Feral Pig Hunting - Tools and Tactics of the Trade | Great Days Outdoors

As more and more people get into feral pig hunting, the most common statement I hear is “I bought a 300 Blackout AR-15 so I can kill some hogs”.  I have heard this phrase weekly, sometimes daily, since forming my wild pig hunting business, Hog Rush, LLC. I cringe when I hear this, time and time again.

Often when asked what caliber I use in my business, the question likely ends with a “300 Blackout?” What I am hearing is that the person has listened to the local gun shop counter expert who usually is repeating what he read in a sponsored gun magazine article or on the internet when it comes to caliber selection for hunting feral pigs, both of which are only backed up by manufacturer hype and advertising campaigns in an effort to enhance sales, not actual field data.

Will a 300 Blackout kill a Hog? Sure. However, it lacks the required velocity to consistently create a temporary wound cavity large enough, and penetration deep enough to make it the best choice for hunting feral pigs. 

In this article, I’d like to go over some mistakes I have made in caliber selection and other gear features that proved to be not up to what I read or heard about. Hopefully, my mistakes can be used to help you choose the right gear for the most efficient wild Hog harvest.

 

Feral Pig Hunting – Barrel Rifling Twist Rate

When a projectile enters an animal, the forces and velocity create a shock wave that opens the tissue up temporarily much larger than the projectile diameter, which causes excessive blood loss, trauma, and shock. This temporary wound cavity can be 6” or larger. So even though the actual bullet does not pass through or touch an artery or organ, the temporary wound cavity that is created by velocity, may cause damage to the artery or organ and cause instant incapacitation of the animal. Picture a mini explosion inside the animal.

Picture a mini explosion inside the animal.

In my experience, the faster the rifling twist on projectiles that impact above 2000 feet per second, the smaller the temporary wound cavity. A faster rifling twist will stabilize heavier bullets. Heavier bullets are slower. My goal when setting a rifle for hunting feral pigs is to achieve the best accuracy and the most velocity I can so that when the bullet impacts the target, it is traveling at least 2000 fps and is barely stabilized enough to remain accurate. This way the bullet will transmit most of its energy on the target, not pass through.

Think of sticking a needle into soft tissue vs. a writing pen. The overstabilzed bullet acts as the needle and the writing pen acts as the bullet that is barely stabile. The needle will poke on through easily where the writing pen will impact and yaw sideways leaving a larger hole and most likely taking a different route once inside.

A feral pig is a dense animal. Larger boar hogs have calcified fat surrounding their chest commonly called their “Shield”. This shield is similar thickness and density to a commercial 18 wheeler truck tire. To penetrate deep enough and achieve the desired 12-14 inches of penetration, you need a projectile that is traveling above 2,000 fps upon impact and has a bonded jacket and high sectional density.

In other words, the bullet needs to retain most of its weight and velocity upon impact.

Unfortunately, the 300 Blackout does not meet this criteria, and with the common .30 cal 110 grain ammunition available, most 16” barrels achieve a dismal 2100 fps muzzle velocity. Most 300BLK rifles also have a barrel with a twist rate of 1/8 to stabilize the heavier projectiles for subsonic use as well. So a lighter bullet over spins. In the field, this combination has a 50-75 yard effective range on wild hogs. Past 50 yards you will see more hogs, if knocked down, get up and run off. Why? Because the velocity upon impact did not create the temporary wound cavity large enough to incapacitate the central nervous system. Nor did the round penetrate deep enough.

My 300 Blackout example might not sit well with those who purchased a rifle chambered in that particular caliber and bought into the gun shop and magazine hype specifically for hunting feral pigs. I have seen that most occasional hunters who spend money and buy into their gear choices, cannot allow objective reasoning to override their EGO. I too was in that very position years ago and spent thousands of dollars on the 300 Blackout trying to get the caliber to live up to the hype. I had read about the caliber being the ultimate hog hunting caliber. Over 4500 wild hog rifle kills later…the 300BLK is NOT the ultimate hog hunting caliber.

