the 8x60mm round is no slouch in the ballistics department either.
It may be annoying to an Anglophile, but the 8x60S, the old "Versailles treaty cartridge", is fully the equal of the venerated British .318 Rimless NE, comparing ballistics.
Kynoch now lists these muzzle velocities for their .318 loads, taken with a 28" test barrel:
180 gr bullet at 2700 fps
250 gr bullet at 2400 fps
Instrumental velocities, 5 m from the muzzle, of my 8x60S loads, from the 22" barrel of my Mannlicher-Schoenauer M1925:
180 gr Barnes TSX bullet,52 gr VV N140 at 2720 fps
250 gr Woodleigh bullet, 53 gr VV N160 at 2330 fps
Granted, the .318 bullet is larger by a mere .006". But I doubt any animal or hunter will note a difference in practical use.
The 8mm is slightly superior in at least one respect: The 8mm 250 gr bullet has a SD = .342; the .318 WR 250 gr bullet has a SD = .328. So theoretically, the 8mm bullet should penetrate a little better at the same velocity.
