Wow 300 nails in an hour for this gun is alot. I am a professional framer and would not recomend this gun for that kind of use. The only time I use the pasload is when I have a small punch list. Not sure how old your gun is or how long you have been using it under that much of a load, but my guess is you may have burnt it up. The only real answer for these guns is to take them to a qulified repair person.
