good article on stopping power...this has been a big topic my brothers and I have discussed many times...
this is how I see it for a most centerfire rifle.. More speed and weight contributes to more energy...If there is an exit wound then the deer, animal, or object did not absorb all the energy. if there is no exit wound then all that energy was absorbed which contributes to killing power and this had to of created quite a bit of damage but there must be penetration to consistently have killing power...penetration ensures that the vital organs have been penetrated and destroyed. there are other variables involved, but this is it in a nutshell... and it works best when the cartridge is matched to the game that is hunted...
an exit wound is ok if the majority of the bullet has broken off in fragments as well as expanded as it travels through the cavity...the bullets entry, path thru the cavity, as well as the exit should resemble two funnels attached together with the small ends facing outward.
on the 22 mag the only way to penetrate the skull on a big hog is to use solid bullets and penetration is what kills with this caliber when talking big hogs and not so much about expansion...it's a challenge but makes it a little more exciting...and the dogs are at a lower risk of getting shot as well and the gunfire noise is a lot less compared to that of a larger caliber hand gun... my 2 cents worth
