Description
Atomic's 45 ACP +P ammunition pairs match-quality accuracy with proven defensive performance. Each round features a 230 grain bonded match hollow point bullet loaded to a measured 1000 fps, delivering 511 foot-pounds of energy from real-world firearms.
The bonded construction means the jacket stays fused to the core throughout impact. Testing shows these rounds expand to approximately .80 inches and penetrate 15+ inches of ballistic medium while retaining virtually all their original weight. That combination of controlled expansion and deep penetration is what makes this load effective without excessive over-penetration concerns.
Where Atomic stands out is their testing philosophy. Instead of relying on laboratory test barrels, they gather ballistic data from common guns that people actually own and carry. This real-world approach means the performance specs you're reading come from guns like yours, not inflated lab numbers that don't translate to field performance. The rounds come in nickel-plated brass, which cycles smoother than standard brass and is reloadable if you're into handloading.
This is 50 rounds per box, 10 boxes per case. Remember that +P ammo requires a barrel rated for +P pressure specifications.

Frequently Asked Questions
Can I use this ammunition in any 45 ACP pistol?
Not all. The +P designation means higher pressure than standard 45 ACP. Your pistol must be rated for +P ammunition. Check your manual or contact the manufacturer. Standard 45 ACP guns may experience damage or unsafe function with +P loads.
How does bonded hollow point construction affect performance?
The bonded jacket stays attached to the lead core during expansion and penetration, maintaining the bullet's integrity. This prevents jacket separation and helps achieve that 99% weight retention, which translates to deeper, more reliable penetration through barriers.
Is this load suitable for defensive carry?
Yes. The controlled expansion, deep penetration, and consistent performance from real-world testing make it a legitimate defensive choice. The bonded construction and nickel-plated brass also reduce feeding reliability concerns you might see with other loads.
What makes Atomic's ballistic testing different?
Atomic tests ammunition in actual firearms people own and use, not test barrels. This gives you ballistic data that reflects real performance instead of inflated numbers from specialized lab equipment. That's why their velocity and energy specs translate to actual results in your gun.
Can I reload these brass cases?
Yes. The nickel-plated brass is reloadable. Just make sure you're following proper reloading procedures for +P specifications if you're loading your own ammunition.
What's included in a case order?
Each case contains 10 boxes of 50 rounds each, for a total of 500 rounds. This is the standard case quantity for ammunition purchases.
