In this case, the density of the bullet is increased so there no loss of sectional density even though it is shorter. SD is just a ratio of weight to diameter. Length isnt part of the equation. I could make an earplug with a SD of .330, but it still wouldnt penetrate very well. Since Tungsten is significantly denser than lead so you can shorten the bullet, maintain the same SD, it will be more stable and rigidize the bullet to the point that it is almost not malleable at all. Tungsten has one of the highest tensile strengths of any metal. Its really the best of both worlds except for the cost and manufacturing difficulty. And the stupid BATFE...Shortening the bullet reduces sd a no no for dg.
Small meplats do not work anither no no for dg.
Large meplat and monometal is the way to go or hollow point such as the hydro simple but effective and gets the job done....
In Theory, yes. In reality, I would think the tungsten core would perform better because it is so much tougher and a shorter bullet is more stable and will stay nose-forward better... though I don't know if it would be significant. What it should do is let you drive the same weight bullet to the same speed at a lower pressure (with relieving bands). Again, theoretically. The tungsten is so hard and incompressible that it may actually make the bullet harder to push down the barrel, although I'm sure the engineering dept. could solve that.so a short bullet vs a longer bullet of the same weight fired at the same velocity will penetrate the same distance in the same mefium??
Speer's did. The tungsten solids they made had the solid tungsten core with enough jacket over it to allow for barrel travel without over compression.In
