On a new bow or new set of strings I always blind bale for 100 arrows to let the servings seat in the cam tracks as well as the limbs to find their neutral position before I even start tuning. And only count the result until I shoot 10 arrows after each change that involves the limbs being pressed. On my elites the limbs are snug to the pockets but the pocket to riser has a slip fit which could be a 1/32 of an inch lateral movement at the cam. Shoot it and it will find where it wants to be. Then tune

 

There is no such thing as a break in period.

 

....Ok if that's what you want to believe. But limbs settle strings stretch and servings seat in on every new bow or new string set I've ever had some GOOD string sets seated/stretched in very quick some not so much

 

I would think it's the strings stretching causing you to re-tune.

 

"Okay, but to be honest none of that is actually "limb break in," at least as in the same context as say a string/cable set is broken in"

If you look at the limb a single entity you are absolutely correct there is no break-in needed but when they are placed on an assembly that makes up a bow some shots are needed to let the limbs pull over to their working position due to cables being offset pulling limbs and cams off of the centerline of the bow. That process for the individual components such as limbs cables and strings to find its harmony working as an assembly is a break-in-period by definition.

 

Not uncommon

I would see this when I used to tune a lot of bows. Repeat customers with the same bow in every year would change sometimes. The older PSE’s prior to them moving to the larger limbs I would find changing on occasion.

Have seen a few Mathews as well having to change top hats again to accommodate loosing a little limb deflection.

It’s not really a break in period since it’s not common per say. More just a limb loosing its deflection a touch.

Limb break in no. String and cable yes.

 

Only draw and shoot your bow half way back for the first 30 days during initial limb break in period, this will help to seat them properly.

 

I laughed so hard a had tears coming out of my eyes... [emoji23][emoji1787] I guess I'm easily amused.

I suppose calling it limbs settling would be a better term instead of break-in. Though I'm glad to hear I'm not the only one experiencing this.

So my experience, take it for what it's worth;

When you take a brand new set of limbs (right off the factory floor) and put them on a bow, I've found that the peak weight will settle a pound or two after the first few days (and this is NOT because of the string stretching and the timing changing; trust me I've checked).

To me it sorta makes sense; limbs are essentially made up of glass fibers suspended in an epoxy resin, and while the manufacturer of the material tries to make sure all of the glass fibers are tensioned equally, inevitably some percentage of those fibers are over stressed and others under stressed. When the limb is cycled for the first time, I believe some of those over stressed fibers break down and the limb actually loses a little bit of it's ability to hold energy, and after a few dozen cycles all of the over stressed fibers have broken down and only the nominally stressed fibers remain.

So yes, I do believe there is a break in period with limbs, but its already happened by the time most customers receive their bow (because it happens during initial assembly/cycling). The only time someone might experience it is if they purchase a brand new set of limbs and get them changed out at the shop.

 

I disagree.it is the string and cables settling in. Ever notice each limb has a number, defection number. How do you think it gets there, not a guess.

 

I actually asked this question a month or so ago. I had a Synergy that I put new 50# limbs on and had a heck of a time getting rid of a nock left bare shaft. I finally adjusted it out with the cable guard. Then after season I shot a bare shaft again and it was nock right! So I readjusted the cable rod back a bit and it was gone. So I either changed my grip during season, the strings/cables stretched, or the limbs set. I assumed the string/cable set should have been set as the bow was shot a lot before I changed limbs. Whatever it was, something happened. LOL.

 

Nope

 

Once a bow is put together and drawn the first time, everything would have settled into place. I've never seen a bow come out of the box and have the limbs settling of the course of several shots. String/cables may settle in but even that shouldn't take but a handful of shots.

 

I spend a lot of time at the range and don’t see a lot of people who could shoot the difference.
