A point to ponder
How can a HP be expected to work right in all conditions?
Lets say its summer, and your target is wearing nothing but a t-shirt. A HP is expected to expand and penitrate, OK lets say it works. Fine.
Now take the same round, same target, only its winter and the target has on a heavy down coat. How can you expect the bullet to work the same way, expansion and penitration.
Or let say, you have two targets, One is skinny, one is rather Fat, Again how can you expect the bullet to work the same on both targets?
I'm no engineer, but I can THINK. I've been to enough autopsies to know no two bullets react the same way, even the same bullets out of the same gun hitting the same target.
Below is a picture I took of shooting a Black Hills 125 Grn HP, +9 and a Lvman 358477 150 grn SWC, (range lead) pushed by 4.5 grns of 231. I shot them into wet phone books. I also used the same bullets fired at a dry phone book. I didnt take pictures because I couldnt find the HP, it didnt open and went through the book altogether. The SWC had slight damage and almost made it completely through the book.
Whats the answer, GOT ME, I use SWCs, they seem to work more constantly. I've finished off several moose (from moose-vehicle accidents when I was in LE) with SWCs out of a 4 in Model 28 Service Revolver, never had to shoot one twice. I've also finished off deer while hunting with my 642 using SWCs (the same load as listed above), Based on my experience I'll stick to my SWCs.
BUT, to each his own. If everyone liked the same thing, there would only be one bullet out there and we wouldnt have anything to talk about.
