IBO Consistency?
During this past week, I picked up a Hoyt Pro Tec (slightly used) from a friend of mine. It was set a 60 lbs. (max) and I turned it down to about 56. Shooting 405 gr. A/C arrows at my draw length of 29", I chronographed several arrows at 256 fps. Pretty happy here. KE is about 60 ft. pounds.
Last Saturday, I did a bunch of chronographing with my son's new Fred Bear Element. With a 350 grain arrow, same draw length,and the draw weight maxed out at 60 lbs. (59 actual), it developed 257 fps. The IBO is 302 on this bow.
Not sure what the IBO is on the Hoyt - but I don't think it's much higher than the Fred Bear - the new "38" version of this bow is something like 310. Something isn't right here. The Element should be considerably faster - with 3 lbs. heavier draw and a 60 gr. lighter arrow - or the Hoyt should be maybe 30 fps slower. Could the Hoyt Pro Tec have an IBO as high as 332? Or is IBO sort of like advertised horsepower? Thx. Roskoe
