If, tungsten weighs twice as much as lead do you have to use half as much?

Yes. Half as much volume but not weight. The 1 1/4 ounce number 9s that I killed turkeys with in 12 gauge is a very small amount of shot. That's why in the 20 gauge with one ounce there is the top of a 28 gauge wad inside the 20 gauge wad and also a filler wad.

Because the shot is so much smaller, it is not affected by the drag of the wind and retains so much more energy down range. Being small, it meets less resistance once it enters the game, thus having shot that will penetrate all the way through the animal.

Jerry, much of what's been passed here is in subjective terms (less wind drag, more energy, less resistance, complete penetration through the animal?).

It would be good to see the inventor's tech data that compares velocity and energy bleedoff rates for tungsten vs. lead with the same diameter pellets at 10 yards or so increments, something like 20-30-40-50-60 yards. Also to see the measured penetration at those yardages in an accepted medium like pine wood or similar. Data for lead pellets is available from references. Downrange pattern density is one parameter, but measured terminal velocity, energy and penetration are other important ones for the inventor's different pellet sizes and especially so when recommending something like TSS 9's for turkeys at longish ranges.

"The Tungsten 9s have the same penetration at 70 yards as lead 9s do at 15 yards" ….. I'd particularly like to see the tech data on that.

Frank,

I posted it earlier in the thread.
