Home Forums Hunting & Shooting General Big Game "The 30-06 is obsolete!"

Let's add case geometry to this. And no, I do not understand it myself.

I note when looking at Noslers data that the improved 30-06 has a .2 gain in case capacity over the standard. That's looking at 175-180 grain data. The charges of H4831 and R22 are the same, yet the velocity is higher with the IMP.

I don't get that.

I did read one article in which the man, who claimed to be an engineer, said it had to do with the reflective angle of the neck wall and the apex of that reflection. He made a convincing argument for his hypothesis, but I don't know if I buy it.
