John Linebaugh and others say that the "typical" pressure signs don't always show up on straight walled large bore cases. He's personally fired .45 Colts over 50,000 cup and not had flattened or cratered primers. I should E-mail him, but I'd bet he's pretty busy. As I'm about to start loading for my Casull, I'd like to know how these large calibers express overpressure charges, since they might not display is by regular means. The Casull uses small rifle primers for more case strength, and that would leave less srea for pressure to affect the primer. Hmm...
