I am a newbie trying to learn fast. My hunting arrows and practice (field tip) arrows fly the same with no kick or wobble. But I have been doing some reading up on GPP so I did the math and I am only at around 7.5 to 7.6 GPP in the bow i plan to hunt with. I believe I will be ok on penetration if I am lucky enough to get a shot and connect with a deer (have a lot of bear around to), but am I damaging my bow slowly by not shooting a heavier arrow? I don't want to make any changes now as hunting season is less than 2 weeks away, but I do intend on installing some 100 grain inserts after hunting season is over. Just looking for some facts,opinions, and suggestions from the pro's at TradGang!
That's on the light side. Some bowyers won't warrant their bows for less than 8 gpp. I would think your bow(s) would be on the noisy side due to light arrow weight. Why wait to try a heavier insert? The increased weight won't affect drop much out to 20 yards. Even adding 100 grains, you'll still be shooting a fairly light arrow.
7.5 gpp puts you under 400 gns-right? As Orion says that is light and raises warranty questions-as well as noise which is especially bad for deer hunting.
You can add the inserts and add a bit of material to your side plate to accommodate the change in dynamic spine. A matchstick under the leather will work just fine-or shorten your shafts. Don't forget the pics!
You might try putting a length of 1/4" poly rope in one shaft and see how it flies with your broadheads.I'm not normally a fan of internal weights but it shouldn't change flight a lot and may work plus,if it doesn't,easy to remove.
For sure,if you add a 100 gr insert,it will change everything and you may not have enough stiffness in that 3555 to make it work.Next year you might try either a heavier shaft or a 5575 with more wight on the front and....start a little earlier figuring all that out.Good luck with it.
If my math is right my arrows (tipped) weigh 421 grains not counting the wrap or feathers.
Gold Tip Expidition Hunters: 8.2 gpi (30") = 246 grs
Nock and Insert at 11.5 grains each = 25 grs
field tip or broadhead 150 grains = 150 gr
Total = 421 gr
This may be all wrong??
Also plan to hunt with the Coup stick that is in my signature and I draw around 27.25". Haven't checked in a while
ttt
419 is what i got you didnt add the nock and insert right should be 23 not 25 and you can add 12 to 15 grains for feathers...i got lucky i shoot axis full metal jackets 400s and a 29 inch arrow with 220 up front i got 560 grains and i shoot a 56 lb.bow....
i would want something a bit heavier, but your setup will definately kill a deer if you make a good shot and don't hit solid bone. I personally would be worried about the low Gpp on you bows over 50#
If your arrows are properly tuned and you swap standard inserts for ones weighing 100 grains, your arrows will no longer be tuned. I would never sacrifice proper tuning just to add 80 grains of arrow weight. A light arrow that flies straight will penetrate much better than a heavy corkscrew.
