My Vulcan shoots a 393 gr. ICS Hunter 66#/29" 284 fps. Thats with rubber tubing on peep, rubber string silencers and d-loop.Very quiet though..On 70# it shot 297 same arrow.

Just a comment about the Vulcan vs Gaurdian, some bows are less efficient and loose more speed per grain of arrow weight. So even though the Vulcan shot the 450 grain arrow faster than the Guardian, they still could have nearly identical IBO speeds.

I agree with you there, passthru79. Maybe you can help me with this as I have been wondering this about several bows.

Bowtech claims that the Guardian is their most efficient bow with (correct me if my numbers are right) 87% energy transfer. Is it possible that this is only at the IBO speed and that this level of efficiency can be deminished as you add more weight to the arrow that you are trying to transfer the bows energy to? And if this does happen, what should you look for in a bow or the bow design that would tell you how efficient the bow would shoot at 50 grains, 100 grains, 150 grains over IBO?

Just trying to figure out how the bow loses, at least to some degree,it'sability to transfer energy to the arrow just based on how heavy the arrow is. Please realize that I am not contradicting your statement, but rather trying to understand everything I can about bow mechanics and what makes different designs perform the way they do.

Knowledge is power....lol

Actually the bow should be more efficient at transferring energy to a heavier arrow than a light one. That 87% efficiency rating might have been done for a log that the bow only threw 10 feet, the "truth" is in the details...
