Default RE: Carbon Revolution Black Diamond Arrows=30-150 fps Faster???

Frank, I just wandered around t the AMO chart and you definitely have a point. Most people definitely ARE shooting well under the AMO chart.

Looking at my stuff, I'm okay. At least NOW I am. For my round wheel ProTec @ 60 pounds and 33" draw, it shows a minimum arrow weight of 352 grains. 5.87 grains per pound. All my ICS type carbons weigh around 450 grains with feather fletch and 125 gn tips, so I never even got close to minimun with this bow.

For a 70 pound, hard cam bow at 33", it shows a minimum of 586 grains or 8.37 grains per pound which would have me shooting at least 2419's. When I was shooting those carbons on my hard cam 70 pounders, I was 136 grains UNDER AMO minimum! No wonder those bows rattled and clanked so bad when I got rid of them.

Now, someone with a more normal draw length, say 30" and shooting a 70 pound hard cam bow, the recommended minimum is 487 grains, a fraction of a hair under 7 grains per pound.

So most are already well under the AMO minimum, but is that really a reason to use even lighter arrows?

And I guess that forces me to retract my earlier comment and change it to anyone not shooting a minimum of IBO legal equipment needs to stay away from our club.
