Hydrostatically Stabilized Boolits

[Dannix]

I came across this when looking at the heavy .30 cal bullet options at MidwayUSA: Woodleigh Hydrostatically Stabilized Solid Bullets (http://www.midwayusa.com/viewProduct/?productNumber=912713)

Woodleigh Hydrostatically Stabilized 30cal, 180grn

The linked pdf on the product page: hydrostatic_stabilization.pdf (http://media.midwayusa.com/midwayusa/staticpages/pdf/Chart_PDFs/hydrostatic_stabilization.pdf)


I've always wonder how good terminal performance could be achieved with a non-expanding boolit at velocities beyond with FN is effective. Perhaps this is the answer?

Seems to be the same concept as a hard cast wide flat nose boolit.

Take a look at the pdf. It's a reverse-tapered cup-point.

I did look at the PDF.

It appears they may have modified the flat point to a certain degree, but after reading the PDF it appears that they may have taken the way a flat point works, and modified it in a way that allows the same results to be had at higher velocity.

Of course, I have no idea whether it works or not. The terminal ballistics behind it are solid, so one can only buy a few and test them in a proper media.

This new design has been in the field for a while now. In one of the "Ozzie' fprums it's been shown as very effective on buffalo.

I hope it works.

Here is release data on small calibers followed by links to thier use on a buff cull hunt.

Here is a report of thier use on a buff cull hunt in Australia.

A bit more on results.

AkMike, could you print that to a pdf for us? If not, no worries.


Von Gruff, that first link yields an access denied error message.


Here's another related thread from the nitroexpress forum:

I'm not entirely sold on non-lead solids, but that nose design sure is intriguing.

Actually my link is a wartered down version of the posts at Nitroexpress.com that Von Gruff shows.

I saw and held some .375 cal the other evening at the club. Nasty looking bit of work.

Between the nose and the OD of the bullet there is a curve, think of a spoiler
on the back of a race car shoving the air out of the way.
I'm thinking modification of a WFN mold to include that curve,
if it's loaded fast enough would it cause "hydrostatic stabilization"?
Wonder how important the cup point would be, or if it would mushroom and ruin the curved edge.
Might need to be cast hard for this effect.

Just looked again, it's more of an angle than a curve I guess.
