Explosive...No. We don't use exploding bullets. But varmint bullets are designed to be frangible. The fact that they vaporize a groundhog or prairie dog just proves the point we are trying to make. They are designed to come apart on contact in a short distance after impact. Thus not being able to retain weight for penetration. This is good on an animal that is a few inches to 14 inches wide, not for bigger bodied animals. Period.
I have never seen a gopher "Vaporized". I've shot a LOT of them with the same loads I used on deer. They come apart pretty good, but it ain't vapors, it's chunks, and it's the logical extension of a high energy transfer into an area that is essentially larger than the critter you hit with it. Now when you take it under due consideration that I (and several other CGN'ers) have killed more than one gopher at a shot, we can reasonably say that there is some energy not transferred to the first gopher hit, yeah? I got three off one mound one day. It was...messy.
A deer isn't smaller than the affected area.
If we look at the size of a groundhog as being about the margins between blowing it apart and not, and superimpose the affected are into a carcass the size of a deer, you still get penetration, expansion, and an energy dump, and I really don't give a damn HOW superfrangibleexplosivevarminatorblasteringest you bullets are, they are not going to 'blow up on the skin, and leave a bruise'
Smack that same bullet into the ribcage of a deer and open up a 4 or so inch diameter cavity in behind it, plus the residual energy being spent by the still moving bullet parts, and you have a right messy, right dead, deer.
Just how far into a deer did you figure you needed to go to reach the heart anyways? About 6 inches. Less for the lungs, or the liver. Oh yeah, mine, this year, somewhat better than 12 inches total, with pretty good odds of exit-ting the deer had the parts not hit the leg bone
Put that many foot pounds of energy into a ribcage, and you get burger, not a bruise. Deer are not made of steel plates, but you'd never know that by the way some dudes go on. Sideways, end facing the wrong way, or point-on, equals hole and messy inside bits.
rral22, there IS no PROOF of problems here, only opinions, mostly by folks with strong beliefs and no experience whatsoever to back them up.
My money is on that the OP's deer was not hit by the bullet, where he thinks it was hit. But that's just a theory, and I cannot prove otherwise nor will anyone prove otherwise to me, without having the opportunity to pick over the carcass and be involved with the skinning and butchering.
I have seen enough problems that should not have happened to not be convinced that more hand holding is the answer.
Maybe I need a 25-20 for next year. The internets all say it won't kill a deer either!
