Quote from the above website.

The Swede can be a slow killer at ranges beyond 200 yards. Conventional projectiles, regardless of SD, often fail to produce deep penetration. The 6.5x55 is simply not in the same class as the .270 which it is often compared to, regardless of hype.
Without regard to SD? Duh?

This is so much BS it hardly deserves comment. One of the hall marks of the 6.5 is deep penetration.However let's look at some numbers. A modern chambered Swede with a 140g bullet with a BC of .619 (there aren't any 270 140g bullets with a BC that high) launched at 2800fps arrives at 500yds with a velocity of 2095fps and an energy level of 1365ftlbs. A 270 with a 140g with a BC of .495 launched at 2900fps arrives at 500 yards with a velocity of 2026 and an energy level of 1276. Both rifles fired with equal length barrels. Why would the 270 be a "fast killer" past 200 and the Swede a "slow killer" past 200? Actual performance ain't hype!