 

For hunting feral pigs the small .223 can do big damage

Even a .223 with a relatively small bullet when traveling at a high velocity can do big time damage on tough feral pigs

Feral Pig Hunting – Rifle and Caliber Selection

When selecting a rifle caliber for wild hog hunting, look over the available ammunition and inspect the advertised velocity ratings and bullet composition. Calibers suited to deer hunting, might not perform well on wild hogs. Deer and other thin skinned animals, require a bullet that will expand upon impact to avoid a pass through. Wild hog ammunition needs more penetration and to expand slower. A .243 Winchester would be a good selection if you wanted to use a traditional bolt action deer hunting rifle for wild hog hunting. Most commercially available ammunition has a high velocity and low recoil to help follow up shots. A heavier .243 bullet selection would enhance the instability upon impact causing a yaw effect, creating a larger temporary wound cavity.

 

Feral Pig Hunting with an AR15 – Which Caliber?

As hunting hunting wild feral pigs becomes more popular, more people seem to gravitate to military style rifles. Since wild hogs are seen as a nuisance by most states, the weapon regulations are not as strict as other game animals. Alabama does not have a weapon or a magazine capacity restriction on weapons for hunting feral pigs. Therefore, people, including myself, choose “America’s Rifle”, the AR15.

The AR15 can be built to be as accurate as most bolt action rifles and can be chambered in numerous calibers including the before mentioned 300BLK. In my experience, the 6.5 Grendel is the best overall performer in the AR15 platform in terms of energy on target and remains supersonic and accurate out past 800 yards using the Hornady 123 grain AMAX. The 6.8 SPC is a decent round as well but does not have the ballistic coefficient like the Grendel to reach extended ranges, but out to 300 yards it is a solid choice.

I have found that the 5.56x45mm, commonly called the .223 Remington, is a great choice if the right ammunition and barrel twist rate combination is used.

Barrel twist rate you ask? Remember back when I spoke about velocity? Well the 5.56mm has velocity. With a 55 grain projectile and a 16” barrel, muzzle velocity is over 3100 fps. With that comes low recoil, a flat trajectory, and accuracy and make it a viable option for hunting feral pigs.

However, if you over stabilize the bullet using too fast of a barrel twist rate, the bullet will tend to “pin cushion” or pass through the hog leaving behind a small hole instead of that temporary wound cavity I spoke about earlier. This surely will allow the hog to run off and die a slow miserable death. For an AR-15 chambered in 5.56mm, a 1/9 twist barrel using a 55 grain bonded bullet seems to be the sweet spot for accuracy, stability, energy upon impact, and muzzle velocity. By 1/9 twist, I mean the bullet spins one complete revolution in the barrel every nine inches. If you have a 1/7 twist, the bullet spins one complete revolution in seven inches. Since most manufacturers use a 1/7 twist to stabilize bullets heavier than 69 grains, you may need to change out the barrel to a slower twist rate such as 1/9 when using lighter bullets. Heavier bullets will be slower.

a well outfitted 223 AR-15 will increase your accuracy for long coyote shots

An AR-15 .223 outfitted with the appropriate thermal optics, a suppressor and utilizing the right bullet can be an effective after hours feral pig and coyote rifle.

 

Remember, velocity incapacitates. The 5.56mm will also have a relatively flat trajectory out to 250 yards as well. So those longer coyote kills will be easier to take. Just put the crosshairs on the top of the animal’s back and squeeze. Also, on running shots past 100 yards, the 5.56mm will be more likely to connect vs. a slower running bullet.

 

Using Suppressors While Feral Pig Hunting

Commonly called “Silencers”, even by the governing body ATF, are not actually as quiet as you see in movies. Far from being silent. Unless you are shooting a .22 Long Rifle , a rifle with a silencer usually sounds similar to a .22 LR without a silencer. High velocity ammunition defeats the speed of sound, therefore the bullet flight will still have a crack sound as it travels through the air. Subsonic ammunition can be used to further reduce the sound to that of a nail gun, but it is not recommended to use for hunting as the velocity is reduced to that of a pistol and effectiveness and range are drastically reduced. The benefits of using a suppressor, are lower recoil, reduced hearing damage, and can possibly disguise your shooting position. Hog Rush, LLC. is a silencer manufacturer and uses silencers while hog hunting. Titanium silencers are almost half the weight of a comparable stainless steel version. Since each silencer requires a $200 registration tax, I always advise my customers to spend the extra money for a Titanium silencer.

