In my local shop a few weeks ago we did the following test: We took a Hoyt RX-8 Ultra 70 lb max backed down to 55 lbs set at 30.5" of draw, 85% let off and shot it through a chrono. Took a Hoyt RX-8 Ultra 60 lb max and backed it down to 55 lbs, set at 30.5" of draw, 85% let off and shot through a chrono. They measured the same exact speed. We then measured axle to axle and brace of both bows - within a 1/16" of each other. I shot them both, and was pounding X's at the indoor range with both. So, at least in the case of a Hoyt RX-8 Ultra, backing down the limbs quite a bit had zero effect on performance or accuracy. Thanks.

I noticed that the first bow has a string stop and the second one does not. That would automatically allow that string to come forward more. What happens when you test them both with a string stop?

My heart skipped a few beats watching you twist that string my god !

Thanks coach

Remember all the gold Hoyt Trykons. Perfect example of a bow with not enough string tension at rest.

I asked this question on AT n every one said that I would be fine backing a 60 to 50lbs. As no shops had a 50lb to buy. So far it’s fine out to 40 yards. Going out to 70 tomorrow

I’ve been into bows and shooting for 3 years - First time seeing a bow without a string stop on the riser (2nd bow)- I figure that would help.

I guess this is also a factor going from a 80% to a 90% let-off right? Which means setting at 80% let-off will be more forgiving that 90%?

I agree.

John, don’t the manufacturers test their bows within the limits of their specs? I would assume hen they say you can back it out 3 turns it would still perform as intended.

All fine but what do you do when you draw 34 lbs on a 40 lbs bow, there are no bows max 35 lbs

At the end of the say, you shoot ahat you have to shoot. What he says is correct, but I personally don't see any issues shooting the bow in the mid range.

Women and kids, yes, but shorter draw lengths, so less effect. I'd say a newb adult man with a longer draw length that has backed the bow down is more at risk.

Would that happen if you played with draw length too?

No because the tension on the string stays the same no matter the draw.

Only thing you could do is tension at full draw by manipulating the stops and or module

Since I don't have too many bows to play with, I'm hoping you can answer this or perhaps someone else here can. Wouldn't a bow that is maxed out at 70 but backed down to 60 and a bow that is maxed out at 60 have a relatively similar string tension? In my head I can only see it being an issue in extreme cases, mostly with the "grow with you bows" (infinite edge, crusier, ignite, etc.) where they are backed down to extremely low weights.

So, if you want to shoot 65 # with a PSE or Bowtech bow, you can't, unless you sacrifice accuracy. You need to buy an Hoyt, a Mathews or an Elite.

Well you say that, but since PSE have several limb options for different cams, you just need a swap sometimes. I've got 2 Citations and one is a 65lb and I'm almost certain that's because that set of limbs came off an SE cammed bow while I have EM cams.

@@liamboyle9199 I understand sometimes you can get a combination like the one you say, but, let's say I would like to shoot an Omen at 65 #, with the standard cams it comes from the factory (EC2 ?) , how can I do this without backing off the limb bolts 5 pounds ?

It won’t if you have a string stop ,and why you using your wife’s bow for this demonstration,why not use your own bow.

Tell me how the string tension at brace would be different between a 60# bow maxed out and a 70# bow turned down to 60#. It won't be different. You can look at draw force curves if you take the same model bow and have one maxed at a certain poundage and one with higher deflection limbs turned down to match and they are identical and velocity is identical or dang close. As far as face pressure and string tension at full draw, that has nothing to do with the limb bolts being turned in or out, it is all about letoff and holding weight. You're full of crap on this one, Dud.
