Description
The DoubleTap 10mm 180gr Colt Defense JHP load is built for shooters who want more from their 10mm Auto than typical factory ammunition delivers. DoubleTap loads a 180 grain Colt Defense jacketed hollow point to a rated 1150 feet per second, producing about 529 foot-pounds of energy from a 5 inch barrel. In testing, DoubleTap reports about 16 inches of penetration with .75 inches of expansion. Made by DoubleTap under the Colt Defense Ammunition name, this 180 grain load uses the traditional 10mm bullet weight in a hollow point built for reliable defensive performance.

DoubleTap offers many 10mm loads, from the fast 125 grain solid copper hollow point to the heavy 230 grain hardcast solid, so this Colt Defense 180 grain JHP fits right in the middle as an all-around carry round.
Buying ammunition by the box from the same production lot keeps velocity and point of impact consistent from one range trip to the next. Keep a record of the load you carry, check your ammunition for dents or loose bullets from time to time, and rotate your carry rounds so the ones in your firearm stay fresh. These simple habits help you get the full performance DoubleTap builds into every cartridge.
Before you trust any new load, fire enough rounds through your firearm to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Full-power loads produce more recoil and muzzle blast than typical range ammo, so practice with the DoubleTap 10mm 180gr Colt Defense JHP until you are comfortable with it, and store the rest in a cool, dry place in the original box.

Why Choose DoubleTap 10mm Ammo
The 180 grain bullet is the original 10mm weight, known for deep, reliable penetration. DoubleTap rates this Colt Defense load at 1150 fps and 529 foot-pounds from a 5 inch barrel and about 1100 fps from a compact Glock 29, with about 16 inches of penetration and .75 inch of expansion in testing.
When you compare 10mm self defense ammo, penetration in the 12 to 18 inch range with reliable expansion is what many shooters look for. This 10mm 180 grain hollow point sits right in that window, and it is a natural match for the Colt Delta Elite, the Glock 20 and 29 and other 10mm handguns.
DoubleTap Ammunition is an American company known for loading popular calibers to their full potential, especially the 10mm Auto and other magnum handgun rounds. Doubletap 10mm ammo is loaded with quality components and brass cases, and many shooters choose it when they want the performance a caliber was designed for rather than a reduced-power range load.
Concealed carriers, home-defense shooters and 10mm owners who want a proven 180 grain defensive load will find this a strong choice. Always confirm your firearm is chambered for 10mm Auto, wear eye and ear protection, and follow all federal, state and local laws.
