hunting with cast- slow expiry?

[tokguy]

The main reason there are less drop dead in their tracks kills with cast bullets is because the velocity of the bullet is considerably slower than jacketed high velocity rounds resulting in very little hydrostatic shock. But make no mistake any critter being ventilated both sides is just as dead but possibly 50yds away.

This is about like someone saying "It's not a clip...it's a magazine!"
But it's not 'hydro static'... static means...not moving. Pressure on a column of fluid at rest.
In reality, 'hydro dynamic' would be more accurate.
Beg pardon on being particular. But it is like the word 'unthawed'...just ain't accurate for the way we use it.

Several posts above have not mentioned "spin" - I think pretty much standard 375 Win barrels are about 1:12" twist - so if muzzle velocity is, say, 2,400 fps for easier figuring, the bullet will exit muzzle at about 144,000 rpm. Not much in the flight to 100 yards is working to slow down that spin, so likely a ball park value at impact, not like velocity. What hits the "hair" on the shooter's side is not just a bullet travelling along straightly - it is also spinning axially at very high rpm, and that will likely contribute to havoc that it causes as it penetrates? If it is found within the meat, not only was the forward motion been stopped, but so was that rotation. I would suspect that a bullet that tumbles after impact, also retains some spin - or is at least loosing it as it contacts meat and moisture. I have never shot and killed an animal of deer size with a cast bullet, so I can not be very helpful to the OP's original question.

Lead hardness testers are available, and relatively cheap. I haven't hunted with cast for quite a while, but I used a wide meplat heavy for caliber bullet design (a Keith or modified Keith, usually). I don't recall the hardness number anymore, but it would bust both shoulders of a small white tail out of a 44 mag. - dan

Suprise, suprise. Not expected however this mornin a fruitful hunt an full freezer again.

soo, a bit of a truck hunt this particular deer , i'd been snoopin around likely fringe farmland for few hours from crack of dawn until t got warm an sweeaty with humidity before this storm come thru...
heading out in the ute and i drive past 2 deer an they scamper up in the woods about 50m an i drive on by , slowly in 2nd on a bush track, ... i pulled up th next corner an got out a few rounds and my model 94 an walked back up the track an had a bo peep around the corner, yeh still there an looks like hind and fawn... beauty.

snuck up a bit further an they spooked , i stood up an "mewed" at them , i was able to pull them up on the 2nd , an with that thru a tiny amount of scrub i put the now - filed down bead on the chest and 'dropped the hammer'...
DRT!?
couldnt belive that.
approx 60meters shot uphill a bit, slightly anglin away but broadside aplenty lookin at me.

got some carcass damage pics il post later too

so this is a slow load i spoke of, 20gr of 4198 an a 245gr FN hard cast.
suprised at this distance it nailed it as it did, shot placement i guess is the bottom line with that. i expected to follow it up the hill lol
it ended up a young spikey with button head, not ideal with my mantra but not wasted none the less.
