here ya go:

I just guessed at a 26 inch long arrow since you didnt' say. I also guessed at 10 grains for the silencers

at 51 pounds
.5926 is suggest all around spine for you, .5842 is for hunting

at 54 pounds

suggested huntign is .5565

the Goldtip Exp at 3555 are .480

Need more details.

I assumed you have the 80% letoff cams.
Do you have the 80% or 65% letoff cams?

26-inches is the draw length?

26-inches is the raw shaft length also?
(not including the nock or insert length)
That's what I also assumed.

2006 Diamond Rapture with 80% letoff
Assumed Draw Weight = 54 lbs
AMO Draw Length = 26-inches
Raw Arrow shaft length = 26-inches

Assumed 100 grain field tip
Assumed 2-in Blazer vanes

On the "Spine Match" tab on top,
I clicked the "both" filter for Search Filters.

Your sweet spot will be between 54-56 lbs of draw weight.

You need to go to 100 grain field tips,
because the 75 grain tips are a little on the light side.

You really need the 80% letoff cams.


If you are using the 65% letoff cams,
then this arrow combination is way on the stiff side,
and you need to consider the 145 grain field tips
at a draw weight of 54 lbs

or

100 grain field tips with 60 lbs of draw weight
assuming 65% letoff cams.

Right now my shafts are cut at 27.5".

I am shooting the bow at 27" right now but I am going to take it down to 26 because i feel i am leaning back too far and the nock is about an inch behind my eye.

80% let off

I am pulling 51# right now but Ive been considering upping the poundage to around 54# for hunting because I can comfortably pull it straight back.

Here's what I put in and what it came back with.

'06 Diamond Rapture
26" true draw lenght (27.75" AMO)
51#
15 grain peep
5 grain d-loop
3 grain nock point
12 grain silencers
75 grain field point
27.5" arrow (raw shaft only)
Blazers
Wraps (12 grains)

With this setup it recommends 0.4784 spine - the Expedition Hunter T480 is a 0.480 - so it would be right on. If you go up to 54# draw, it will be just a little weak.

This setup only gives you 44 pounds of kinetic energy, so a little more draw weight, a heavier arrow, and a 100 grain tip certainly wouldn't hurt for hunting.

If you go by what I got you will be (at 51#). See if Nuts&Bolts chimes in again - I trust him more than I trust myself.:eek:

Ok.

Good catch by [email protected]

So, when you say your DL = 27", you actually mean your true draw = 27"
and then you are currently shooting an AMO draw length of 28.75"
and that you are considering dropping down to a 26" true draw = 27.75" AMO draw length

Diamond Rapture at 80% letoff

GoldTip Expedition Hunter 3555 shafts
where the raw shaft length = 27.5 inches
(not including the nock length or insert length)

Keep the 75 grain field tip.

Using 2-inch Blazer vanes

Shorten the AMO draw length to 27.75-inches.

Drop the draw weight to 45 lbs.


The Expedition Hunter 3555 shafts are too weak for you.

If you upgrade to the Expedition Hunter 5575 shafts,
and upgrade to 125 grain field points / broadheads...

then, 2-in blazers, and a raw shaft length of 27.5 inches
and an AMO draw length of 27.75 inches (true draw of 26-inches)

will work for you at a draw weight of 52 lbs.
