RE: dry fire?
dha,
Axles are almost always bent from a full dry fire.
Also, string and cables can stretch and fail later on.
Take the bow to a Pro Shop and have them pull the axles unless you have your own bowpress and do it yourself.
If the bow has bent axles and they're not replaced, they can damage your cams and limbs by wallowing them out at the holes where the axles pass thru.
