If you can reload STS/Nitro 27 hulls safely, then yes, you should be able to reload Gun Clubs (and Sport Loads) with the same techniques and recipes, safely.
(However, I and others on forums like these are usually anonymous, with no expertise or experience that you can verify. You might try contacting Remington for a more authoritative answer - they have more at stake in providing answers!)
