My experience is that the finished weight is between 2 and 5 ounces less, but I have seen at least one that I actually had to weigh because I thought the stamping was incorrect. They removed 10 ounces of solder and steel. Also, I believe the unstruck weight is pre final boring, so one could make the assumption a very open choked gun may have more than a few ounces of material removed.

I compared several 10 and 12 gauge guns and found them surprisingly consistent as to weight removal. The outliers were the light weight guns but there was very little variance in barrel ID. They seemed to be very consistent as to final boring. I believe the difference was mostly striking the outside.
I actually considered the chokes at the time. I just checked again and a 12 gauge barrel having a 0.040 choke 3" long reamed out (assuming a straight taper) would only amount to around 0.5 oz or so a tube, depending on the tube alloy. It looks like going from a F/F to C/C would only drop a 12 gauge barrel set by 1 oz; quite a bit less on a 20.