The benefits are a more balanced rifle for faster and more accurate free hand shots. If you have ever walked around in the field with a rifle on a stalk, you can appreciate the lower weight as well.

 

Thermal Cameras for Feral Pig Hunting

The very first night I went hunting feral pigs at night, an older friend had invited me over. He wanted to demo one of my silencers and had some night vision equipment. He had a couple of farms he helped control the wild hogs on. I drove over one night and we went out on his golf cart in search of them, with suppressed rifles of course. The company “FLIR” had loaned out a small thermal spotter to him. The first of its kind. It was a pocket sized thermal monocular called the FLIR SCOUT RECON 320 resolution. We called it the “Golden Egg”. It was slightly larger than an egg and oh so precious. Out to 300 yards average, you could see white dots out in a field if there was something breathing out there. Good enough to make everything more efficient. It allowed you to scan with standard night vision and then identify the object.

That year we managed to harvest over 370 wild hogs using that system. Thermal to spot, night vision on suppressed rifles to shoot. It became an obsession. FLIR also had a new to the market thermal weapon sight but military only. It took some hoops to jump through, but I was able to acquire three of those units the next year and started HOG RUSH, LLC. as a night wild hog hunting guide service.

Through the years I have used most every form of night vision and thermal device on the market. As competition has grown, prices have dipped enough for the occasional hunter to acquire these items. These are good times. That same weapon sight I paid $12,000 for years ago can be bought for thousands less today and still as effective. My goal here is to help aid the prospective buyer on their decision in future articles. Check out my article: Wild Hog Hunting: How to Hunt Hogs at Night.  Look for future articles aimed at thermal and night vision specifics.

 

When to Hunt

“Outfitter (you fill in the blank), put us in a deer stand during the day and we didn’t even see a Hog.” Often times when speaking to people interested in a hog hunt with my night hunting outfit, HOG RUSH, LLC., this exact phrase is repeated. These individuals had been on a hog hunt during daylight hours as you would hunt for deer in Alabama. The frustration in their voice tells me that the guide did not understand wild hog movement patterns and/ or was lazy and simply put them out as they had done with their deer hunters which just doesn’t cut it when it comes to hunting feral pigs.

Early on, before thermal scopes came along I hunted during the day, Most of the time if I saw a hog it was in a swamp and I happened upon it while it was trying to stay cool in the shade. Hogs are similar to humans. Close enough in fact, for medical researchers to perform tests on them to help advance medicines and surgical procedures. I don’t know about you, but I like to stay cool in the hotter months. So do hogs as they do not have the ability to sweat. They tend to stay hidden during the day and feed at night when temperatures cool off.

In my experience, once the dew point hits, and the ground is wet, the chances of coming across a wild hog go way up. In Alabama, that can range anywhere from 9 pm to  3 am. During that time the hogs are looking for food and usually a farmer’s field is their dinner table. Even around cotton fields, grub worms and nut grass will draw them in. It is cooler out in the open air as well.

Hotter months from May thru October sees more consistent wild hog movement. Temperatures are more leveled out and the ability to pattern hog movement becomes easier. You might still have great movement during cooler months, but when it averages out, the better nights will be in late spring and summer.

 

Moon Phase and Weather:

I could sit here and try and describe what moon phase and weather is best, but I can only say that consistency is the key. I have had great nights in every moon phase, weather, and barometric pressure. I have also had not so good nights in similar conditions. I have data books full of what I thought would be helpful information. Unlike other animals, wild hogs seem to get out when they feel like it. Hopefully you will be there with the right gear when they show themselves.

I hope this article has been helpful and will allow you to open your mind when it comes to rifle caliber and specification selection. . Remember, accurate but barely stable. Try and turn your bullet into double or triple its size inside the animal by forcing it to turn sideways once it impacts. Heavier bullets are not always better when it comes to hunting feral pigs.
