I was wondering if the diamond rapture was a good bow not for this coming season but to practice when this seasons ends

I don't own one but it looks like a good bow- hard to find a "bad" bow now days. They're all good and will hunt, buyone practice and then hunt with it when you know you are ready.
Deer season isn't here yet and just because it arrives doesn't mean you have to hunt opening day. Set your stands to provide shots at a range your comfortable with and then hunt there.

Good luck in your search!
