Hello,

The more and more I read about guy's arrow set ups, it seems as though mine are quite light. I am shooting a Thunderhorn Coup Stick, draws 55# @ 26", but I draw it to about 28", so closer to 58 or 59#. (Going to find out exactly next time I stop by archery shop).

Anyhow, the bow came with a half dozen arrows, that it seems to shoot just fine. They are Gold Tip Traditionals 5575, cut to 29" with 175 grain field points. Total arrow weight is 441 grains. Do you guys think I might benefit by adding some extra weight adapters?? Like I said, these seem to be shooting without a problem. Why so many guys use such heavier arrows??

Hey bud.  You're arrows may be a tad light...but depending on what the bow manufacturer suggests, they may not be too light.  Most bowyers suggest an arrow that weighs at least 9 grains per pound of bow weight.  The lighter the arrow...the more stress on the bow.  If you are pulling 58 pounds..you are looking at 7.6 grains per pound.  If I were you...I would check with the bowyer to make sure shooting such a light arrow is OK.
   The advantages to a heavier arrow is that they will penetrate better on game animals, and will cause less stress to your bow.  
   They will also make your bow quieter on the shot, and also reduces handshock.
  Of course there are advantages to a lighter arrow in the way of a flatter trajectory.

Above is all true and good advice.
You might be voiding your warranty by shooting that light of an arrow in your bow.

You can kill deer sized game with that setup, but I think you might be happier with a little heavier arrow/tip setup and you would have a better weapon.

If it were my setup I would want to be around 10 gpp or a tad more. Try to get your hands on a couple 7595's and load the front up. If you were shooting around a 600 gr arrow  it would be better.

Cut to 29" you should be able to add considerable tip weight or 100 grn. brass inserts and get the  55/75's to tune. Jon is right on. My 55/75's weigh 670 grn.

In my opinion, the arrows are too light. Try for at least 9 grains per pound.

They are too light.  A simple solution is to add three pieces of weed whip cord to the shaft. Cut them the full length of the shaft plus just a little so they fit tight.  That will add about 100 grains to the arrows.  Another option would be to pack them with hardwood saw dust.  Just make sure you really pack it tight using a dowel to ram it.  

The tip weight does sound a bit light for those shafts out of that weight bow.  You may want to bare shaft tune or shoot some broadheads to confirm.

Your arrows are below the manufacture recommend weight for most bows.  That should be a big alarm bell.

Capture the data on the arrows in Stus calculator then work up a heavier combo with the same static spine.  That will get you real close for tuning.

I would up the weight of your arrows. Always be safe than sorry, light arrows are hard on a Bow. I shoot 50# to 54# with 28 1/2"
arrows at 675gr, with a 220gr grizzly up front. They fly awesome and really penetrate. God Bless Don

I shoot GT 55/75 cut 29.5" with 175g. points PLUS 100g. brass insert out of my 55-60# recurves.

Put some 100 grain brass inserts in them and see what you think.

If they fly good and are quiet enough, you are good to go. I wouldn't own a bow that I worried might blow the limbs with a 7.6 gr/lb arrow - I would get something better built.

Steve,

Would you mind providing some bowyers that will warranty their bows if you are shooting less than 8 grains per pound?

Hmmm. The bow is very quiet, there is no hand shock, and the arrows are grouping pretty well. Usually 4 or 5 inch cirlce, and at worst a 8-10 inch circle.

Maybe he did something to the arrows and they actually weigh more. Maybe he had something inside of them. I think I should perhaps get them weighed next time I go to the archery shop.

I personally like 10-10.5gr/lb.

 Way to light.Use some brass inserts 100gr as Kentuckytj stated.

Going to add some 100 gr. brass inserts to my current 3 rivers order. That will take me up to 541 grains and right around 9 GPP.

Sam:

If you bought these from someone else... weigh them first.  No tellin what they may weigh. Then, if they are light, go to work on them

Up for Steve.

Good advice here- weigh them and then add weight if you need to so they come in at 10gpi or more !
