Title: A little help with spine for light weight bows.
Post by: Terry Green on July 21, 2022, 07:04:33 AM
I'm going to get a couple of 'test' arrows to take on the Laredo Tusk Roundup and other adventures for people to play with. I already have some 400s so what spine would y'all recommend for guys shooting 45-55# bows?

These will be carbon arrows.

Thanks.  :campfire:

Almost all of my bows in that range like a 500 spine with point weights ranging from 125-200 grains. My arrows are 31"

500 spine usually works out best for bows around 45 to 55 pounds.

I'm shooting 340s for my 50 and 55lb bows.  Randy has me a low 40s unit coming I'll use for 3D and I'm planning to hunt a little with it as well.  Texas whitetail aren't too tough.  But I'm hoping I can run 400s through it.  I ran it through the calculator and it looks like it should.  Hope so cause I have 4 dozen

.500's are fine in general for that weight range.  If a person shoots EFOC broadheads, and/or has a a longer than normal draw length, sometimes .400's work better.  I believe you shoot 175 grain broadheads and don't use heavyweight inserts, so you should be fine with .500's.

Thanks Dave, the 500s aren't for me, they are for other hunters going on the Laredo Tusk Roundup that shoot 45-50#ders.

Thanks everyone, looks like 500s it is.... I'll get to work on that now.  :readit:

Terry: As you know, I shoot 45 pounds most of the time.

If I am going to use 400 spine arrows, I need to load up the total front-end weight to 325-350 gr or more for a 29.5 to 30.5 inch shaft. (this is a combo I have been experimenting with recently)

For 500 spine, I will load the front end to about 225-235 for a 29.5 inch shaft. (this is my regular hunting arrow)

A lot depends on shaft length and what I am looking of as arrow weight once everything is put together.

In general, A 400 is better for 50 pounds and above, while 500 is better for 50 pounds and below -- given the ability to adjust the front weight with insert weight plus point weight until the arrow shoots well.

Another vote for .500 unless you are going with a heavy point

I got the 400s already  :campfire:

We are going to have one heck of a Sponsor representation at the Laredo Tusk Roundup.  I'll post that in a bit.

T, I'm not sure on the spine, but for my 50# bows, they like 2016's

Two Kanati longbows 56"37&40@26. 500 spine cut at28" with 250 up front. On paper I should be shooting 600&700 but in real life this is what shoots.

I have both my daughters set up with 500 spine with 145 grain tips. both shoot mid 40#. Oldest only draws 26" youngest is closer to 28".  Both have good flight with theirs setups, someday when they aren't so busy they may actually get a chance to hunt and kill something!!!

You already have .400's, so all you need is a few .500's and maybe .600's. I'm shooting right at 45# now, and a 30" .500 with 225gr up front tunes very well.

Three of us are using 500s out of 43# 48# 53# with 250 grain headweight
I think all three are 29"

My two bows are cut to center with a thin side plate. How are some of your bows cut?

Good to know Cory, I shoot 29"s... but got 30s for the group to make sure everyone could shoot them, not sure if James D can at 31 but will see.

Sorry, I'm no help there, I have never kept up with that, have no idea on any of my bows and have never been concerned.  :campfire:

Terry it matters. Most times cut past center you can go stiffer. What bow you shooting?
Title: Re: A little help with spine for light weight bows.
Post by: Terry Green on July 22, 2022, 09:23:31 AM
Buckey, I've had 27 different bows and I have never been concerned.  I killed animals with just about every one of them, and they all shot where I looked and with the same exact nock point. I have also shot the same arrows, except for a few exceptions, for the last 19 years with heads from 150 to 225 grains out of bows from 55 to 78#s.

I have also shot chartreuse 3 and 4 fletch forever for more than one reason , but one is that I can see arrow flight really good.  I never have had problems running 4 blades through just about everything I've killed unless I hit the off shoulder or off upper leg bone from quartering away. I've also shot pheasants with 2 different bows the same day.(had to kill one for a new Sponsor's bow and the other one was a Mohawk Rob Distefano had made for me) I killed 2 with each bow that day.

All I've ever really done is change head weights a few times to get the flight I wanted.  But most every one of those bows where shooting a 175 grain head on a 585 grain arrow.

Bucky I've shot longbows and flatbows since 94 and I forgot about "centershot" or wherever they cut these things to.
We have a lot of Robertson longbows and Holme Made if that helps you find out.
I suspect longbows are 1/8 short of center and I think a lot of these hybrid longbows might be to center?
But yeah I stopped paying attention decades ago.
Once I get a bow arrow broadhead dialed I'll go a hundred animals without changing a thing.

Out of my Widow PL's, Liberty Chiefs and Poison Darts , all 50# @29" I'm exactly the same . Great minds .......

Sorry, I missed the 600s Bisch said....... I'll need to find another Sponsor for those as these are being donated for Tradgang usage/testing on hunts.  I don't want to go back to either of the same guys for more. The 400s we donated a couple of years ago by the same two, and they were find with a couple of 500s, but I don't want to 'push it' if you know what I mean.

We have quiet a list of Sponsor participation for the next Laredo Tusk Round Up, and I'll be posting that soon.

Thanks again.
