Here's my question to you guys. I recently recieved a hoyt buffalo (45lbs @ 28) in a trade. I'm looking at getting some arrows and the spine calculator is really throwing me a loop. It says a easton axis 400 will work. I personally think that would be too stiff with a 125 grain tip. I had another hoyt buffalo last year and it was 50lbs@28 and easton FMJ 500's flew perfect from it.
Do I get the 400 shafts and attempt to use them and counter the stiff wpine with point weight? Or go with the 500's
I have not had great success with the spine calculator. I think I would go with the 500s and depending how light of a point weight, I might even would try the 600s.
Not sure your draw length would be the same as mine, I draw around 27.5. All my bows in the 45-46 pound range like .500 with a 50 grain brass insert and 145 gr point they are cut to 29.25.
I draw right @ 28 in. It been a while that I've had a sub 50lb bow and it was throwing me for a loop. Just didn't seem right. I'm thinkin a 500 shaft would be closer.
I have been using Traditional 600's from 3Rivers in my sub 50lb bows. As a matter of fact almost everyone at our archery club are using the 600's, including my son who has a Hoyt Buffalo, 50lbs. Most of the guys (and my girlfriend) are using 125 grains tips, but a couple are using 100's. I used to use Beman 500's but these 600's have superior flight.

500's!
My hoyt buffalo spec´s:
Beman mfx 600 30,5" 50gr insert 100gr tips.
182fps 420gr arrow at my draw 29" (44.4#)
I have a 50# Darado that I am shooting .500 spine MFX shafts with a 50 grain brass insert and 150 grain points. They fly GREAT
I'm thinking if you want to stay with 125 gr. Points you better stick with the. 500, any more snd you could probably run a .400
I have a 47@28 Bama Expi draw about 29.5, been using 3555 GT Trads with 145pts fly great!
Yeah too stiff. 500's should be fine. I actually have some CE 90's that are 9.4 gpi and .530 spine that fly really great from some of my 50-53 lb bows. The CE Heritage 500's are 10 gpi and .487 spine. Make a fantastic hunting shaft. They may just end up being an inch or so longer for you. If you are going to stay with that light of a point I would strongly suggest the CE 90. 3 rivers has a test kit which includes one of each spine.
I'm using Easton Axis 600's with 75 grain brass insert and 145 grain heads from my 44# @ 28" Super Shrew Classic Hunter drawn 28" with 29" BOP arrow. This shows light on Stu's spine calculater, but it's flying perfect for me.
What's your actual draw length and what arrow length are you going to use?? That will make a difference when comparing to what others are using. I think the Axis shafting is the cat's meow of all the carbons I've used.
I haven't done well with the Spine Calculator, either. I would think the 500s and tinker with the point weight. I find that a 75g brass insert and 125g head (total 200g) works well with that spine at that draw weight. Your bow may like something else, tho.......
:scared: Saw title...Had to see what a 45# arrows looked like. :biglaugh:
I shoot #45 and can use either 500's or 400's depending on how much point weight you want. My go to arrows are Beman ICS hunter 400's 100gr brass insert with 125gr points...30.5" long weight 505 grs.
The spine calculator works fine for me. Most of the time Stu is dead-on. Take care that you put the right values in; garbage-in=garbage-out.
My experience is that people mostly don't put the right values in the calculator.
I also shoot 45 lbs. I use Goldtip Traditionals 1535 (that is .600). Standard insert (11,4 grains), a 85 grains fieldpoint, standard nock filled up with some weight (21 grains total) and arrow length (back of point to valley nock) is 30,5 inches. My bow is cut 1/32 before center and I use a 6 strands string. I fill up the shaft with some foam (whole length) in order to reach a total weight of around the 405 grains, so I am at 9 GPI.
They fly perfect and that is exactly what Stu is telling too!
For my setup Stu says that your easton arrows are just a little bit too stiff (3lbs), but that is at a lenght of 32 inches (with insert and nock weight at 11,5 grains). Cutting the shaft would make it way too stiff indeed!
Further questions are:
- At what lenght do you cut your shafts?
- What do you fill in in the "Center-cut" box?
- How many strands is your string?
Especially the center-cut option is important.
BTW: I replaced my Goldtip traditional set-up in Stu with several Easton types with a spine of .600. They are all pretty close!
if you draw around 28" I'd say go with the 500's...possibly some 600's if available.
My 45# whip HS likes full length 500 beman bowhunters with 175 grain tips and standard inserts when drawn to 28"
Using a ff type string.
Either 600 or 500. I shoot 600 for 3-D but 500 for hunting. Either will fly well.
