Do broadheads shoot different than field points?
The steering effect of the broadheads causes the arrows to be delivered differently than arrows with field points. The orientation of the blades with respect to how the arrow is being delivered determines how much air the blades will catch.
What does a heavier broadhead do?
A heavier arrow with a high FOC has a lower KE but more momentum and thus deeper penetration. The benefit of a heavier broadhead and of a higher FOC is that it is more effective in turning high KE into high momentum.
How does broadhead weight affect spine?
Adding point weight makes the spine weaker. Adding weight on the nock or fletching end makes the spine stiffer.
Why do my broadheads shoot higher than field points?
If the field tips group higher than the broadhead, your arrow rest is too low, which causes broadheads to plane lower than field tips. Slightly raise the rest, and shoot another group. Likewise, for lateral adjustments adjust the rest in the direction your field tips hit.
Are broadheads more accurate than field points?
Yes, broadheads are more difficult to shoot accurately than field points, but making broadheads shoot well doesn’t require a Ph. D. or years of experience as a bowsmith.
How heavy of a broadhead should I shoot?
For big game hunting, find an arrow with between 8.5 and 10.5 grains per inch with a minimum of a 400 spine. This will give your broadhead more than enough weight pushing it to drive it deep into your target.
How much does 100 grain broadhead weigh?
So says the conversion chart on my RCBS powder scale… So a 100 grain broadhead is just over a 1/4 oz? Is grams to grains easier? There are 7000 grains in 1 lb, so you divide 7000 by 16 and get 437.5 grains per oz.
How much does point weight affect spine?
There are many different weight screw-in and glue-on points. Adding weight up front can significantly change the dynamic spine of the arrow. For every 25 grains of weight added to the front, it weakens the dynamic spine by approximately 2 ½ lbs.
What is a good arrow weight for whitetail?
I think a good average hunting arrow should fall in the 6 to 8 grains per pound of bow weight, with lighter bows maybe even closer to 9 to 10 grains per pound. A typical 60-lb. bow should be in the 360- to 480-grain range, a 70-lb. bow in the 420- to 560-grain range.
