45 ACP Hunting Ammo

The 45 ACP is primarily a defensive pistol cartridge and is generally considered marginal for hunting anything larger than varmints or small feral hogs. While it cuts a massive .452 caliber hole, its low velocity and low kinetic energy make it unsuitable for general deer hunting. Typical 45 ACP hunting bullet weights range from 185 to 255 grains, achieving muzzle velocities between 850 and 1,050 feet per second. This yields a starting muzzle energy of 350 to 500 foot-pounds, which is well below traditional hunting rifle standards. Because the heavy bullets shed velocity immediately and drop rapidly, the absolute maximum practical hunting range for the 45 ACP is firmly capped at 35 to 50 yards.

What Makes 45 ACP Suitable For Hunting

The 45 Automatic Colt Pistol (ACP) was engineered over a century ago for military sidearms, prioritizing stopping power on human targets at close range. It relies entirely on bullet mass and a wide frontal diameter to cause damage, as it generates zero hydrostatic shock.

For hunting, the 45 ACP is suitable only in highly specific, short range scenarios. It is popular among hunters checking trap lines, dispatching wounded game, or shooting feral hogs over bait at distances of 20 to 30 yards. When fired from a Pistol Caliber Carbine (PCC), the cartridge gains a slight velocity bump and offers much better practical accuracy, making it a viable brush gun for small game and pests. However, hunters must strictly manage their expectations: the 45 ACP is not a deer rifle substitute, and utilizing it on medium game requires perfect shot placement with specialized ammunition.

Best 45 ACP Bullet Weight For Hunting

Selecting the proper bullet weight for 45 ACP hunting involves balancing velocity for expansion against mass for penetration.

185 to 200 grain: The lighter end of the spectrum. These bullets are pushed to higher velocities (often 1,000 fps in +P loads), which helps initiate expansion in hollow points like the Hornady XTP. They are best suited for coyotes, raccoons, and small pests.
230 grain: The standard weight for the caliber. While excellent for personal defense, standard pressure 230 grain hollow points often lack the energy to penetrate deeply on tough game like feral hogs. If using 230 grain bullets for hunting, they must be +P rated to ensure adequate penetration.
255 grain: The undisputed best weight for hunting tough animals with a 45 ACP. These are almost exclusively heavy hard cast lead bullets designed for maximum straight line penetration. They sacrifice speed (roughly 900 fps) but carry incredible momentum to crush through hog shields and shoulder bones.

Best Bullet Type For Hunting

Ammunition selection is critical. The vast majority of 45 ACP ammunition on the shelves is designed for personal defense against humans and will fail miserably on game animals.

Hard Cast Lead: The absolute best choice for hunting hogs or carrying for woods defense. These solid lead bullets feature a wide flat nose (meplat) that cuts a clean hole. Because they do not expand, they penetrate incredibly deep.
Jacketed Hollow Points (XTP): Bullets like the Hornady eXtreme Terminal Performance (XTP) are designed for controlled, delayed expansion. They penetrate deeper than standard defensive hollow points before mushrooming, making them suitable for coyotes or very close range shots on thin skinned game.
Solid Copper Monolithic: Copper bullets like the Barnes TAC-XPD provide reliable expansion while retaining 100 percent of their weight. They offer excellent penetration without the risk of lead fragments in the meat.
Standard Defensive Hollow Points (Avoid): Ammunition like Federal HST or Speer Gold Dot is engineered to open rapidly and stop inside 12 to 18 inches of ballistic gel. On a feral hog, these bullets will explode on the thick shoulder gristle and fail to reach the vitals.

45 ACP Hunting Ballistics

Because the 45 ACP is a low pressure cartridge firing a heavy, blunt bullet, its ballistic trajectory degrades extremely fast.

Note: The following data represents average specifications fired from a 5 inch handgun barrel with a 25 yard zero.

Underwood 230gr XTP +P (Hollow Point)

Muzzle: 1,000 fps / 511 ft-lbs
25 Yards: 955 fps / 466 ft-lbs
50 Yards: 915 fps / 427 ft-lbs
Bullet Drop @ 50 Yards: -2.1 inches

Buffalo Bore 255gr +P (Hard Cast Flat Nose)

Muzzle: 925 fps / 484 ft-lbs
25 Yards: 895 fps / 454 ft-lbs
50 Yards: 870 fps / 428 ft-lbs
Bullet Drop @ 50 Yards: -2.5 inches

If utilizing a 16 inch Pistol Caliber Carbine, hunters can generally add 100 to 150 fps to the muzzle velocities listed above, which slightly flattens the trajectory and pushes muzzle energy closer to 600 ft-lbs.

45 ACP Effective Range For Hunting

The effective range of the 45 ACP on live game is strictly capped at 35 to 50 yards.

Ethical hunting requires enough kinetic energy to drive a bullet through vital organs. The 45 ACP starts with very low energy (typically under 500 ft-lbs). By 50 yards, the bullet is dropping fast and has lost significant momentum. Trying to shoot a feral hog or a coyote past 50 yards with a 45 ACP handgun or carbine is highly unethical, as the bullet will likely lack the energy to cause rapid expiration, leading to a wounded and lost animal.

Standard Pressure vs +P 45 ACP For Hunting

For hunting applications, +P (Overpressure) ammunition is highly recommended.

