6.5 Creedmoor-> 54.0 gr. H2O
6.5 Swede-> 57.9 gr. H2O
6.5 PRC-> 68.8 gr. H2O
Seems the 6.5 Swede falls nearly halfway between the 6.5 Cm and 6.5 PRC and IF loaded to modern standards in a modern 6.5 x 55 rifle that will stand higher pressures the Swede should be decent on most bug game in North America. After all Europeans have been using it successfully for many, many decades on the slightly smaller European moose ("elg").
But my interest, since I have a 6.5 PRC X-Bolt, was to see just how much more case capacity the 6.5 PRC had. It is eye-opening that it has almost 10 more grains of H2O capacity than the 6.5 Swede. Enough to handle American bull elk at say, 300 yards max.
And then going way up to the soon-to-be-released 6.5 RPM Weatherby at 82.5 grains of H2O you get a clear idea of how powerful it is.
Of course the 6.5 /28 Nosler has to be screaming with 100.8 grains of H2O. (Yeah the 6.5-300 Weatherby is barely above it in case capacity and is for all purposes its equal.
I think case capacity tells a lot about comparative power in equal bullet caliber & weights.
