I've got a whole cigar box full of before and after bullets (different calibers..rifle and pistol) where I used to do alot of bullet expansion/penetration testing.
I mostly just used a stacks of water soaked phone books tied together..not flesh and bone but it'll work..LOL..easy to recover them too.
Was out there puttering around in my building tonight I picked out two random examples..
a 12guage shotgun slug (.700) vesus a 44magnum pistol bullet(.429).. that rose petal jacket of this Remington bullet allow it to really open up..not to mention the hollow point design.. of course the 1oz slug pentetrated more phone books..but not that much more..it's pushing against a bigger area..
I've only shot one buck with a shotgun slug..he ran about 50yards before he politely keeled over..just a thumbsized clean hole straight thru him..unlike other deer I've shot with hi-powered rifles that went down on the spot (or within a 10 yard circle)..who had a small hole going in and a big hole coming out..
just fyi..fwiw..
PS..I use Nosler partition bullets when hunting deer.. more on them later..they're high dollar but they do exactly like they're supposed too.. mushroom AND hold together for deep penetration..
