I'm gonna rattle off some things I thought about. No particular order of importance.
Things I do now. Some lessons came way faster than others:
Use a replaceable scalpel blade knife to get through the hide, so I didn't dull my processing knifes. Hog hair is some edge ruining stuff!
Use a 308 WIN semi auto rifle. I used .223/5.56 AR15 first couple years. The round will kill, but if one don't hit perfectly, they'll think they missed them. I was all confident on the first few hogs I shot on the run with one-shot drops, until I found a hog 1/2 mile away bleeding out all its natural orifices and 7 .223 bullet holes. 308 will anchor them or drastically slow them down, even if the shot is off vitals. (I say 308 WIN, but really something bigger than 5.56)
Use the shot placement illustrated by Zen Archery video. I shot at shoulders for 20yrs. I got lucky I think 90% of the time shooting on shoulder. I used 155gr Amax. I switched to 168gr Amax to reduce the low yield nuclear explosions the 155s were making. LOL
Drop the hog I'm shooting at before moving onto the next. No "flock shock" as they say in goose hunting. (Spray & pray)
Use a suppressor. However, I haven't to date because I can't own one in IL. Couldn't convince my partner all these years to buy some just to use in TX. I wear electronic muffs. Sordin Pros
Wear a lightweight pack with zip lock bags to store backstraps/loins from hogs hit miles from camp.
Bust brush and canyons with a zero-magnification red dot or use iron sights (Nothing with a magnified eye box)
Bring a rifle when blood trailing. (Hint, my video)
Understand a hog can cut through thick brush in the blink of an eye, and a 300lb hog can remain hidden at 5yds away in brush
Keep a tourniquet and first aid kit in the pack. If that sow that charged me didn't kill me, I could at least try to survive the wounds.
Use little GMRS radios for communication. Cell coverage not everywhere.
Take more videos! LOL
Be aware of the truck antennae shooting out the passenger side...
Keep a pistol as backup and keep it in an enclosed holster to keep dirt/mud from creeping into after a week in the field.
know that hogs like to follow fence lines and use prominent terrain features for navigation.
Understand I can't chase down a 5lb wee little piglet. Just get tired or bit. LOL
Itinerary
Mornings - Hogs are nocturnal and screw around all night in the fields. I hunt a field edge with tree line at my back, or with the canyon at my back with a LR 300WM rig. 07:20, where I hunt, is the witching hour! Apparently, that is when the height and angle of the Sun clicks in their brains and they go trotting back in a line to the brush or canyon for shade and water.
Mid Mornings/Early afternoons - Kit up for brush or canyon busting.
Evenings - Do a 180 degree turn from the morning hunt and wait for them to come out the canyon or bush. Truck hunt the perimeter.
Nights - Drink beer, ponder the cosmos, and talk about how cool it would be to have NV/thermal, and how we are too poor to buy them! LOL
That's my experience with hog hunting and how I go about it. LOL
