I have to do this on most factory Remington barrels and I don't know it would work on a Ruger but I chuck the barrel in the lathe and use a parting tool and make a cut in front of the recoil lug the depth of the lug to relieve the load on the receiver face. I can usually screw them off by hand afterwards. Makes the factory barrel unusable I usually would never use on again anyway.

You'll need a stout rear entry action wrench; the stainless steel one will get twisted. PBike257@gmail.com makes a good hard one. You might want to take the action out of the stock and soak the barrel/action with Kroil or a good penetrating oil and then apply the muscle. You can also add heat to the action with mother, wife, girlfriend's iron for a while.
