grains per pound
 

Does the minimum of 5 grains per pound mean complete arrow weight (including broadhead, etc) or just bare arrow?

complete arrow weight. You can count on three 4" vanes being around 24gr.Or 35" feathers being half that.Nock about 5-9 grains.

i would check your 5 grains; most manufactures void the warrenty at 6 grains per pound AMO.

Typical Carbon arrow weight, and by that I mean the standard 5/16 O.D. carbon size runs around 8 grain per inch, with components (vanes, nock, and insert) you are probably adding another 40-45 grains, then add your point weight and get a total.

I shoot a 28" carbon at 8.2 gr./in. so thats 229.6 + 42 (nock, insert, blazers), and 100 gr point for a total of 371.6 grains.

With that set up shooting 70lbs I would be at 5.3 grains/lbs, which like Waltwittman says is pushing it a bit, so I added 3 gr/in. weight tubes which, after cutting to fit between insert and nock, add another 81 gr bringing me to a total arrow weight of 452.6 gr.

With that weight at 70lbs I now have 6.4 gr/lbs.I have not compared the speed variance of the arrow with and without the tube, however, I am shooting forpenetration and I sure do like the KE I get with that setup.

If yer gonna hit em do it with aMack truck - not aTonka truck!
