Frequently Asked Questions
Hornady .45 ACP Ammo for Sale
What is the best 45 Auto ammo?
"Best" depends on your use. For self-defense, Federal HST and Speer Gold Dot 230gr are trusted by law enforcement. For range shooting, standard 230gr FMJ works fine. Our marketplace lists 31 variants typically around $28.74, with options from $19.76 to $479.68 across 37 retailers.
Is 45 Auto the same as 45 ACP ammo?
Yes, .45 Auto and .45 ACP are identical cartridges. ACP stands for Automatic Colt Pistol. Both names appear on ammunition boxes and refer to the same round with identical dimensions and performance.
What is the best Hornady ammo for self defense?
Hornady Critical Defense and Critical Duty are the top choices. Critical Defense suits concealed carry with reliable expansion through clothing. Critical Duty handles barrier penetration better, making it ideal for duty use. Both use FTX bullets designed for consistent performance. Prices typically run around $28.74 per box across 31 available variants.
Is .45 Auto or .45 ACP better for hunting?
.45 Auto and .45 ACP are identical cartridges—different names for the same round. It handles small game and coyotes well, and some hunters use it successfully on deer at close range, though opinions vary. For more versatility, .357 Magnum or .44 Magnum remain popular hunting choices.
What is special about Hornady black ammo?
Hornady Black ammunition is designed specifically for modern sporting rifles and functions reliably across multiple platforms—direct impingement, gas piston, suppressed, unsuppressed, bolt, and pump actions. It uses Hornady bullets optimized for accuracy and consistent ballistics, making it a versatile choice for shooters who demand reliable performance across different rifle setups.
What's the difference between Hornady Black and Custom?
Hornady Black features versatile loads optimized for excellent performance from America's favorite guns broadly, not tuned to specific gas systems or action types. Custom focuses on hunting and target shooting with traditional load development. Black uses distinctive black packaging; Custom uses standard Hornady packaging.
Is FTX better than Hollow Point?
FTX is Hornady's hollow point design with a flexible polymer tip that initiates reliable expansion and prevents clogging. It generally expands more consistently than traditional hollow points, especially through barriers. Neither is universally "better"—performance depends on your firearm, barrel length, and intended use.
