Thread: Reaming out Full Choke for steel?

Hi all
Just thinking of perhaps getting a second hand O/U 12g for a bit of all around use, ie gamebird and occasional clay target shooting.
Most of the guns I see advertised have a full choke barrel, and I am wondering how successful it is to have a gunsmith rebore that barrel to something suitable for steel shot.
But how successful is this process?
Would I end up with a half assed compromise that doesnt pattern very well either with steel game loads or trap loads?

Thanks.
