I posted this previously for 2 3/4" and 3".

"Here's what I just received from Kent - Game Bore.

12 gauge bismuth 2 3/4", 1 1/16 ounce=9800psi, 1 1/4 ounce=10,000psi

12 gauge tungsten 2 3/4", 1 3/8 ounce=11400 psi, 1 1/4 ounce=9900psi,

12 gauge tungsten 3" are at 10,400psi and 11,300 psi"

Just send them an email and I suspect you will get the pressure data for the 2.5". And then let us know what it is.
