Whenever I turn to the Big Bore section of this forum, it's in hopes of an interesting read and exchange on some really fascinating bore above .40 that's lately been resurrected!
However, I must admit that the 9.3 X 62mm is fascination enough!
I have to go to a meeting just now, but will be back in a couple hours to see how this is developing. In the meanwhile, if you care to, you can read my blog on some of this at
