Some of the larger multi-point sockets seem to have more than a mm of play in as standard anyway.
I'd probably give it a go manually - a constant force, rather than impacts from a gun - although it probably wouldn't round it off completely, and it won't matter on the one being thrown - but it might on the new one if you need to get it off again.

I have used a 6 point 30mm socket on the windy gun for this with no problems.
