Not for me (Thank the Lord) but it has been mentioned on the H&R forum that one of NEF's barrel smiths had a heart attack. I emailed "Gordon" in customer service and let him know I'd be praying for him. Don't know his name or condition.
Here is Gordon's email. Actually it is the companies but I thought you could mention Gordons name.
