The Sierra Sports Master 40 S&W/10mm Auto 165 grain JHP bullets deliver the performance serious handloaders need for competition shooting, duty carry development, and high-power pistol work. Built with a jacketed hollow point design, these 165 grain projectiles are engineered to meet demanding velocity and accuracy requirements—particularly valuable for IPSC shooters chasing "major" power factor with 40 S&W and 10mm loads. With 100 rounds per box, you get quality Sierra construction at a practical reloading volume.
Introduced in 1992, the Sports Master line has proven itself across decades of competition and field use. The 165 grain weight strikes a balance in both calibers: heavy enough to achieve major power factor thresholds in 10mm Auto and 40 S&W with moderate velocities, yet responsive enough for practical shooting applications. These bullets reward consistent handloading and proper die setup—plan your load development accordingly and you'll find reliable, repeatable performance.
Because these bullets feature no cannelure for roll crimping, take care when selecting or adjusting your reloading dies; you may need to modify your crimping approach depending on your press setup and the specific dies you're using. If you're working with 38-40 Winchester (38 WCF) for Cowboy Action Shooting, note that while these bullets can physically work in that caliber, they are not legal for sanctioned competition. Check your local match rules before committing to a load.

Frequently Asked Questions
Can I use these bullets for IPSC competition?
Yes. The 165 grain Sports Master design meets IPSC requirements for "major" power factor in both 40 S&W and 10mm Auto when loaded to 1000 fps muzzle velocity or higher—well within reach for both calibers. Verify current match rules with your local club.
Do these bullets have a cannelure for roll crimping?
No. These bullets have no cannelure, so you'll need to plan your crimping strategy carefully. Depending on your press and dies, you may need to adjust your setup or use different crimping techniques. Discuss your specific reloading die configuration before starting a load.
What about using these in 38-40 Winchester?
While the 165 grain bullet can physically be used in 38-40 Winchester (38 WCF), it is not legal for Cowboy Action Shooting competition. These bullets work best in 40 S&W and 10mm Auto where they are purpose-designed.
How many bullets are in a box?
Each box contains 100 bullets, a practical quantity for handloaders developing loads or managing consistent supply for regular shooting.
