Shotguns for hogs is a bad idea here, they get over 700 lbs in my neck of the woods, just imagine buckshot or slugs hitting that hide/scar tissue. I have heard countless stories of hogs being killed and old buckshot is found just under the hide or loged in it. These are tough customers especaly the larger boars, and nothing out of a shotgun penatrates enough for my likeing on them. A 30-30 with a good fusion/corelock will knock a hole through his vitals and is much more handi in the brush, same with a Saiga loaded with 150gr spire points. If you have to use your shotgun I would get the hardest heaviest slug I could find to ensure penatration to the vitals. Your 44 mag is an exellent backup just don't buy CXP2 grade hollow points for hogs if you think you might see a large one. Some people use hard cast bullets in 44s others like heavy controled expansion bullets either one should work just fine for you.
