Glad all are safe.
The only thing I'll criticize is that you "chambered a round" when you confronted the guy.
I'm not one to criticize anyone for keeping an "unchambered" firearm in the house (kids, non-shooting wife, etc.) But knowing that someone was out there, I would have chambered a round immediately. What if the guy had been armed and ready to shoot, while you were not? The whole ordeal could have gone the other way in a heartbeat, with him having the drop on you. Where would that have left the wife and kids then.
Keep your firearm safe as you see fit, but have it "ready" when needed.
