RE: .204 Ruger?
Dan, That is some nice shooting there.
Hope one does not mind me dropping an opinion & my reasoning as to why a 22-250 may reach same velocities as a 220 swift while enjoying a longer barrel life.
The 22-250 is smaller a cases with less volume, which may allow this cartridge toattain a respective velocity with less powder than the larger swift cartridge. More powder generates more throat burning heat in the 220 swift than the lesser charge used in the 22-250 chamber. This is only a theory in my mind.
Yet I have little doubt that the theory will hold water.
This is the same reasoning, which I buy into - that the 204 Ruger may reach & perhaps exceed 220 swift velocities and enjoy a longer barrel life.
