Tip: Keep one depth check point every 6 feet so your average depth stays accurate across sloped pads.

Tip: If delivery trucks dump loosely, use the higher end of the weight range before planning trailer loads or split trips.

The shape are made up of all different parts that forms complete arrow. Here the insert, the point and the fletchings. You can add weight at the nock end, at the point end or according to the whole length.

Exist several ways to do that, for instance by means of weight tubes, brass inserts or nock adapters.

How to Choose the Right Arrow Weight

One calls GPP the whole weight of arrow. Lightweight arrow has GPP of 5 until 6.5 grains for every pound of draw weight. Good rule of thumb say, that arrow must weigh at least 5 grains for every pound of draw weight.

For instance, 50lb bow requires 500 grains, so 10 times 50 grains. Warbow with 100 pound draw requires arrow of 1000 grains. 65lb draw gives outright 390 grains, if you uses 6 grains per pound.

Arrows of 500 until 600 grains and more break bones and penetrate deeply. But they seriously fall after 40 yards. For the most hunters with arch, arrows of 450 until 500 grains are the best.

Some use 800 grains at 60lb bow for more momentum and penetration, but everything depends of that what you fits to shoot. Too lightweight arrow expands the noise of bow and the shock in hand. Very lightweight arrows can even damage the arch as if dry fire.

Lightweight arrows fly more quickly and more far than heavy arrows with same draw weight. Generally heavy arrows go more slowly. It Is possible to shoot the heaviest arrow that yet reaches 270-280 fps.

If arrow flies in 300 fps, you can add weight for slow it. Kinetic energy measures the energy of object in move. It matches arrow weight multiplied by means of square of arrow speed, divided by 450,800.

Arrow weight do not match arrow spine. Spine relates to the stiffness of arrow. Weight does not decide as far as bends the shaft from the bow.

The weight of the arrowhead also alter the parabolic action of arrow what can expand or reduce the flexiblen during flight.
