Which bullet for hogs

[8X56MS]

I hunt hogs in South Fl, North Fl, and in Georgia. I have had the best results with a Marlin 1894, and hand loaded Speer 270 GDSPs. Thirty Thirty works well, with the 170 grain Remington CoreLokt bullets. Recently, I have been converted, and will be using my Springfield M1A SOCOM with an EOTech holo red dot sight. Wow, talk about a Hog gun !
Note that all three of these are larger caliber guns than the .243 Win. There is a reason. While head shots, and such can work, its rare that you get an ideal shot. Most of the time, where I hunt, its dark, in thick cover, and your shot is usually a quick shot at a running animal. The smaller rifles just don't cut it for me.
