Speer Bullets 9mm 115 Grain TMJ - 100 Count Box (355 Diameter)

Whether you're loading 9mm ammunition for the range or building reliable carry rounds, Speer Bullets 9mm 115 Grain TMJ offers the kind of consistency and cleanliness that serious reloaders expect. These 355-diameter bullets use Speer's Uni-Cor technology, which completely encases the lead core in a seamless jacket—eliminating the exposed lead you'll find in conventional full metal jacket designs. The result is ammunition that's safer to handle, cleaner to shoot, and easier on your equipment and health.

The Uni-Cor construction does more than look neat on the bench. By sealing the lead core completely, you get more uniform bullet diameters and consistent heel geometry that chambers reliably and groups tighter than loose-tolerance alternatives. That consistency matters whether you're fine-tuning loads for a 9mm competition gun or building defensive rounds. And since there's no exposed lead—either in the box or in the smoke downrange—you reduce the fouling that slows down your shooting day and the airborne lead exposure that comes with conventional bullets.

This is a 100-count box, so you get enough to load a full testing session or work up a solid batch of practice or carry ammunition. Reloaders who've moved away from basic FMJ often find that the cleaner-shooting, more consistent performance of a totally-enclosed jacket pays dividends in accuracy and repeatability—especially once you settle on your powder and primer combination.

Frequently Asked Questions

What's the difference between Speer TMJ and standard FMJ bullets?

Speer's TMJ uses Uni-Cor technology to completely encase the lead core in a seamless jacket. Standard FMJ bullets leave lead exposed at the base. This design makes TMJ cleaner to shoot, more consistent in diameter and heel geometry, and reduces both fouling and airborne lead exposure.

Will these work in my 9mm reloader setup?

Yes, these are 355-diameter bullets, which is the standard specification for 9mm reloading. Always confirm compatibility with your specific reloading manual and equipment.

How many rounds does one box load?

Each box contains 100 bullets, so one box will load 100 rounds of 9mm ammunition.

Are these appropriate for defensive or carry ammunition?

These are component bullets for reloading. If you reload your own carry ammunition, work with published load data and follow all safe reloading practices. Always test thoroughly before carrying any handloaded ammunition.
