Limb question

[bmarleyzq8]

Kind of a dumb question but what is the difference betwwen a 50-60 lb bow set at 60 lb VS. the same bow 60-70lb set at 60 lb? What would be the advantages of dis-advantages of each?

Some will tell you that a bow will perform better when maxed out for weight than one in the next weight range up dialed all the way down, however we are really starting to split hairs here.

In all reality, if there is a change in efficency it will be something in the range of 1-2fps

Splitting hairs, but when you let a bow down 10# you get a lot of air in the limb pockets and limb bolt exposure (looks funny to me).

If you let 10# off your ATA will shrink & your brace will increase, you cam timing marks will be off unless you put some twist in your string & cable to get them back where they were at full taut.

well I have been wondering the same thing.

[bmarleyzq8]

In my case I have a single cam with pivoting limb pockets and "parallel Limbs". My bow is a 60-70 pound bow, What would be the effects if I were to drop it to about 62" pounds?

Any of the hybrid cams will maintain cam timing regardless of what you do to the limb bolts.

I have a couple of Hoyts that I have been able to go from maxed out at 72# to nearly all the way dialed down 55# and the cams are still in time.



bmarleyzq8: your bow will perform fine at 62#. This is why manufactuers specify a weight range on a bow. 60-70 means you can safely adjust the draw weight between those numbers without comprimising saftey or any significant efficency.

That is good to know, I know it wasn't the case with the solo cams I've owned, never tried it on my binary bow.

bmarleyzg8, at 62# you will have the ability to tweak up or down in the draw weight range and it will also allow you to adjust each limbs tiller seperately if you should fine the need to do so when dialing everything in.


One word of warning, I have owned 4 Bowtechs and on the 3 I tried NONE would go down 10#'s if you stick to their recommended 2.5 turns out max per limb bolt.
