Chamber Gauge ?

[Dan]

Am I correct, it appears to me that the velocities were taken at a range of 100' from the muzzle. If you were to extrapolate that what would the M/V be three feet from the muzzle ?

You would need to know shot mass per pellet , surface area, drag, air resistance , but I think you can take an educated guess and consider the muzzle velocities to be about 1150 to 1200 fps. And also consider that from 1890 to today, the standard trap load is a 3 DRE 1 1/8 oz running at about 1200 fps. Parkers , irrespective of barrel steel , were made to shoot at least these loads. Parkers were not delicate guns.
