HYDROSTATICALLY STABILISED BULLETS

​

Woodleigh Bullets has been built on evolving and changing and, to meet this demand, Woodleigh have begun marketing a range of Hydrostatically Stabilised bullets.

 

Hydrostatic stabilization is a technique that has been used in the brass extrusion industry for many years. It is a method of producing pierced hollow bars to very precise concentricity by using tool design to harness hydrostatic forces to centralise mandrels when punching through brass billets.

 

Woodleigh Hydrostatically Stabilised Bullet -  For the first time this concept has been used in bullet design to harness the same forces to produce a bullet that resists deflection and achieves deep straight-line penetration.

 

The task was to design a bullet that would bridge the gap between traditional expanding bullets and modern solids. These new generation hydrostatically stabilized bullets deliver tremendous shock transfer with deep penetration and extremely reliable straight line performance.

​

The depressed nose at the leading edge of the bullet 'cores' the medium (flesh) through which it is travelling which then creates a 'pressure ring'. The coring and pressure ring balance each other out to stabilise the bullet in the direction of travel. If the bullet hits hard bone the flesh core dissipates but immediately reforms and the balance between it and the pressure ring restabilises to redirect the bullet in the original direction of travel.

Additional benefits of this design are that the pressure ring creates a devastating wound channel and massive hydraulic shock transfer. The bullet actually travels in a low pressure cavitation bubble which aids in bullet stabilisation and greatly increases penetration due to significant reductions in frictional forces acting on the bullet (ref Fig).
