I have two T3's in 6.5x55 and a Serengeti in 6.5x284. From my limited experience with those rifles and calibers, the 6.5x284 does not offer much more velocity with hunting length (22-24") barrels and modern actions. The 6.5x284's the competitors use are sporting 30-34" barrels I believe. That's where the bulk of the velocity advantage comes from, it seems to me.

We may know the time Ben Carson lied, but does anyone know the time Hillary Clinton told the truth?

Immersing oneself in progressive lieberalism is no different than bathing in the sewage of Hell.
