Hey, someone had to have the 250ith post to this subject
TFOX, I think we are agreeing to an extent. I am only saying that basically, all else beign equal (shaft diameter, fletching, head etc) the heavy arrow keeps it's speed longer.
The skinny carbons will have a lower cg and that will make up for last of momentum vs the wind.
"The archery program" shows that a 450 grain arrow shot out of a test bow starts at 235 fps and after 100 yards slows to 189fps
The same bow shooting a 350 grain arrow starts at 267 and drops to 202
The light arrow is doing 220 at 70 yards, the heavy one 220 at 30 yards. Starting with both arrows at the same speed (220) the heavy one slows to 180 fps in 90 yards the light one slows to 180 in 70 yards. At 30 yards, the lighter arrows will hit about 2" higher.
I think we can agree that ALL else being the same the lighter arrow slowes faster....if we want, I'll check the results of same weight but different shaft size arrows (and or feathers vs. vanes)
