Having grown up in So. Tx and shot hogs with everything from 22LR to .338 Lapua and .300 Win Mag to bow and arrow. I have have to agree that placement IS everything. I have shot well over 500 hogs all over the US and carried a Ruger 3 Screw 44 mag as back up with 250 grn Keith Style GCLSWC over 2400 powder and they CRUSHED hogs!! More times than not, they blew threw them.
I now have a 460 S & W and am planning on a hunt in So. OK in Feb and will take some pork then and my son will be shooting my .460 and 7mmBR pistols.
