A new bullet design
Anybody heard of these? Woodleigh Hydrostaticly Stabilized Bullets.

They start talking about them just after the 4 minute mark on the video.

Wow - very interesting! No T-Rex in my neighborhood, but quite a concept. Thanks, Rusty.
As for the Star Trek shotgun round, entertaining - thanks, Ironsights!

Ok, I have no personal knowledge, but it seems Vince Lupo, and Randy Garrett solved this problem a long time ago in 45-70. Garrett's best .44 mag Hammerheads seem to be able to travel the length of a grizz.

Re: A new bullet design
Take a close look -
These new bullets are scooped on the shoulder, and dished on the meplat, which apparently creates a pressure wave around the projectile for that larger wound channel.

actually Blaine, you witnessed this:BlaineG wrote:Ok, I have no personal knowledge, but it seems Vince Lupo, and Randy Garrett solved this problem a long time ago in 45-70. Garrett's best .44 mag Hammerheads seem to be able to travel the length of a grizz.
if you've seen the video of the 525gr piledriver penetrating a dozen one gallon jugs of water, you could see the plank levitate off of the supports due to the hydrostatic shock, and the bullet drilled straight thru the jugs without deflection. we take this to indicate that the bullet is hydrostatically stabilized, and the shock value to the flesh is ginormous.
in the video at 11m42s is the EXACT SAME explanation of the LBT or truncatec cone performance. same gas envelope and same "stabilized" bullet path v.s. round nose bullets.

Re: A new bullet design
there are a bunch of images showing the same effect with truncated cone flat nose designs, with some applications to torpedos. I don't have current links, but probably ten or so years ago there was lots of talk talk about this and lots of pictures. including, I might be remembering, images of a russian projectile of some sort with the same idea of a 'vaccuum envelope' that reduces resistance, and increases the tendency of the projectile to go straight.JohndeFresno wrote:Take a close look -

If I had a lathe, I have a hammer but not the skill set to make perfect cylinders with it, I would turn some brass with Marshall's nose profile and do the gel test. My guess is exactly the same results, or better, as the scooped shoulder-dish combo.
I might also suddenly be remembering a S.Africa concern doing this exact thing with brass or copper. Anyone recollect this?

Chris Massaro was a guest on the reloading podcast recently and he talked about these. He said he took a body shot on an elephant that went 16 yards before it dropped. The round totally scrambled the insides and passed on thru. All the way, in and out.
Oh, the round he used was a .404 Jeffery.

Re: A new bullet design
All them designed are based on utilizing cavitation to create a 'bubble' around the projectile when passing through fluids. In the 1920's the navies of US, GB, Japan all experimented with flat nose bullets having large meplats to produce cavitation with the intend of using them to penetrate below waterline armor of warships. More recently the US and others have used flat tipped bullets in small cannon to permit the detonation of submerged naval mines. Not only does the cavitation reduce drag it reduces yawing as the project travels through a fluid. It also turns out that flat tips enhance above water penetration of armor plate where the plate is <150% of projectile diameter. AS far back as the 1880's it was known that blunt/flat AP shot was less subject to deflection and ricocheting.

Re: A new bullet design
Thanks for that info. Pretty much how I recalled it too. Old school is cool and old old school is more cooler.
