A modern rifle yes. I'm sure you guys would think twice before putting modern 30-06 through a M1903, or modern shotshells through a damascus barrel shotgun.
Either way, i measured the load inside the rounds - 49.5 grains of what i can only speculate is RL-22. If this is the case then my reloading book indicates a max load of 48 grains, but there's probably a fair margin of safety built in. The test gun for the load data was a Swedish M96 after all
