RE: are my limbs cracked
I would say you definately have a crack forming and it needs to be addressed.
Any dealer should be able to take care of it for you,just explain the situation and let them know that you are looking for a new shop to deal with.
To your question,yes a press can cause it if it isn't being done properly. If your last bow and this one show the same crack,I would say that the same thing caused both.
