Goldtip 5575 for 40 pounds

[jojotater]

I shoot 40 lbs at 27 inch draw with my Bear Grizzly Recurve. A fellow just made me a good deal on some Goldtip 5575 arrows cut at 28 inches. Will these shoot at my draw weight? They will be way too stiff as is, won't they?

[Otto]

They'll be plenty stiff.  In order to make them fly you'll likely end up leaving them full length with at least 145 to 150 gr. out front.

[Scott Gray]

Yep, way too stiff. You would do better with 3555's. You could load the front end of the 5575's with a 100 grain brass insert and some heavy field points and might be able to get them to work.

[jojotater]

I've only messed around with wood and aluminum. How do you get the inserts out of carbon? Do you just heat carbon like the others?

[Scott Gray]

Do not apply heat directly to the carbon. I have been lucky with this technique ,screwed on a fieldpoint and applied heat to the point and used pliers to grip the point and remove the insert. This may or may not work for you depending on what was used to install the inserts to begin with.

I shoot full length 55/75 with 125 grain tips at 55 lbs at 29 inches & they are just right. 40 might be too light IMO.  Mike

Way to stiff.  I use 55/75 @ 30" with 250gr up front 53# @29" draw. I have always needed a stiffer spine than most. at 28" that shaft will be way to stiff even if you front load the heck out of it.... Shawn should be around soon to reply to this

[Otto]

Can anyone explain why folks are loading up carbon shafts with so much weight up front???  

Are you doing it to add weight or are you doing it to get the dynamic spine correct so they'll fly good.  Not being critical, just want to know.

I'm shooting Black Widows, all SA models..all of em 50#'s @ 29 inches.  I can shoot 55/75 GT's, cut to 30.5 inches with 125 gr. points on em.  Bareshafted them to find this setup and they fly straight to point of aim on out to 30 yds.  I stuffed em full of 5gr./inch tubing and it's a nice 550 grain arrow.

[James Wrenn]

They will be much too stiff for any 40lb bow I have ever seen cut that short.  

Otto some do it to get more weight.Others do it because they want shorter arrows and try to bring the spine around.Many do it because they buy arrows by shaft weight instead of buying by the spine they need.

[Pete W]

far to stiff.
Get 30/45's and tune them. Brass inserts and start with 145 gr points and go up from there.
Start with the shafts long.
Let the tuning dictate the length..

Steve, I like to Front load my hunting setup. It not only will let you shoot a stiffer,and in most cases heavier shaft....but the real advantage is in penetration power.

Otto,

Some couple years back was doing some carbon experimentation and my MOrrison recurve and the BW's guys had with me, all are cut "PAST center." More center shot = more stiffness in shaft for a given draw weight it appears.

That amount of center cut requires a stiffer spine. I used 5575 cut 29.5" for 28" draw, w/ 48# limbs on Morrison and 100 gr. brass insert and 160 gr. heads.

I guess to answer the original question, YES, to increase overall weight (I like 600 gr. at 50# draw range) and to affect dynamic spine on carbons.  Carbons seem to be more tolerant in spine range than other shaft materials...

[Shawn Leonard]

Man you will need at least 350 grains of point weight to soften those babies. I am sorry but I see this a lot sayong guys are shooting 55/75s out of 50# bow cut to 29"s and just 125 up front, well take the fletch off and see how they really fly. I a amazed at what most trad guys consider good flight!! I am not being an idiot, it is a statement of fact. Look at what doc. said, and that morrison is on high performer and he had almost 30" shaft and 260 up front out of 48# bow. I myself do not care for GTs unless ya shoot the lighter spined ones out of bows up to 55#s. shawn

[DesertDude]

Like My RER 30.5" 55/75 100gr insert and 145gr point. 49# @ 28" and I draw real close to 30". I'm going to do a spine check on all the different types and sizes of carbons in the next few months. I know that GT spine is off from shaft to shaft and in the 360 deg test also. Just because a MFG says .500 or .400 spine,doesn't mean that it is. The ones I have checked so far have been off. Last one checked was a Axis 500, it spined at .458 when easton called it a .500 spine. Only true way to ensure that an arrow matches your bow is to bare shaft test it. You would not belive how much fletching effects the flight/spine.

[Shawn Leonard]

I should also say that carbon recovers from paradox so much quicker that once ya get a carbon with a .400 deflection, it is hard to put too much point weight on them. I mean I could shoot a carbonwood 4000s cut to 29"s with 225 grains up front out of my 62-65# recurves(cut past cennter) and they bareshafted perfect, but I could also add another 100 grains of point weight and they still bareshafted perfect.

Yea!I shot a truck load of those and you can't get enough weight up front to getem to fly out of a 40lb bow.I shot a 43lb with full lenth and they were still to stiff.3555 with 200gr or even 250gr with long length is what I shoot out of that bow now.

[Doc Nock]

Interesting stuff, ain't?  

Shawn,

Thing is that my Griz Sticks AK outa the Morrison are "weak" with only 75 gr. insert and 125 gr. tips cut 29" with 28" draw! Same bow...have to shim out the riser some to get good flight bare shaft ala Adcock's website testing method.  

Thing with the 5575 is that with the Morrison and the 54# limbs, I use exactly the same 5575 but cut 1/2" shorter to 29" even and only use 145 gr. tip with the 100 gr. inserts. 6# more draw weight and I only have to cut off 1/2" of arrow and can go with 15 grains lighter point weight. Go figure.  Carbon just responds differently...

Guys with them engineering stuff behind their name one time claimed you have to consider "dynamic spine" vs. static spine... whatever the heck that is! ...so the bare shaft method showed me what I needed.

I agree with your statement about "good arrow flight" too. I thought for years I'd see a "kick" out of my shafts in flight...guys on ladders, behind me, etc...said, "Nope..perfect flight". Cut off feathers from half and tried that planning method and BOOOM... found all my shafts were shooting weak...

5575 took care of that easiest.  and at 610 gr. total weight I'm liking that! Only bare shafts that fly like wires to 30 yards... I don't shoot bare beyond that!  

[jojotater]

I reckon I won't be using those boys. I'll stick with my wood arrows. They seem to fly good for me.

[Shawn Leonard]

Doc, ya have to remember that taper on the other shafts makes a big difference. Shawn

I'm shooting 3555's cut to 29" with 310 gr. up front out of a 42# @ 28" longbow,fly good.Hopefully this is helpful info. Leland
