Speer Bullets 45 Caliber 230 Grain TMJ (Total Metal Jacket) - 451 Diameter

If you're loading .45 ACP for competition, practice, or duty use, Speer Bullets' 45 Caliber 230 Grain TMJ rounds deliver the consistency and reliability that handloaders depend on. The 230-grain weight is the standard for full-power .45 loads, offering proven ballistics and stopping power in a Total Metal Jacket design that's cleaner to shoot and easier on your firearms than exposed-lead alternatives.

These 451-diameter bullets are built with Speer's Uni-Cor technology, a process that bonds the lead core directly into the jacket during manufacturing. The result is a bullet that won't separate under pressure, shoots with exceptional uniformity, and won't leave fouling residue in ported compensators or suppressors—a real advantage if you're running any kind of muzzle device. The bullets are swaged twice to ensure a consistent heel and precise diameter, shot-to-shot accuracy that translates to tighter groups and more predictable performance at the range or in the field.

Whether you're a high-volume reloader stocking up for regular practice or a precision handloader fine-tuning loads for your carry gun, these TMJ bullets offer the build quality and consistency you expect from Speer without the mess and toxicity concerns of bare lead. They're a smart choice for indoor ranges, law enforcement training, or anywhere cleaner ammunition handling matters.

Frequently Asked Questions

What .45 guns will these bullets work in?

The 451-diameter sizing is standard for .45 ACP pistols. These are suitable for any firearm chambered in .45 ACP that you're handloading for.

Are these safe to shoot indoors or in enclosed ranges?

Yes. The Total Metal Jacket design encases the lead core completely, making them much cleaner to handle and shoot than bare-lead bullets. They're a good choice for indoor ranges and environments where lead exposure is a concern.

Will these work in compensators or suppressors?

Yes. The Uni-Cor construction and full jacket prevent fouling in ported compensators and won't deposit lead residue in suppressors, unlike exposed-lead bullets.

What's included—is this a loaded round or a component?

These are bullets only—a reloading component. You'll need to provide your own brass, primer, and powder to assemble complete cartridges.
