Post the carton end flaps, if you can. As a W.A.G., probably late 60's to mid 70's. The "Surefire" mark in the "X" is throwing me a bit, and may be a modern retro styling.

ETA: It's probably fairly modern. I mistook the X marking for Surefire when it was simply "Super".

I found the older 70's-80's Super X hollow-points to be fairly accurate and consistent. The latest, modern batch has been throwing a few fliers for me lately, which hints at manufacture changes.

Regards,
