I recently bought a 7600 with problems.The breech opens by itself when fired.any thoughts or solutions.It has been back to the service center once thanks Al.

If your talking about the action starting rearward after firing that's normal. There was a discussion about this a short while back.

If im not mistaken you hae the pump action .35 correct? I have one and its perfectly normal for the action to reward after fired. I beleive Remington was the first to come out with the "Speed Pump", Winchester followed this by putting it on their shotguns. My 7600 .308 does the same thing.

I've got a 7600 35 Whelen also. That's normal, all pumps-rifles and shotguns work that way. When you pull the trigger it releases the lock up. If you don't pull the trigger you have to use the release button.
