The FN solid and SP VLD designs are good to go, but the hollow point expanding HV prototype needs a test of expansion.

It is hoped that at 2600 fps impact velocity the petals will blow off and assure an expansive wound followed by deep penetration of the residual "wadcutter."

To be tested at 1500 fps to 2500 fps impact velocity for fine tuning the HV prototype design: water is a severe test of any expanding bullet.

Resistance in water increases in direct proportion to the square of velocity, like a visco-elastic tissue. It does not take much water to stop an expanding soft point.

Rip shall ride the Iron Buffalo again, with water bags and cardboard witness partitions between the bags. No plywood boards.

We already know everything necessary about solid penetration: Use an FN.

Now where is that picture of crazy bro' Ted Nugent riding a bison?

Bareback or saddle?

The Iron Buffalo will be saddled up again.

RIDES AGAIN!

This time as the "Water Bison":



A .395 Tatanka shooting 340-grain HV's, into water bags lined up 8.5 feet deep, impacting at velocities in the spectrum of 1500 fps to 2800 fps: That ought to tell something about the expansion characteristics of a GSC HV.

Pictures of expanded bullets and chronograph data to follow ...

Challenge to Gerard Schultz:

Design a nose cavity for the .395/340-grain GSC HV that will open up in water at 1500 fps, retain expanded petals through 2500 fps impact in water, and blow them off at 2600 fps impact, turning the bullet into a solid that will exit the other end of 8 feet of water bags, into a 6" thick stack of plywood at the other end, for recovery.

Is it possible?

12" twist at 1500 fps to 2800 fps. Never forget the T-word.

how about mixing up some balistic gelatin and place blocks of that between boards? no splash but a good medium for testing...better than wet phone books.

boomie,
Have you ever had to prepare, calibrate, refrigerate, and transport "tons" of ordnance gelatin?

Do you know how quickly that stuff starts stinking to high heaven in the heat?

Water is a good test of a soft point to be used on game, if all you are looking for is expansion versus impact velocity.

I think Gerard has good experience with correlating the "water torture" test of his HV's to how they perform on live game.

He will know what to make of the results, even if I don't.

you could make extra strong cherry jello

8 packs per gallon should do.

afterwards whatever does not hit the ground you could top with whiped cream for a nice treat

plus i want to see what jello at 2700 fps looks like

Having "served" at a test facility where ordnance gelatin was used extensively, I'll go along with the water test. If Gerard can come up with a bullet that meets RIP's criteria for velocity range and retaining the petals, it would have to be an outstanding bullet for both sides of the atlantic.

If Gerard's first prototype makes the .395/340gr HV open up at 1500 fps yet hang onto its petals at 2500 fps in water ... then Gerard walks on water.
