Description
Cor-Bon's approach to self-defense ammo is straightforward: load it hot and design the bullet to perform. This 10mm 165-grain JHP does exactly that, combining high velocity with a hollow point that's been refined over decades of testing and real-world feedback.
The Cor-Bon 10mm 165gr Expansion Design
The JHP bullet uses internal and external serrations paired with a soft lead cavity that promotes rapid, controlled expansion. Cor-Bon ran extensive ballistic gelatin tests to dial in this load, and the 1250 fps muzzle velocity ensures the bullet opens up reliably without excessive over-penetration. Most loads in this weight average 9 to 15 inches of penetration in gelatin, which keeps energy transfer focused downrange.
Flash-Suppressed Powder and Scored Jackets
This round uses flash-suppressed powder to reduce muzzle flash, important if you're defending yourself in low-light situations. The bullet jackets are skived and scored to ensure uniform expansion under pressure, so you get consistent terminal performance from round to round. That consistency matters when you're relying on this ammo to perform.
Built for Reliable Feeding and Reloading
The ammunition comes in reloadable brass cases with non-corrosive Boxer primers, so if you reload, you can stretch your investment. The round chambers smoothly in 10mm pistols and feeds without fussing. This is new production ammo made to consistent standards, which means your carry load stays reliable whether you bought your box last month or last year.

Frequently Asked Questions
What makes Cor-Bon JHP ammunition different from other self-defense rounds?
Cor-Bon built its reputation on high-velocity defensive loads. The 10mm 165gr JHP uses flash-suppressed powder and scored jackets designed for reliable expansion while limiting over-penetration. Extensive ballistic gelatin testing by the manufacturer ensures the bullet performs as intended across a range of barrier conditions.
Will this 10mm ammunition function reliably in all 10mm pistols?
This is new production ammo loaded to standard 10mm Auto specifications and designed for reliable feeding in modern 10mm handguns. That said, it's always a good idea to test a box through your specific pistol before relying on it for carry, since different firearms can be picky about ammunition.
Can I reload the brass from Cor-Bon ammunition?
Yes. The ammunition comes in reloadable brass cases with standard Boxer primers, so you can reload the cases after firing. Just follow standard 10mm reloading practices and let your equipment and powders guide you.
How much penetration should I expect from the 10mm 165gr JHP?
Cor-Bon's testing shows this load typically penetrates 9 to 15 inches in ballistic gelatin, which strikes a balance between sufficient depth and controlled expansion. Penetration can vary depending on barriers like clothing, but the scored jacket design helps manage this variation.
