If the limbs are good, and it looks fine. Put the strings back on and try it. You can see if there is damage. I had a BassPro bow(Redhead) that had Hoyt cams and limbs. I think I dry fired it at least 3 or 4 times when I was new and concentrating on my form and shooting. I checked it out and used a couple of Harbor Freight ratchet straps to press it and put the strings and cables back on. It was and still is fine. I just gave it to a new guy the other day but I shot it for years after the dry fires. Killed my first elk with it at 63 yards.
