Proper arrow length

[USMC 82-86]

#5997

What is the proper length arrow for my draw length and bow weight? My draw is 28″- 28.5 if I give it a little extra. I keep a slight bend in my bow arm and I cant the bow as well. My bow is 66″ and is 55#@28″ and I am using a Dacron string. The bow is fast flight capable and it is cut about 3/16″ from center. What spine would I need as well? I am looking at POC, Sitka Spruce and Douglas fir as possible choices for wood and I am looking at Traditional only carbons or any suggestions out there concerning the carbons. My plans are to use 125gr points and or broadheads and 5″ shield cut feathers. Please any suggestions. Thanks:idea:

USMC,

Personally, I like to have a couple inches of arrow out in front of my riser. This helps keep the broadhead away from any stray fingers that might be sticking out. Also, before you solidify your plans on your broadhead weight, check out the Ashby Library on weight forward and penetration and broadhead lethality. There is a ton of information in there, and you might change your mind about your choice of 125’s. Good luck.

Michael.

You will want at least a 29″ arrow. At that length, I would recommend a 55-59 lb spine for your bow and point weight. Add another 5 lbs spine for each added inch of arrow length and maybe another 5 if you go up to a 160 gr point.

Fir and sitka both make very good arrows. IMO, fir is the best shooting wood and carries good weight for a hunting arrow. Spruce is quite light and lends itself well to using heavy point weight for high FOC, until you run out of spine at about 75 lbs. Both are much more durable than POC.
