I have an odd fascination with obscure, European, and historical sporting rifle cartridges. I should have guessed the 5,6x57 since it looks the same length as the 7x57, and I thought the 9.3x62 looked a little "odd" but yes, the .454 was a mean one! Thanks for the challenge. :-)
as a side story, I was just offered the chance to buy a Brno ZKK 600 in 9.3x64, that's a very nice cartridge and rifle combination but I passed up the opportunity. So many cool cartridges and rifles to try, too little time and money!
