Here's the weight of my ICS 400s

29" Shaft 252 gr.
8/32 RPS insert 21 gr.
Easton Super Nock 13 gr.
Field point or broadhead 100 gr.
(3) 4" flectch 14.7 gr.
Total 400.7 gr.

At 250 fps, that's about 55 ft/lbs of Kenetic energy.

The ICS 400s are 8.70 grains per inch, which is borderline. The camo hunters from Beman a little heavier.
