Big bores are a blast (literally!) at close ranges!! I took a nice 150 lb boar last year with a 45-70 gov. 405 grn flat nose at less than 50 yards. Square hit behind the shoulder.

I thought for sure that this gun would make a hog cut a flip when hit, but feral hogs are a breed of their own. He ran about 70 yards into a gawd-awful briar thicket before he expired. That rifle is still my go-to hog gun. I lost a hog after shooting one with a .223 almost straight down from a treestand. Tought me a lesson about missing vitals from that angle. That probably would not have happened if I had been shooting the 45-70.

All that being said, that .450 or .458 you have, should make it a fun hunt!

This is all I've ever needed. 220 grians of pure death!

.243 with 100gr Sierra Game Kings will kill any Hog on this planet!

Go the .270 with the 140gn sierra game king in hollow point they are dinomite on pigs and deer and also roos if they are a problem.

I agree the .270 is the right caliber.
