Nothing works well on running hogs. They are pretty tough and have a lot of relatively empty space inside so it's all about shot placement with them. If you don't hit them in the CNS they tend not to drop when hit. They may die later and often do, but not on the spot
Once the shooting starts it's not easy to make precise hits which is why I prefer low recoil semi autos with good magazine capacity. I hunt with a 6.5 Grendel, my buddy uses Hornady Black 69gr 223. Within 100 yards we have about the same first round DRT rate as each other. Many people scoff at 223's but in my experience they are as effective as most anything else I've seen. Getting precise hits while they are in freakout mode is not nearly as easy as it seems
Do you already have a PVS14 and/or IR laser? What about thermal? There are advantages and disadvantages with each, and different styles of hunting
Thermal is the most effective for target acquisition and ID for hogs but NV is definitely better for navigation and movement. If you will be hunting from a static position it may be simpler to get a decent thermal and skip the PVS14 but if you are stalking on foot you'll need a 14 for sure. Arfcom always says get both and in this case I agree
For me it's way more fun to hunt with both. Scanning and engaging with the rifle thermal, general observation and movement with the 14. We do a fair bit of walking and get a lot of use out of both
I live in Houston and I don't think there is any place around the area to hunt hogs...you'll need to get a couple hours out, or know someone with a hog problem in the rural areas. East Texas is definitely overrun but I don't see anyone advertising they need help
See if @tmm1270 can lend any advice. He is one of the most knowledgeable pig hunters on the board for sure
