Steve t,
I'm sorry this happened to you. As you are a very experienced crossbow user, I think you deserve the benefit of the doubt. After 40 years, most guys are mature enough to just admit if they dry-fired their bow. At least the ones I choose to be around.
I have had similar situations with manufacturers. Very often, you need to call back and talk to a different rep. I had something very similar happen to me with a scope. It was absolutely horrible, right out of the box. Everyone was accusing me of dropping it, mounting it wrong or doing something else to it, including the factory representative, but I had not. It went onto the gun and straight into test firing as soon as I got it. Not a scratch on it.
Very irritated at the accusations, I called the company back after messing with the scope more. It ws all over the place, nothing I could find was wrong. This time, I got the supervisor of the first person, as everyone else had gone home. I held back my frustration and calmly explained the situation from the start.
He listened quietly, and when I finished, he said, "I am so sorry you went through that. It sounds like it's the scope. It happens on rare occasions. You are absolutely covered by our warranty. Since the scope is new, I will email you a return slip with shipping, and we will get you a new scope in the mail as soon as we receive and inspect it. I apologize in behalf of the representative who gave you incorrect information."
I was surprised and very pleased. I printed out the shipping label, received another new scope within a week, and this one has no issues. Not saying this will happen for you, but sometimes calling back during another shift time or asking for a supervisor is worth the effort.
I do have a question, for you... How long between the time you bought your Xbow and the time it blew up? It really doesn't matter, with that particular warranty, but I'm just curious.
I've learned to test new purchases IMMEDIATELY, because too many times I've let something sit in the box only to discover that it was defective when I needed it. That sucks every time!
I hope all goes well for you.
