In response to your range question, i own a sam yang .45 that has taken several deer from 30 to 90 yards with 143 grain round balls. Rifle is dead on to 65 yards then starts to drop a lot. At 90 yards the rifle drops almost 2 feet. The rifle will launch a 143 grain .457 round ball 900 feet per second at the muzzle. I have not hog hunted with it but, i would feel comfortable on a hog up to 65 yards. I dont know about the other cals. But, would vouch for the .45.
Mr. Dan mcvey, owner of xp airguns, then resealed by will piatt at saddle mountain gunsmith a couple years later. My first two shots are only 15 feet per second apart. I have owned several different big bores but, have stayed true to the sam yang.

Assuming brain shots, little difference between the calibers on any hog; more a matter of correct ammo choice with any of those calibers.
Assuming chest shots, I'd gravitate toward the .45 or .50 for larger hogs... but strongly recommend educating yourself on big-bore airgun ballistics and the advantages and disadvantages of different projectiles.

I have limited experience with cast bullets in a sam yang .45 because all i have tried have either been too loose or too tight. The best i can guess for my rifle would be a fairly soft .456 slug. The horniday .457 r.balls seem to be the right fit and weight for deer but, i have only taken one with a body shot, that shot was at 50 yards thru heavy cedar limbs which resulted in a almost full pass thru. The ball was lodged just under the hide on the opposite side. I took a head/neck shot on one in a open power line at 90yards. I elevated a foot over the head, the deer was standing broadside looking at me, and the ball hit 6 inches below the head directly in the throat, which also broke the neck. It was a medium size 8 point buck, that dropped where it stood. I was amazed on that shot. If i could keep my shots on a hog within 50 yards with that rifle, i would love to try a 250 grain, or so mr. Hollow point cast slug on the hogs body.
