If you’ve kept up with my non-sense in the ‘one-shot everyone knows the rules’ thread, you’ll know I that I got a new #55 bow that I was hoping to using existing pre-cut 300 spine arrows with. Do to the ‘to-center’ cut of the riser, the 300 spine, 650 gr TAW arrows were still over-spined for for my draw length of 28-29”.
I had two 340 spine arrows that I was able to try out and confirm that they flew close to perfect out of the #55 bow with the same 100gr insert and 200gr broadhead I already had available and wanted to use. So I went ahead and bought the new 340 spine arrows, but after about 3-4 weeks worth of trouble with UPS the seller refunded me for the arrows. If I go this route I’ll be shooting 650/55 or 11.8 GPP.
During this waiting period I tried several weight combinations with my old 300 spine arrows to get them to fly well and finally came to 740 grains TAW. That puts me at 740gr/#55 or 13.45 GPP (grain per pound). The arrows are a little quiter, they stick into the target a few more inches, and they are noticeably slower. Now I have to decide if I want to set up my 300 spine arrows for this weight, or still buy new 340 spine arrows and set them up for the 650gr which I know also flys well.
Finally I will say that both arrows (650 and 740) shoot very well and the drop off to 20 yards (my max range) is negligible or barely noticeable. Speed and penetration seems to be the thing I notice the most between the two arrow builds.
Please let me know what you think I should do if I was you. And…