Best Barrel Length For 45 ACP Hunting

Because the 45 ACP uses extremely fast burning pistol powders, it does not benefit drastically from long rifle barrels the way magnum pistol cartridges do.

4 to 5 inches (Handguns): The standard length. A 5 inch barrel (like a full size 1911) burns all the powder efficiently and provides a decent sight radius for 25 yard shots.
8 to 10 inches (Large Format Pistols / SBRs): The ballistic sweet spot for the 45 ACP. This length extracts the maximum possible velocity from the cartridge without adding unnecessary friction.
16 inches (Carbines): Firing a 45 ACP from a 16 inch rifle barrel provides a marginal velocity gain of about 100 to 150 fps over a handgun. The true advantage of a 16 inch carbine is not ballistic power, but practical accuracy. The shoulder stock and longer sight radius make hitting a 50 yard target vastly easier than using a handgun.

Game Size And Hunting Conditions

The 45 ACP has a very narrow window of practical hunting applications.

Feral Hogs: It is frequently used for close range hog eradication. Using 255 grain hard cast ammunition from a treestand at 20 yards will easily punch through a hog’s shield and anchor the animal.
Varmints and Predators: Excellent for raccoons, possums, and coyotes at close range. Standard 200 grain XTP hollow points are highly effective here.
Whitetail Deer (Highly Discouraged): Hunting deer with a 45 ACP is illegal in many states due to its low kinetic energy. Even where legal, it is considered unethical by most hunters unless used at point blank range (under 25 yards) by a highly skilled marksman using +P hard cast ammunition. The 45 ACP lacks the hydrostatic shock required to reliably drop a deer quickly.

Shot Placement And Bullet Performance

Because the 45 ACP moves so slowly, it will not create a massive temporary wound cavity like a rifle bullet. It relies entirely on crushing tissue directly in its path.

When hunting hogs with hard cast lead, hunters should aim for the ear hole to disconnect the central nervous system, or take a strict broadside shot through the shoulders to break the skeletal structure. If utilizing hollow points on coyotes or small game, broadside heart and lung shots are required. Quartering shots with a 45 ACP hollow point should be avoided, as the bullet lacks the energy to traverse the entire length of the animal to reach the vitals.

Best 45 ACP Hunting Loads

Based on ballistic output and specialized bullet construction, these are the top choices for hunters:

Best for Hogs and Deep Woods: Buffalo Bore +P 255gr Hard Cast Flat Nose. The undisputed king of 45 ACP penetration. It hits incredibly hard and will not deform on heavy bone.
Best Hollow Point for Medium Targets: Underwood +P 230gr XTP. Uses the tough Hornady XTP bullet pushed to maximum safe velocities to ensure deep penetration before controlled expansion.
Best for Standard Pressure: Federal Solid Core 225gr. If your gun cannot handle +P loads, this polymer coated hard cast bullet offers excellent penetration at standard velocities.
Best Lead Free Load: Barnes VOR-TX +P 185gr TAC-XPD. Solid copper construction guarantees maximum weight retention and beautiful six petal expansion on thin skinned game.

FAQs

Is 45 ACP good for deer hunting?

No, it is highly marginal for deer hunting and illegal in many states. It lacks the kinetic energy and hydrostatic shock required for clean, ethical harvests on medium game.

Can you hunt hogs with a 45 ACP?

Yes, but only at very close ranges (under 30 yards) using heavy, +P hard cast lead bullets that can punch through the hog’s thick shoulder shield.

What is the effective range of a 45 ACP for hunting?

The ethical effective range is 35 to 50 yards maximum. Past 50 yards, the heavy bullet drops aggressively and loses the necessary energy for vital penetration.

What grain 45 ACP is best for hunting?

For tough animals like feral hogs, a 255 grain hard cast bullet is best. For lighter thin skinned game like coyotes, a 200 to 230 grain tough hollow point (like the XTP) is preferred.

Does a 16 inch barrel make a 45 ACP better for hunting?

A 16 inch Pistol Caliber Carbine improves practical aiming accuracy significantly, but it only adds roughly 100 to 150 fps in velocity because the fast burning pistol powder is optimized for short barrels.

Is +P ammo safe to use for hunting?

Yes, provided your specific handgun or carbine is rated by the manufacturer to handle +P (overpressure) ammunition. +P ammo is highly recommended for hunting to maximize velocity and energy.

How much energy does a 45 ACP have at 50 yards?

A high quality +P hunting load will retain roughly 400 to 450 foot-pounds of energy at 50 yards, which is considered very low for medium game hunting.

Final Verdict

Is the 45 ACP good for hunting? The 45 ACP is a highly capable defensive cartridge that doubles as a close range tool for small game, varmints, and pest eradication. It is best suited for hunters dispatching raccoons, coyotes, or feral hogs at distances under 35 yards.

The ideal hunting ammunition is a +P rated 255 grain hard cast bullet for deep penetration, or a tough 230 grain controlled expansion hollow point like the XTP. Its major advantages are its massive frontal diameter, suppression capabilities, and compatibility with fast handling Pistol Caliber Carbines. Its primary limitations are abysmal kinetic energy, a severely restricted 50 yard range, and the fact that standard defensive ammunition will fail on thick skinned animals. If you want a quiet, heavy hitting brush gun for close range pests, the 45 ACP works; if you intend to hunt deer or shoot past 50 yards, you must choose a true magnum handgun or rifle cartridge.
