The heavier bullet is close to the ballistics of a 20 ga slug.
(W/ a JSP instead of pure lead you could almost have a six shot 20 ga slug gun on your hip. This would assume you'd do some research on the expansion charctersistics. Roughly figured, the .480 @ ~ 25% expansion would yeild close to .6 of frontal area. @ 425 gr, it's close to the 437 gr of a one ounce 12 ga slug. Even if it doesn't expand, it's still punching nearly a half inch hole.)
Most people fail to make the connection to just how close the hyper-bores are to a slug gun.
(The lighter one isn't really in the same class. Still,,it's a Barnes. Barnes makes good stuff. If it were me, and I was hunting a bear (or in my case-probably a boar) I'd probably consider the Barnes. It it was a case of the bear (or boar) hunting me,,,hands down I'd want the heavy.)
