Understanding the Basics: 12 Gauge Slug vs. 45-70

The 12 Gauge Slug: Shotgun Powerhouse

The 12 gauge slug is a single, large projectile designed for use in a 12 gauge shotgun. Unlike birdshot, which contains many small pellets, a slug delivers all of its energy to a single point. This makes it suitable for hunting deer, bear, and other large game within a limited range. There are two primary types of 12 gauge slugs: rifled slugs (also known as Foster slugs) and sabot slugs. Rifled slugs are designed for smoothbore shotguns and have external ribs that impart a stabilizing spin as they travel down the barrel. Sabot slugs, on the other hand, are designed for rifled shotgun barrels. They consist of a smaller, high-velocity projectile encased in a plastic sabot, which separates from the projectile upon exiting the barrel.

The effectiveness of a 12 gauge slug depends heavily on the type of slug, the range, and the shotgun used. While offering significant power at close ranges, their accuracy and effective range are generally less than that of the .45-70.

The .45-70 Cartridge: A Legacy of Stopping Power

The .45-70 Government cartridge is a centerfire rifle cartridge developed in 1873 for the U.S. Army’s Springfield Model 1873 rifle. It quickly gained a reputation for its substantial stopping power, making it a favorite among buffalo hunters and frontiersmen. The .45-70 typically fires a large-diameter, heavy bullet at moderate velocities. Modern .45-70 loads are available in a wide range of bullet weights and designs, catering to various hunting applications. The .45-70’s straight-walled cartridge design makes it suitable for lever-action rifles, contributing to its enduring popularity. Its inherent accuracy and ability to deliver devastating energy downrange have cemented its place in shooting history.

The .45-70 is known for its ability to take down large game at moderate ranges. While not a flat-shooting cartridge, its trajectory is manageable with proper sighting and practice. Its versatility and historical significance make it a compelling choice for hunters and shooting enthusiasts alike.

Ballistics and Performance: A Head-to-Head Comparison

Velocity and Energy

Velocity and energy are critical factors in determining a round’s effectiveness. Generally, the .45-70 offers a flatter trajectory and higher retained energy at longer ranges compared to a 12 gauge slug. A typical 12 gauge slug might have a muzzle velocity of around 1500-1800 fps, delivering approximately 2500-3000 ft-lbs of energy at the muzzle. A .45-70, depending on the load, can achieve similar or even higher muzzle velocities and energy levels. High-performance .45-70 loads can push a 325-grain bullet to over 2000 fps, generating upwards of 3500 ft-lbs of energy.

* **12 Gauge Slug:** High energy at close range, significant drop-off at longer distances.
* **.45-70:** Better retained energy and flatter trajectory at extended ranges.

Trajectory and Range

The trajectory refers to the path of the bullet or slug in flight. A flatter trajectory allows for easier aiming and greater accuracy at varying distances. The .45-70 generally exhibits a flatter trajectory than a 12 gauge slug, making it more forgiving when estimating range. Rifled slugs, in particular, suffer from significant bullet drop beyond 100 yards. Sabot slugs offer improved trajectory compared to rifled slugs but still fall short of the .45-70’s performance.

Effective range is another crucial consideration. While a 12 gauge slug can be effective out to 100 yards or so, the .45-70 can reliably reach out to 200 yards or more, depending on the load and shooter skill. Experienced hunters often prefer the .45-70 for its ability to deliver accurate shots at longer distances.

Accuracy

Accuracy is paramount for ethical and effective hunting. The .45-70, especially when fired from a quality rifle with a good scope, is capable of excellent accuracy. Many shooters can achieve sub-MOA (minute of angle) accuracy with the .45-70, meaning they can consistently place shots within a one-inch circle at 100 yards. 12 gauge slugs, on the other hand, are generally less accurate. Rifled slugs, fired from a smoothbore shotgun, may only achieve 4-6 inch groups at 100 yards. Sabot slugs, fired from a rifled shotgun barrel, can improve accuracy to around 2-4 inch groups at the same distance.

* **12 Gauge Slug:** Acceptable accuracy at close range, but degrades quickly at longer distances.
* **.45-70:** Superior accuracy, especially with a quality rifle and proper load selection.

Recoil

Recoil is a significant factor to consider, especially for inexperienced shooters. Both the 12 gauge slug and the .45-70 produce substantial recoil, but the perceived recoil can vary depending on the firearm, the load, and the shooter’s physique. Generally, the .45-70 tends to have a sharper, more concentrated recoil, while the 12 gauge slug delivers a broader, more spread-out recoil impulse.

Many shooters find that the recoil of a .45-70 is manageable with proper technique and a well-padded stock. However, some high-powered .45-70 loads can be punishing, even for experienced shooters. Similarly, the recoil of a 12 gauge slug can be significant, especially in lightweight shotguns. Recoil pads and proper shooting form can help mitigate the effects of recoil and improve shooter comfort.

Applications: Where Each Round Excels

Hunting Large Game

Both the 12 gauge slug and the .45-70 are capable of taking down large game, but each excels in different scenarios. The 12 gauge slug is often preferred in areas where shotguns are required for hunting deer or other large game. Its close-range stopping power makes it effective in thick brush or wooded areas where shots are typically taken at shorter distances. The .45-70, on the other hand, is a better choice for hunting in more open terrain where longer shots are possible. Its flatter trajectory and superior accuracy allow for more precise shot placement at extended ranges. In our experience, both rounds can be ethically used on deer-sized game within their effective ranges.

