The fastest round of the above mentioned is the is .220 swift if the .204 is shooting a 40 grain bullet. If the .204 is shooting a 32 grain then it tops it by a mere 50fps. This ishornaday factory loads not hand loads. Over the last 70 years the swift has been the most compared to round out there when talking about varmit hunting. I have read about but never have tried to make my swift go above that velocity.My hand loads shoot the best around 4150fps from my ruger. The .223 wssm will top the swift when hand loaded and I am sure there are plenty more wildcat cart. out there.Most of the time speed is not most important factor in shooting.
