I have taken hogs with all 3 of these rifles.......
R to L = Wasr10/63, SAI M1A-A1, M14S Tanker.
Wasr10/63 :
This is my beater/truck/quad/el-cheapo gun. Reliable, easy to hump around, cheap to keep it fed (7.62x39mm), nice and compact, etc......
Not my dedicated hunting rifle, and use it only if I have a chance meeting with a hog while tending other chores. 3 hogs with this to date. All inside of 100yds and usually moving. Usually run Wolf or Brown bear through it simply because this fodder is the most economically priced. Iron sights only. Makes for decent practice at hitting fast moving targets.
Not very fond of the AK types as I do not care for their iron sights or ergonomics. I picked it up rather cheap from an ole boy who was selling it on account of all the bad stuff he was reading about them on the net. (go figure). The wife actually wanted it, but she grew bored with it and gave it to me.
M1A-A1 : I have used this rifle on several hog dumping excursions before. Run it with iron sights only, and using optics mounted up on a Bassett rec mount. Usually keep it for the more open areas where I hunt. ( I baby the thing too much according to the wife...lol)
I'vs used several different loads through this rifle,( 7.62x51mm and 308) but the one that she really likes = 168gr HOR TAP. ( Expensive, but alot of fun)
M14S Tanker : This rifle was my "purpose build rifle for general purpose utility". My version at least. The mount = ARMS#18 split rail, and have dumped several hogs with it..using iron sights as well as an optic. ( Longest shot measured out at 376yds deep using a Simmons 3-9x32 Deerfield Scope, zeroed at 300yds. Load used was FED 168gr OTM M852) I prefer precision/shot placement for personal reasons.
Also dump um up close with iron sights. The front sight is a SEI Gas lock hooded front sight, and makes for an excellent way to hit them little fast movers in close for me. When I get back home, I plan to try out them Barnes Triple shocks, (if my rifle likes um)....... as I have heard good things about this particular bullet.
There is a large selection of rifles/shotguns/handguns out there for a body to choose from. My suggestion would be for you to handle a few of interest to see which feels right for you. If the budget for such a firearm exists in your camp, then some might be eliminated from your list for this reason alone. I prefer 308/7.62x51mm, but there is a wide range of calibers to choose from when it comes to a hog hunting adventure. If possible, get in some trigger time behind a few different chambered firearms of interest....and go from there. You may find that you shoot a specific firearm/caliber combination better than another.
Good luck with your research.
