Thread: The 8x60 S

Not all you read about the 8x57 is based on fact - aAmerican gun writers have a lot to answer for. I have a 1920s (probably) Kettner 8x57 barrel fitted to a Brno action, it slugs at .320 and shoots just fine with .323 projectiles (and factory ammo). An 8x51 has a .319 bore and shoots 323s as well, althoughits much more accurate with .320/321s . And I have a std 323 one.

My understanding is that the change in proof laws meant that rifles chambered in 8x57 after WWI had to have a throat that would safely allow them to shoot all projectiles. This the concept that is beyond the understanding of many american writers. Next time I stumble accross an authoritative affirmation of this concept I must properly reference it!

However Quickload (developed and owned by a German) says there are two versions of the 8x60, one at 318 and an "S" bore one at 323.
