AR-15 .223 Hog hunting update

After a few more hunts and four more dead hogs shooting a Daniel Defense M4 platform with a few modifications and shooting Hornady Full Boar .223 ammo I have a few observations. First to put my comments in context, I typically hunt public lands and hunt well off the beaten track, often walking for miles through swamps and hammocks, stalking hogs. The M4's light weight , and carbine length, lends itself to the type of hunting I do.

• The DD M4 platform is an excellent hog carbine when modified with a good trigger and low power, fast optic.
• The optic I chose is a Steiner 1-4 power with an illuminated reticle. The scope is bright in low light, has good eye relief and an adjustable red dot reticle. I found it relatively easy to stay on running hogs through the swamp. 
• Trigger: I chose a a 3.5 pound CMC trigger. It was an easy drop in installation and breaks very clean and resets lighting fast. And at about $160 its a good value. 
• Light: I installed a basic Streamlight forward on the M-Lok rail where it is easy to turn on and off.

Impressions of the Hornady Full Boar .223 ammunition:
PRO's:

• It's an impressive load, fast, accurate, with good penetration, expansion and devastating wound channel.
• You still need decent shot placement for a kill.
• The low recoil allows you to stay on fast moving targets and fast follow up shots.

CON's:

• This is a light load, too light for less than ideal shot placement.
• I would not want to test this load against a large charging boar.

Lessons learned:

• The M4 carbine properly set up can be an effective easy and enjoyable to hunt hogs with, and well suited to the walk and stalk / still hunting.
• The largest hog I killed was just over 200 pounds and it took two shots on the run to take him down. 
• Smaller hogs can be taken down with one well placed shot.
• It would be wise to carry a large caliber side arm if things go sideways with a large hog.