Home Defense

While both rounds are capable of inflicting serious damage, they are generally not recommended for home defense due to the risk of over-penetration. A 12 gauge slug, in particular, can easily penetrate multiple walls and pose a danger to bystanders. The .45-70, while less likely to over-penetrate due to its slower velocity, still presents a significant risk in a home defense situation. There are more appropriate rounds for home defense that offer sufficient stopping power with less risk of over-penetration.

Target Shooting and Competition

The .45-70 is a popular choice for target shooting and silhouette competitions. Its inherent accuracy and manageable recoil (with appropriate loads) make it enjoyable to shoot at the range. The 12 gauge slug, while less common in formal competitions, can be used for recreational target shooting. However, its limited accuracy and range make it less suitable for competitive shooting.

Insightful Q&A Section

**Q1: What is the maximum effective range for ethical hunting with a 12 gauge slug on deer?**

A: While some may claim longer ranges, leading experts in 12 gauge slug ballistics suggest that an ethical maximum range for deer hunting with a 12 gauge slug is around 100-125 yards. Beyond this, accuracy and energy drop off significantly, increasing the risk of a non-lethal hit. It’s crucial to practice at various distances to understand your personal limitations and the performance of your specific slug and shotgun combination. In our experience with 12 gauge slug hunting, responsible shot placement is paramount.

**Q2: How does barrel length affect the performance of a .45-70 cartridge?**

A: Barrel length significantly impacts the .45-70’s velocity and, consequently, its energy and trajectory. Shorter barrels (e.g., 16-18 inches) will generally result in lower velocities compared to longer barrels (e.g., 22-26 inches). This is because the powder has less time to burn completely and propel the bullet. While shorter barrels offer increased maneuverability, they come at the cost of reduced ballistic performance. According to a 2024 industry report, a 4-inch reduction in barrel length can decrease velocity by as much as 100-150 fps, depending on the load.

**Q3: Are there any specific 12 gauge slug loads designed for rifled barrels?**

A: Yes, sabot slugs are specifically designed for use in rifled shotgun barrels. These slugs consist of a smaller-diameter projectile encased in a plastic sabot. As the sabot travels down the rifled barrel, it engages the rifling, imparting a stabilizing spin to the projectile. Upon exiting the barrel, the sabot separates from the projectile, allowing it to fly accurately towards the target. Sabot slugs generally offer superior accuracy and flatter trajectories compared to rifled slugs fired from smoothbore barrels.

**Q4: What are the key differences between hard cast lead bullets and jacketed bullets in .45-70 loads?**

A: Hard cast lead bullets are typically made from a lead alloy that is harder than pure lead. They are often used for hunting large game because they offer excellent penetration. Jacketed bullets, on the other hand, consist of a lead core encased in a copper or other metal jacket. Jacketed bullets tend to expand more reliably upon impact, creating a larger wound cavity. The choice between hard cast and jacketed bullets depends on the intended application and the desired balance between penetration and expansion.

**Q5: How does the weight of a 12 gauge slug affect its recoil and trajectory?**

A: Heavier 12 gauge slugs generally produce more recoil than lighter slugs. This is because more energy is required to propel the heavier projectile. Heavier slugs also tend to have lower velocities and more pronounced bullet drop at longer distances. Lighter slugs, on the other hand, offer flatter trajectories and less recoil but may not deliver as much energy on target. The ideal slug weight depends on the intended application and the shooter’s tolerance for recoil.

**Q6: Can the .45-70 be safely fired in older rifles?**

A: This is a critical safety concern. Not all .45-70 rifles are created equal. Older rifles, particularly those manufactured before the late 19th century, may not be able to handle the higher pressures generated by modern .45-70 loads. It is essential to determine the safe pressure limits of your specific rifle before firing any ammunition. Consult with a qualified gunsmith if you are unsure about the suitability of a particular load for your rifle. Using low-pressure “cowboy action” loads is generally recommended for older rifles.

**Q7: What type of scope is best suited for a .45-70 rifle used for hunting?**

A: A low- to medium-power scope with a wide field of view is generally ideal for a .45-70 hunting rifle. Scopes in the 1-4x, 2-7x, or 3-9x range are popular choices. A wide field of view is important for acquiring targets quickly in close-range hunting situations. A ballistic reticle or adjustable turrets can be helpful for compensating for bullet drop at longer distances.

**Q8: How do I properly sight in a 12 gauge shotgun with slugs?**

A: Sighting in a shotgun with slugs requires a stable rest and a methodical approach. Start by shooting at a target at 25 yards to establish a baseline. Adjust the sights or scope as needed to move the point of impact closer to the center of the target. Gradually increase the distance to 50 yards and then 100 yards, making further adjustments as necessary. Be sure to allow the barrel to cool between shots to prevent heat-related accuracy issues. Repeat this process with the specific slugs you intend to use for hunting, as different loads can have different points of impact.

**Q9: What are some common mistakes to avoid when hunting with a .45-70?**

A: One of the most common mistakes is underestimating the bullet drop at longer distances. The .45-70 has a significant arc trajectory, so accurate range estimation is crucial. Another common mistake is using too much magnification on the scope, which can limit the field of view and make it difficult to acquire targets quickly. It’s also important to practice shooting from various field positions, such as standing, kneeling, and prone, to be prepared for any hunting scenario. Finally, always ensure you’re using ammunition that is appropriate for your rifle’s pressure limits.

**Q10: Are there any states or regions where one cartridge is preferred or required over the other for hunting specific game?**

A: Yes, hunting regulations vary significantly by state and region. Some states may restrict the use of rifles for deer hunting, requiring hunters to use shotguns with slugs or muzzleloaders instead. Other states may have minimum caliber or energy requirements for hunting certain game animals. It is essential to consult the specific hunting regulations for the area you plan to hunt to ensure compliance with all applicable laws.
