Arrow dilemma and possible solution...

[returnofsid]

I shoot a Hoyt Carbon Element 60-70lb. set at 65 lbs. with a 28" draw length.  Arrow length is 28.5" nock valley to end of insert.

My arrows are Gold Tip XT Hunter 7595 340 Spine.  I shoot 100 grain Field Tips and 100 grain 3 blade Muzzy and/or 100 grain Magnus Snuffer SS broadheads.

Here's my dilemma. My girlfriend's father bought me half a dozen arrows, cut, custom wrapped and custom fletched them up.  This was a Father's Day gift.  I made him a PVC bow stand, all painted up in Camo, but that's beside the point...haha.  The problem is, he from Montana and not familiar with our 6 grain/pound of pull weight rule.  He purchased Gold Tip XT Hunter 5575 400 Spine arrows.  They're cut to the proper length but obviously they're a lower spine rating and lighter arrow.  Obviously they hit higher when shooting.

I hate to not be able to use them!  So I've been thinking about options that might allow them to work.  Gold Tip offers a FACT System, in which you can add weights to the back of your insert, inside the arrow shaft.  These weights are available in 10, 20 and 50 grains and can be "stacked" or combined to precisely customize your arrow's weight and FOC.  Would this system work to make the 5575s fly like the 7595s? Would this system increase the spine of the 5575s to near the spine of the 7595s?

I think adding weight to the front if the lighter spines arrows will make them hit lower, but they will not be as accurate as your 340 spines arrows because if the added stress on them that they are not built to handle.

It will decrease the spine , maybe they will work if you shoot 60 lbs. But most likely you have trading stock

Sounds to me like you have a really good reason to by another bow in the correct pound range.  It will kill just as well and you will have a back up bow......
I think you have a crafty potential future father in law that knows how to get you new toys!

Ummm, that'll never fly...haha.  I just purchased my Carbon Element a few months ago.

I'm not sure that the arrows are not built to handle it.  According to GTs arrow selection chart, if I were shooting 60-64lbs, the 5575s is exactly what I'd need. Unfortunately, with Washington's 6 grains/lb of pull rule, the 5575s don't make the weight, unless I shoot a heavier broadhead, longer arrow, or add the FACT System weights.

So, maybe I should drop down 63ish, add weights to the 5575s and then shoot the 5575s and 7595s to see how it goes.  The next question is, if I were to try this, how much weight would I add?  Would I just add enough to get the 5575s to weigh the same as the 7595s?

Wait, decrease spine?  Okay, I definitely do not want a decrease in spine.  Bummer.  Why did I assume that adding weight would actually increase spine?!

[returnofsid]

I guess my only option is to just put these arrows away, holding on to them until either my girlfriend or daughter are shooting 50lbs or more.  Bummer!

Just periodically pic up the arrows and fondle them and mutter if only I have the right bow..............

Adding weight on the front end makes the arrow shaft work harder to propel the arrow forward which means it will cause additional flex.  If anything, adding weight to the front end may cause the need for a stiffer spined arrow.

[coachcw]

Any time you ad weight to the front you decrease spine since the arrow is pushed from the rear causing more flex in the shaft. Wight tube may be an option but the spine is marginal at best any way

[returnofsid]

Well, it's official.  These arrows will sit, ready for the girlfriend or daughter to draw higher poundage.  Then I'll cut them down to their length.

[Come Get Some]

Good choice to let them sit. Adding weight to the front or rear will change your FOC. You will probably have difficulty getting good groups with broadheads

[MtnMuley]

He'll. They're GT's......I'd just get rid of em

Theyll be fine for field points id just use them for 3dthe shoots.  Resight before hunting season.  Lots of guys use lighter arrows for a flatter shot on the course.
