Dropped a feral hog(200lbs) @ 85 yds w/the .454 and thereafter in the following deer season another feral (150 lbs) with the .454-also a spike offhand @75 yds and a BucK(my first w/ a handgun) @ 100yds. The .454(Freedom Arms) was scoped w/ a leupold 2X)-plenty for south Texas. Used a HDY 250g XTP load over 33.7g of H-110 and srm primers from CCI. This is plenty for me.
45ACP in a 1911. There is a huge (325+pounder) mount on my buddies living room wall that he killed with one shot from his 45 at slightly under 25 yds. If I knew that was his gun of choice I would have made him take a SBH as backup. I guess it wasn't necessary tho. He hunted on a game ranch down in Southern Texas. Chief aka Maxx Load
With the .454, you have the option of shooting .45 Colt ammo - from mild for plinking to pretty darn hot for hunting. A reasonably stout .45 Colt load will do the job on a pig.... save the .454 stuff for big bears or a trip to Africa.
I voted for the .475 Linebaugh...because I wanted to. But with handguns, I've used the .41 Mag, .44 Mag, .45 Colt, .454, .475L, .50 AE, and .500 WE on hogs. With rifles, the .308 and .338 Wins and the .300 Weatherby ( at long range in N.Z.)
All those hogs died! Nothing is really any better than the .44 Mag.
