From Beretta Arms

As you can see the differences are slight, could be the amount of powder, size of wad, with or without a shot cup, size of shot cup, between the two different reports...

It's 1" to 1 yard on FULL choke not cylinder...

And it don't matter whether you use buck or bird the expansion will be about the same...

When the spread becomes to open it will allow a clay target or a live bird to fly through unscathed...
