I have a pretty green Browning myself.
A friend and I brought it in the front door using a appliance dolly, and once we hit carpet, we slip it into place, including around 2 90* turns.
We just did the old twist the safe a little, and push, then twist it the other way, and push:
It worked great.
Didn't use anything special once we hit the carpet, just the bottom of the safe.
Good luck on your mission.
