What is a Slug Gun?

A slug gun is basically a shotgun that uses a different kind of projectiles than normal shotgun cartridges. These guns shoot slugs instead of metal BBs. That’s where the name comes in.

A slug is more like a bullet used in handguns and rifles. The benefit of using slugs is that they improve the pinpoint accuracy of your shotgun. Buckshot cartridges spray an array of pellets towards the targets, which is not very effective at long range. Plus, they don’t allow for a humane kill of a game at distant range. On the other hand, a slug acts more like a bullet and allows you to hit a target at a specific point.

Using slugs in your shotgun requires adding a choke. A choke is mounted towards the muzzle end of the barrel and it controls the bore diameter, so the slug can be propelled precisely. Slug guns are mostly used for hunting deer and animals of similar size.

What is the Effective Range of a Slug Gun?

The effective range of a slug gun depends upon the type of barrel and slug you are using. A rifled or non-rifled slug projectile, when shot from a smooth bore shotgun, can be accurate up to a range of 75 yards.

On the other hand, a slug fired from a rifled bore shotgun generally has an effective range of about 100-120 yards. If you move a step ahead and use sabot slugs in a rifled barrel, you can improve the effective range of your slug gun to around 200 yards or so. The difference in all the values of the effective range is the type of slug and barrel you are using.

However, for the sake of simplicity, a simple slug in a smooth bore is dead-on accurate up to 50 yards.

Perks of Having a Top Notch Scope on a Slug Gun

Having a good scope on your slug gun has its own advantages. The very first is accuracy. Shotguns are known to be not-so-accurate. Slug guns are more accurate than shotguns, and adding a scope makes their accuracy even better.

The second benefit is the range. Adding a scope to your shotgun allows you to shoot targets at a distance. This lets you shoot targets from cover, especially game like deer or turkey, which are extremely attentive toward their surroundings.

Having a good scope on your slug gun also stills your confidence. You can be more affirmative about hitting a target from a distance with a scope mounted on your slug gun when compared to bead sights.

Having a top-notch scope on your slug gun also helps you improve your scorecard in competitions. Good optics sight a clear image of your target, which eventually helps you hit targets with accuracy. Furthermore, if you are using slug guns for hunting, a good scope also ensures that you make a humane kill by hitting game in the right spot.
