240 grn Impala bullets at 950 m/sec .416 Rigby

15 October 2007, 16:25

Gentlemen

This is what a 240 grn Impala Solid will do to an Impala and a baboon.

Vo 950 m/sec.

These animals where shot by a friend that I load for.

Cheers,

I'm assuming that it's the exit hole in the impala. Those are some biiiiig holes.

Hi Jeff

I use monolithic solids all the time from 7mm to 458 all travelling at quite high velocity but they dont do this kind of damage. Looking at the shape and weight of the impala bullet I would say they tumble immediatly on hitting the beast similar to a military FMJ.
Not great for the meat hunter or where deep straight line penetration is required.

This makes me wonder about a 230-grainer in the .395 Tatanka at 3100 fps.

MarkH,
Yep some tumbling going on there, with very rapid "energy dump."
Those military rules for FMJ's are so humane, eh?

Andre',
Dare I say "thanks for sharing?"

Yes I do.
The critters shown did not suffer. That is obvious.
But, definitely not the best "meat load," eh?

Hallo Andre,

You might wnat to to see

The Impala i great for BIG bore rifles if you want to make them more flat shooting.
The .416 Rigby loaded with Impala has balistic like a 300 win mag.

Meat load schmead load

When hunting for sport more death is better

Looks interesting.
However for personal hunting I make my own bullets.

If I could get a hold of some SF exploding .50 cal BMG bullets I would load them in my .500 Jeffery

Overkill from sweden

What the fu*k..
How is it possible for ANY bullet in ANY caliber to make that wound channel in the impala??
What would a 200 grain impala at 3500FPS in a .378 Weatherby do??

//OK

I wonder what a Chevrolet Impala 1962 would have looked like if hit by a 200 grain Impala at 3500FPS in a .378 Weatherby

I can assure you that this is not what happens on a larger animal however. In 2005 I shot a Cape Eland with Jaco Human, using Jaco's Sako .375 H&H and 200 grain Impala's.

Here's the entrance wound:

Here's the exit wound:

The distance the bullet has to travel in an impala is alot less than an eland. In all probability the bullet exited backwards having travelled through 180o rotation first.
Having said that dead is still dead

Gentlemen

My friend shot more the 70 animals on his safari. All where shot with Impala bullets in gis .416 Rigby. His camera was broken on the 2. day and no more pictures of game was taken.

The bullets performed perfectly. These where the "funny" pictures. Sorry if I gave the wrong impresion of the bullets. They normally give a small exit would like on the eland above.

What are these projectiles made of?

I looked at the web page but did not see this info.

AndrÃ©,

I don't have an explicit photograph but with the same load and rifle I also shot a jackal at very close range, probably 20 yards or less. The jackal was facing me and I shot it in the chest, exit through a hind leg. Basically the jackal split in two from the shot with results very similar to the photographs you show above.

Alf... I know you are smarter than I but I think speed is pretty important... or we would have to get throwing licenses.

Full mount was not an option I guess?

Speed is a poverfull factor.

Just getting a nice pelt wasn't easy. It's still kind of raggedy.

The dictum of "speed kills" has been disproven to be myth!

The fact that you have a highly unstable bullet combined with higher velocity than usual gives a massive TC just prior to or around point of exit on animals of a certain size thus these massive exit wounds.

( By varying velocity in stable bullets ie round steel spheres, because by definition they are stable in dense targets, we see that the higher the velocity goes the PC does not increase for tissues of primary visco-elastic or primary cohesive biomechanical property. IN fact the PC remains constant in size. The TC does get bigger but as this does not necessarily equate to any damage upping velocity alone as a factor is deemed a moot excercise. )

That is the point. I shot two shots 8x68S with Impala on ballistic jelly.

Twice the bullet left the straight way and tumbled. No need for this.

To keep on the path of the straight and good the bullet needs to be shorter with a flat nose to become shoulder stabilised. No way can that happen with the impala bullet.
The only thing it can do reliably is tumble.

I agree that tumbeling are a bad thing and that a bullet should keeps it direction.
The Impala does however offer a fast bullet for BIG kalibers, and gives a .416 Rigby a very flat tajectory.
I have never hunted with the Impala bullet myself, just loaded them for my friend.
Like I said earlier, about 80 animals where shot with these bullets and they where very deathly in effect. It did NOT give exit wounds like that on the majority of the animals shot.

Cheers,

AndrÃ©
