FAQs

Can I use 10mm ammo in a .40 S&W firearm?

No. 10mm rounds are longer and generate higher pressure; they are not safe in firearms chambered for .40 S&W.

What is the typical velocity of 10mm ammo?

Velocity varies by load but typically ranges between 1,200 to 1,300 fps for 180-grain bullets.

How does 10mm compare to .45 ACP in stopping power?

10mm generally offers higher velocity and energy than .45 ACP, providing improved penetration and flat trajectory.
