Description
The CorBon 45 Colt +P 225gr DPX load is built for shooters who want a proven 45 Colt +P round from a company that helped shape modern high-velocity handgun ammunition. Each box holds 20 cartridges loaded with a 225 grain DPX solid copper hollow point bullet rated at 1200 feet per second, producing about 720 foot-pounds of muzzle energy. The DPX bullet is a solid copper hollow point made by Barnes, so it opens into sharp petals while keeping nearly all of its weight, with no lead core that can separate from a jacket.
This 45 Colt 225 grain solid copper load is rated from a 7.5 inch barrel and loaded to +P pressure, so it is meant only for modern revolvers and rifles built to handle it.

Why Choose the CorBon 45 Colt +P 225gr DPX
- 225 grain Barnes solid copper DPX bullet
- Rated 1200 fps muzzle velocity, 720 ft-lbs energy
- Retains nearly all of its weight for deep, consistent penetration
- Designed to perform through heavy clothing and barriers
- 20 rounds per box, item DPX45C225/20
Built for Personal Protection
- Carry and home-defense handguns chambered in 45 Colt +P
- Shooters who want a high-velocity defensive load
- Practice sessions to confirm point of impact with your carry ammo
- Keeping one consistent lot of ammo in your carry gun and range bag
Before you trust any new defensive load, fire at least 50 to 100 rounds through your handgun to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Rotate your carry ammo every so often, and store the rest in a cool, dry place in the original box so the cartridges stay clean and easy to identify by lot number.
Check with your firearm maker before using any +P 45 Colt load, and practice with the CorBon 45 Colt +P 225gr DPX before you rely on it. Confirm your point of impact from a steady rest and get comfortable with the recoil of a full-power load.

Why Choose CorBon 45 Colt +P Ammo
A solid copper bullet holds its weight as it expands, so it can drive deep through heavy clothing, barriers and bone. At a rated 1200 fps and 720 foot-pounds, the CorBon 225 grain DPX turns the 45 Colt into a capable load for personal defense and for medium game where legal.
When you compare 45 colt self defense ammo, remember that +P 45 Colt loads exceed standard pressure and are meant only for strong modern firearms. This load pairs well with the Ruger Redhawk, Super Redhawk and New Model Blackhawk in 45 Colt, 454 Casull revolvers and modern lever-action rifles rated for +P. Never fire it in Single Action Army style revolvers, older guns or reproductions.
CorBon has built high-velocity defensive ammunition in South Dakota since 1982, when the company set out to solve a common problem: hollow points that plugged with clothing and failed to expand. That focus on real-world performance is still at the heart of every box. Corbon 45 colt +p ammo is loaded to tight standards so shot-to-shot velocity stays consistent, which helps you build confidence in the same load you train with and carry.
Owners of heavy-frame 45 Colt and 454 Casull revolvers who want one load for defense and the outdoors will find this a versatile choice. Always confirm your firearm is chambered for 45 Colt +P, wear eye and ear protection, and follow all federal, state and local laws.
