Did anybody hear about this caliber? I happen to have XP100 in this caliber. On the barell it reads "HELM 747 THUNDER JET". Looks like 7mmTCU. This wild cat could be made before 7mmTCU? Thanks for any info.

    Last December I asked you about this cartridge I didn't know nothing about ..747 Thunder Jet....
    Thanks to you guys and to your knowledge now I not only know all (almost) about it, but I have dies, brass and loading data for for this cartridge! On top of this I had the privilege to talk to the Inventor himself... Thank you guys again!!
