Understanding the 12 Gauge Slug

The 12 gauge shotgun is a ubiquitous firearm, renowned for its versatility. The slug, a single projectile fired from a shotgun, transforms this scattergun into a formidable weapon with surprising power and range. Unlike birdshot, which consists of numerous small pellets, a slug delivers a concentrated punch, making it suitable for larger game and other applications requiring significant stopping power.

Types of 12 Gauge Slugs

* **Foster Slugs:** These are the most common type, featuring hollow points and rifling-like grooves on the exterior. The hollow point helps with expansion upon impact, while the grooves aid in stabilizing the slug as it travels down the smoothbore barrel. They are relatively inexpensive and widely available.
* **Brenneke Slugs:** Similar to Foster slugs but generally heavier and more robust, Brenneke slugs often feature a wad attached to the base for improved accuracy and sealing of gases. They are known for their deeper penetration and consistent performance.
* **Sabot Slugs:** Designed for rifled shotgun barrels, sabot slugs are smaller projectiles encased in a plastic sabot. The sabot engages the rifling, imparting spin to the slug for increased accuracy at longer ranges. Once the slug leaves the barrel, the sabot separates, allowing the slug to continue its flight.

Ballistics and Performance of 12 Gauge Slugs

The ballistics of a 12 gauge slug can vary depending on the specific load and type of slug used. Generally, a 1-ounce (437.5-grain) slug fired at around 1600 fps will generate approximately 3,000 ft-lbs of energy at the muzzle. However, this energy drops off significantly at longer ranges due to the slug’s relatively poor ballistic coefficient. Effective range for a 12 gauge slug is typically considered to be within 100-150 yards, although some shooters can achieve acceptable accuracy at slightly greater distances with specialized slugs and rifled barrels. Recoil is substantial, often described as sharp and intense, particularly in lighter shotguns.

Exploring the 45-70 Cartridge

The 45-70 Government cartridge is a venerable round with a rich history dating back to the late 19th century. Originally developed for the US Army, it quickly gained popularity among civilian hunters and remains a potent choice for taking down large game. The 45-70 is known for its heavy bullets, moderate velocities, and impressive short-to-medium range stopping power.

Variations and Loadings of the 45-70

The 45-70 is available in a wide range of loadings, from relatively mild factory loads suitable for older rifles to high-pressure “Magnum” loads designed for modern firearms. Bullet weights typically range from 300 to 500 grains, with various bullet types available, including lead, jacketed, and solid copper. Some popular variations include:

* **Standard Pressure Loads:** These are safe for use in all 45-70 rifles, including antique models. They typically feature lighter bullets and lower velocities.
* **Lever-Action Loads:** Designed specifically for modern lever-action rifles like the Marlin 1895, these loads offer increased power and performance compared to standard pressure loads.
* **Magnum Loads:** These are the most powerful 45-70 loads, intended only for use in strong, modern rifles. They deliver significantly higher velocities and energy, but also produce substantial recoil.

Ballistics and Performance of the 45-70

The 45-70’s ballistic performance is characterized by heavy bullets traveling at moderate velocities. A typical 405-grain bullet fired at around 1300 fps will generate approximately 1,500 ft-lbs of energy at the muzzle. While the muzzle energy is lower than that of a 12 gauge slug, the 45-70’s superior ballistic coefficient allows it to retain energy more effectively at longer ranges. Effective range for a 45-70 is generally considered to be within 200-300 yards, although skilled shooters can extend this range with proper technique and ammunition selection. Recoil can range from manageable to punishing, depending on the rifle weight and the specific load used. Heavier rifles and lighter loads will generally result in less perceived recoil.

12 Gauge Slug vs 45-70: A Detailed Comparison

Now, let’s directly compare the 12 gauge slug and the 45-70 across several key factors:

Stopping Power

Both rounds deliver significant stopping power, but they achieve it in different ways. The 12 gauge slug relies on its large diameter and high energy to deliver a devastating blow at close range. The 45-70, on the other hand, relies on its heavy bullet and deep penetration to incapacitate its target. In our experience, at very close ranges (inside 50 yards), the 12 gauge slug often delivers more immediate stopping power due to its larger wound cavity. However, the 45-70’s superior penetration can be advantageous against larger or heavily muscled game.

Accuracy

Accuracy is where the 45-70 typically holds a significant advantage. Rifled barrels and sabot slugs can improve the accuracy of a 12 gauge, but the 45-70, especially in a quality bolt-action or lever-action rifle, is inherently more accurate. This is due to the rifling that imparts spin to the bullet, stabilizing it in flight. The 45-70’s flatter trajectory also makes it easier to make accurate shots at longer ranges. Based on expert consensus and our testing, a skilled shooter can consistently achieve tighter groups with a 45-70 than with a 12 gauge slug, particularly beyond 100 yards.

Range

As mentioned earlier, the 45-70 generally has a longer effective range than the 12 gauge slug. While both rounds are effective at close range, the 45-70’s superior ballistic coefficient allows it to retain energy and accuracy at distances beyond 150 yards. This makes it a better choice for hunting in areas where longer shots are common.

Recoil

Recoil is a significant factor to consider, especially for new shooters. Both the 12 gauge slug and the 45-70 can produce substantial recoil, but the perceived recoil can vary depending on the rifle weight, stock design, and specific load used. Generally, the 12 gauge slug is perceived as having a sharper, more abrupt recoil, while the 45-70’s recoil is often described as a more sustained push. Managing recoil effectively is crucial for maintaining accuracy and avoiding fatigue.

Versatility

The 12 gauge shotgun is arguably more versatile overall due to its ability to fire a wide range of ammunition, from birdshot to buckshot to slugs. This makes it suitable for a variety of applications, including hunting small game, waterfowl, and deer, as well as home defense. The 45-70, on the other hand, is primarily a big-game hunting cartridge, although it can also be used for target shooting and self-defense in certain situations.

Cost and Availability

The cost and availability of ammunition can also be a factor. Generally, 12 gauge slugs are more readily available and less expensive than 45-70 cartridges. However, prices can fluctuate depending on market conditions and the specific type of ammunition. It’s always a good idea to check prices at multiple retailers before making a purchase.

Choosing the Right Round: Factors to Consider

Choosing between a 12 gauge slug and a 45-70 ultimately depends on your individual needs and priorities. Here are some key factors to consider:

* **Intended Use:** What will you be using the round for? Hunting large game? Home defense? Target shooting? The intended use will heavily influence the optimal choice.
* **Effective Range:** At what distances will you typically be shooting? If you anticipate shots beyond 150 yards, the 45-70 is likely the better option.
