I honestly would not worry a bit about the 204 being a barrel burner like the 22-250. even though the 204 is pushing higher velocities, velocity really doesnt have asmuch to do with burning up a barrel as does chamber pressures and throat errosion. the 204 runs at or slightly above 223 chamber pressure and the average chamber pressure of a 22-250 is a good 5,000 psi higher. asfar as barrel life is concerned the 204 should be compared to a .223 rather than a 22-250.
