You do realize that a lot of the top bows use polymer limb pockets, to save weight.so a 1K bow with plastic pockets?.............now that's ridiculous
And this may also be a contributing factor. The bolts are supposed to be snug. Without it being snug it allows for slight movement, which can cause stress fractures.How much are you suppose to loosen them? I checked the one on the cracked pocket and it still had about 1/2 a turn before it was snug. And again, I can’t see how only tightening the limb bolt about 1/4 - 1/2 a turn further would cause it to crack like that, even if the lock was tight.
