Mid Bead...Rhyme or Reason

[QUOTE=Dave Noreen;15051]None of my Parker Bros. doubles have twin ivories, so I've sampled some of my Ansley H. Fox doubles. I have four 32-inch guns and on three the mid-bead is exactly 16-inches from the muzzle, and the other is 18 1/4 inch from the muzzle. That gun is a very straight stocked Pigeon Gun. One 30-inch barrel gun has the mid-bead at 15-inches, two 28-inch barrel guns have the mid-beads at 14-inches, and one 26-inch barrel gun has the mid-bead 12 7/8 inches from the muzzle. Three 26-inch barrel NID model Ithaca have mid-beads 13-inch (vent rib), 14-inch and 14 3/8 inch from the muzzle, and a 30-inch vent rib NID has the mid-bead 14 1/8 inch from the muzzle. Finally I have five Browning Superposed New Model Skeets with 28-inch barrels. Four have the mid-bead 14 3/8 inch from the muzzle while my 28-gauge has the mid-bead 13 3/4 inches from the muzzle. I was shooting with a fellow at the Spokane Gun Club this forenoon who had a Pigeon Grade .410-bore New Model Skeet and his mid-bead was 13 3/4 inch from the muzzle.

So, what does any of this prove?[ Dave- it proves to me that you have very good taste in your shotguns, and are a serious clays shooter. Wonder if there were standards for mid-bead placement for Fox, Parker, Win M21- or if it was done to customer specs??
