Speer DeepCurl 38 Cal 158 Grain Bonded JHP Bullets (Box of 100)

Speer DeepCurl 38 caliber 158 grain bonded JHP bullets are engineered for handgun hunters and serious reloaders who demand reliable expansion and deep penetration on game. Built using Speer's electrochemical bonding process, these hollow points fuse the jacket to the lead core at a molecular level—eliminating jacket separation and ensuring consistent performance shot after shot. If you're loading ammunition for .38 Special or .357 Magnum hunting loads, DeepCurl bullets deliver the controlled expansion and weight retention that separate ethical, effective hunting rounds from generic range ammo.

The pre-formed petals on these projectiles are the key to their reputation. Rather than relying on random jacket fracturing, the petals expand in a predictable, repeatable pattern. That consistency matters when you're waiting for the right moment on a whitetail or hog—you need to know your bullet will perform the same way every time the trigger breaks. The bonded construction means you'll retain enough bullet weight to drive deep into the vitals, even after passing through heavy hide and bone.

Each box contains 100 bullets, so you have plenty of inventory for load development, practice, and hunting season. Whether you're a dedicated handgun hunter refining loads for your 10mm backup or working up potent .357 Magnum rounds for your lever gun, these are the kind of bullets that reward precision in your reloading process with real-world performance in the field.

Frequently Asked Questions

What's the difference between Speer DeepCurl and standard hollow point bullets?

DeepCurl bullets use an electrochemical bonding process that fuses the jacket to the lead core. This prevents jacket-core separation, ensures consistent expansion through pre-formed petals, and delivers higher weight retention than traditional hollow points. The result is more reliable penetration and repeatable performance on game.

Can I load these for both .38 Special and .357 Magnum?

These are .38 caliber (.357") bullets, so they are compatible with both .38 Special and .357 Magnum handguns and lever guns. Always consult published load data for your specific combination of powder, primer, and brass.

How many bullets come in a box?

Each box contains 100 bullets.

Are these bullets suitable for hunting?

Yes. The bonded construction, controlled expansion, and deep penetration characteristics of DeepCurl bullets make them well-suited for handgun hunting applications where reliable performance on game is critical.
