Geno, I apologize if my post upset you. It was genuinely intended to keep this discussion "fun" and to encourage both sides to contribute any data or information they're aware of. Perhaps American humor just doesn't translate very well into Russian. Or maybe the Russian culture doesn't understand the "wink" we Americans often use. Anyhow, how about avoiding personalizing your frustration or anger.

Let's clarify the specific point we're debating: suppose I have a gun chambered for 2 1/2" shells and fire a shell of that length that generates 6,500 psi. I then fire a 2 3/4" shell in the same gun that generates exactly the same 6,500 psi peak pressure. What significant difference is there? We would really like to know.

Have a great day! smile
