Gt500 is driving me nuts!!!!

[sr77]

So I have been trying to get this bow dialed in for broadheads. Had it shooting perfect bullet holes at 5 ft. Stepped back to around 25 feet and nock high and left. I am shooting a thumb release consistantly, don't think that is the problem. When I eye the arrow up it seems if I lower the nocking point anymore than I will be below 90 degrees. Love this bow, but man it is tough to tune. BTW, was told by Denny at Elite that this is an 09. Shooting a G5 Expert II., center shot 7/8, 67 lbs. 28.5 in draw length, shooting Maxima 350's. 405 grains. HEEEELLLPPPPP!

I just posted a thread with a very simlilar situation, if I were you I would just walk back tune the bow with your broadheads and field points. I gave up with the paper as did a couple other people here.

Your arrow's are most likely under spined. The arrow charts are wrong for this bow. The cam puts out more "horse power" than the arrow charts allow for. You need a 300 spined arrow when shooting broadheads. Trust me... been there and found out. An easy test is to turn down the limb bolts and shoot some arrows. You will see them start to group.

I was thinking that, but there are a lot of guys that have tuned these bows at this draw weight with these exact arrows. In fact, one poster preferred this exact shaft as he felt it tuned perfectly with this bow, atleast that is what I have read on some of these threads.

Sr77... I've owned a few of these GT500 and when broadhead tuning I usually use a Maxima arrow when doing this and a SLick Trick 4 blade broadhead... Not ALL broadheads group same POI as the fieldtips... SOme have issus with plaining and such and arent as good... Best fit are the Slick Trick 100's with a 350 grn Maxima arrow... Try them,, you'll be surprised... But do walk back type tuning when grouping these... Paper tuning a broadhead is rather silly IMHO...

Does it bh tune for you??

I gave up on paper tuning years ago. But Im not hunting out west or taking long shots. Can't remember my last deer I shot outside of 15yds. Took 1 buck at 30yds but that was years ago. I smell betta now :)

Does it bh tune for you??
Yes no trouble at all. 29 1/4" CT cheetah 300's,Slick T 100 mags,H3ll razors are a bit low say 1" at 40yrds, but dead on right to left.
29' 70# GT.

I like to start with Paper tune. But its just a starting place for my hunting set up.
I shoot both and adjust to tighten the groups between the FPs and BHs.
This is a chart that will help. It tells you how to adjust the rest. Remember to re-sight in the fps then check the Bhs in between. Its time consuming but works..

my gt500 was the same way [hard to tune a bit], dont think I'm crazy, but, after a few eve's in the back yard adjusting arrow flight with the lumenock, I noticed that I wasnt using a stop on the cable slide like I have with all my other bows....put one on along with a simms teflon slide and BINGO...its all good now. Shot my reapers today out to 60+ and DEAD NUTS ON with my field points. Just my 2 cents.

When I got my GT500 to paper tune perfect bullet holes it would not broadhead tune. About 4" was the best I could get with Slick Tricks, Strikers, Magnus Stingers, and Rocky Mtn TI 100's.

When I would get it to broadhead tune I would have a right tear through paper. I gave up on paper with this bow. It did favor a weaker spine and less FOC. It would not shoot my 27" Maximum Hunters 250's but shot the regular Maximum 250's at 27 1/2" pretty good.

My GT500 was just plain finicky but a real nice bow when you got past all the headaces.

I went out today and did some ever so slight adjustments with nock point, for some reason, I hit it spot on. shot great bullet holes and then I did some BH tuning. Split one arrow with a broadhead and shaved the fletchings on 2 others. BH and FP are impacting the same. thanks guys

Just saw this, u should've pm'd me, real busy getting peoples stuff set for the opener here on saturday.

I always papertune at 6', then at 20yards. Both with field points. Then go out and shoot BH's. With compact BH's and expandables this is usually enough. If not you may simply have a BH that planes a bit, spine too weak or not enough fletching.
Walkback is a better method imo but more tedious. I don't usually go to it unless the above fails.


Glad to see you got it working regardless.
