10mm Auto Ammo Prices

Born in 1983 with the Bren Ten, adopted by the FBI, then famously watered down into what became the .40 S&W. Sonny Crockett carried an early Bren 10 during the Miami Vice heyday. It was a good looking piece of engineering and helped launch the original spec cartridge.

The full-power 10mm survived the detour and came back swinging — hog hunters, backcountry carriers and semi-auto hunters keep it alive. The Glock 20 in 10mm has gained popularity as a wilderness hiking tool for bear protection replacing the .44 Mag revolver as the usual go-to.

Loads split honestly: full-power 180 to 220 grain doing .41 Magnum-adjacent work, and softer "FBI-lite" loads at 9mm prices doing range duty. Read the box carefully. The name on the case doesn't tell you which one you're getting. Prices vary widely - do your research and get the deals. They're out there.
