I would like to try shooting a heavier arrow without changing tip weight, and the easiest/cheapest/simplest way for me to do that would be to get arrows that have a stiffer spine. (I'm due for some new shafts anyway) If I go up a notch on the chart, to a stiffer arrow with a heavier GPI number, would I be tuning myself into a corner? Is it possible to be "overspined"?

To answer the question though, first we need your current spine, head weight, arrow length and bow weight....as well as the type of bow. Have you considered adding weight via inserts? I am not a big fan of simply slipping a tube into a shaft but if it is made into a permanent part of the arrows structure...that will work and be cheap. |

You could fill your current arrow with fine grained salt, it de-spines the arrow a bit, but does add weight. Also, the salt will pack in after a few shots, too, and you'll have to add a bit more to keep the "cargo from shifting at the release. A pal of mine went to Africa, he filled his shafts with fine salt and then shot them in, refilling as required. Going to a heavier arrow with a stiffer spine might work for you. I can shoot GT 7595 or GT Big Game 100+ out of my bow at 70 pounds just fine. The 100+ is a stiffer spine. I think that the center shot of the bow and the use of a release really help one get a stiffer arrow off the rest.
By the way, that much salt makes a much heavier arrow.

I am shooting a PSE Beast @72lbs., 27.5" DL. Arrows are currently Gold Tip Expedition hunters, 55/75, black, cut at 25 3/4" (slightly over 1 inch in front of rest) with 100 grain tips and 3 4" Quickspins with Monokote wraps . I use a drop away rest and release. Those arrows are 8.2 gpi. I'm thinking of going to 75/95 in camo at 10.2 gpi, or 75/95 Traditionals @ 11.0 gpi. I'm also planning on cutting these new arrows at 26-26 1/4 inches and not using wraps.

They're cut to 26.25". With 100grain tips, they'll weigh in about 505grains. They are fletched with 5" feathers. If they don't work, no biggie, just pass them along. If they do fit the bill for you, I can give a heck of a deal on some FMJ's that are still new in the box. |

Hey, I ain't using them. Those new FMJ's just came to my door yesterday.  Besides, if I sell the arrows all proceeds go to a good cause: The Robinson Bowhunting Fund.  |

That would be a very cool thing...that's upper end of the weight I'm looking to be at! I weighed all my arrows today, and they average 380 grains, with a difference of 2.8 grains from the heaviest to the lightest. (I'm pretty proud of myself, I just started building my own arrows last year and didn't expect to be so consistent over 18 arrows, built at different times!) I want to be at least 100 grains heavier I think. |
