Actually, I read this in the paper magazine, a very good article.
The 30 Super Carry:
Filling The Power Gap
The 30 Super Carry:
Filling The Power Gap

clik hereThe 30 Super Carry averages around the 1,250 fps mark with a 115-grain defensive bullet — and this load isn’t for the faint of heart as it generates some 50,000 psi of pressure.
A high-performance 9mm load can generate “up to” 35,000 psi at maximum pressure.
Even the cherished .38 Super and .357 Magnum max out at about 36,000 psi for some perspective.
Do I have your attention yet?
