Impact test photo

[JeffinNZ]

This photo goes back about ten years but I only dug up yesterday.

Around the time of the test I worked for a company that did warehousing for a bakery product firm and one day I scored some 30-40lb slabs of bakery shortening that was being binned. I used it for impact tests.

The test pictured was at 50m and I compared a subsonic 311008 ex my .32-20 against a .22RF HVHP. I poured a thin plaster mix into the bullet holes to form a cavity cast.

The 32-20, even at subsonic, passed right through 15 inches of shortening and embedded itself in a fence post 100m behind the test.

Here is the .22RF test:

So in answer to the question of will a FN cast bullet at modest FPS have a decent terminal effect? YES.

Nice work. I believe this was the reason was the switch from 9mm to 40 by the FBI after the 1986 Miami Dunkin-Donut shootout. It was found that the standard issue 9mm would not penetrate the 15 inches of donut fry fat that the perpetrators were wearing that fateful day.

Yeah, if the po *** would just avoid the donuts, a lot of grief could be also avoided.:kidding:

[Walter Laich]

Cool. good visual representation of what happened

[Pb2au]

Thank you very much for sharing. What a clever idea.
The results are interesting!

awesome way to show expansion and wound channel

Thanks

I find it interesting that even though there isn't a lot of expansion on the 32 cal bullet, the wound channel is quite impressive...definitely large enough to humanely harvest a deer if one limits his range. It also verifies that one doesn't need a hollow point for a bullet to be effective at moderate velocities.

Thanks for sharing. Great pictures, great read, and provides insight.

Ya know Leftiye, you're stirring the poo. LOL

I'd caution against inferring clean killing capability on deer from comparing bread dough wound channels against a 22. That's not much of a yardstick.

The pictures do explain such a bullet's better killing power on the larger small game and pests over a 22, though.

Jeff, thanks for sharing.

Its interesting shooting into various test medias. I remember when our beloved Bruce B was shooting a big gun 416 Rigby or 404 Jefrys or something like that into wet rice. He slightly miscalculated the hydraulic effect.
Anyone remember the results?

Having actually killed a deer with a similar boolit/ballistics just 5 months or so ago with stellar results and a full pass through....I could not agree more......it does not take a 30-06 to kill a deer at 50-75 yards. I see cast HP's as a very limited use device and for the most part I see it as a penetration limiter. One that is simply not needed in the deer fields.

I do believe he pretty well blew the box to pieces.

[JeffinNZ]

Wow, that's an eye opener. I wouldn't have guessed that the anemic old 32-20 in subsonic form would still have that much momentum after penetrating that stuff.

Neither did I. It was a wake up call when I heard it hit something solid and then worked out it was the fence post 100 yards further on. Went about 1 inch into the pine.

That was it! Never underestimate the hydraulic effect of any bullet catching media containing water, as in flesh.

[Digital Dan]

Interesting methodology for illustrating the effect on target media, though I think the comparison is misleading. The .22 obviously expanded, but the .32-20, we don't know. Doubt that it did in a significant fashion. Penetration is largely a function of momentum and RETAINED sectional density. Low velocity RN rimfire bullets will penetrate much more than HVHP for that reason.

Interesting test, and a great way to capture the data for display.

Many folks used .32-20 for deer hunting years ago because they "didn't know
any better" and neither did the deer, kept falling over - as long as the shot
was well placed. The cast shows why this works - quite a lot bigger cavity
than the boolit diameter.

That's what I keep saying to folk about the 'Wobbly Bottom Syndrome' with the Cruise Missile 6.5mm bullet. It might wobbly but the recipient was none the wiser.
