Hi Gang,

I'm trying to select the correct weight of cedar shafts for my new setup. I am shooting a Browning Wasp 42#@28. My draw length is 27-27.5. I'd like to use a 30-inch shaft if possible, with a 190-200 grain head. I looked at multiple spine selection charts. The general consensus based on the charts was 60-65 spine. However, when I called and spoke with a rep from Three Rivers, his recommendation was 50-55. He also advised that their company spine chart was on the heavier side. I am torn on this. Any advice or recommendations to break the stalemate would be appreciated.

Best,

Ed

Because a 30" shaft is ten pounds spine weaker than a 28" one, of which all wood shafts are spined for. And your use of 190-200 grain points weakens it another 10 pounds spine.

Why do you want to use such a long arrow?

What Kelly said. Long arrow, heavy point make the shaft weaker. Part of what I call the "5# rule".

55-60#.  Does Three Rivers still sell bare "try shafts" of three different spines?  Try 50-55, 55-60 and 60-65#.

I agree with Kelly.  If you went to keep your arrows that long and points that heavy, you're going to need the heavier spine.

Im not a gap shooter but a local friend has long arrows that are a specific length so his gap distance works,, maybe thats why the longer arrows but im just guessing,,,, if not i agree trim them back.

My setup is 64" Yellowstone Longbow 42@27.5 and my arrows are 29" 45/50 and my point weight is 145 gr and that a little stiff out of my bow but that the way I like it, I uses the same arrow with my 47@27'5 bow I wouldn't go with the 60/65

Blake.  Though your bow's about the same weight at about the same draw length, it's probably cut proud of center whereas the Browning is likely cut to center.  Your arrows are an inch shorter and point weight 50 grains lighter. All of those enable the lighter spine you shoot.

If using the arrow tip to aim, a longer arrow will shorten your point on distance, whereas a shorter arrow will lengthen it.
