1.) .357 Magnum has the penetration but lacks in diameter. (2.) 10 mm , 41 & 44 Magnum...ding ding ding. 12 Gauge slug , 30-30, AK, SKS, Mosin Nagant & 8mm Mauser, M1 Garand...ding ding ding. (3.) .45acp & 45 Long Colt have the diameter but lack penetration. Why use specially loaded 45LC when the 44 mag is more proficient and efficient?
For those whom are shy about packing a semi auto pistol for wild hog....on the hazard factor scale, protecting yourself, with a pistol, from dangerous people, is much higher than any swamp meeting with porkey.
Speaking of swamps...If loose rattling fitted 1911s improved function, then thousands of IPSC & IDPA competitors would sound like squeaky front yard gates when they walk past. Loose fit does not equate optimum 1911 function. Besides, GI issue 1911s also had the reputation of be extremely inaccurate.
Your modern double action revolver is faster to load & shoot as compared with a single action revolver. Especially if you have a hand injury or if you need to shoot with non dominate hand. Revolver shooters don't have to worry about losing a magazine or chasing brass. Ruger and farmers is a match made in Haven.
Fish & Game regulations will specify if you're allowed to use full metal jacket, FMJ, ammo or not. If you can, don't be affraid to use FMJ 10mm, 41 & 44 magnum on wild hog. ComBloc Military surplus 7.62X54R and 7.62X39 will be just fine for feral Georgia farm swine as well.
