reloading manual or manufacturer specifications for your exact caliber and chamber.
Uni-Cor is Speer's proprietary process where molten lead is poured directly into the bullet jacket, creating a seamless bond with no air pockets or voids. This produces a flawless jacket and a base that resists deformation under pressure, giving you more consistent ballistics and longer component life.
This product contains 50 bullets per box.
