Well, there another angle why the birds went on the great downfall. Different circles bring different very possible criteria to the table. I remember if there were weeds in the corn field the birds had a possibility of flushing for the drivers instead of the standers at the end of the field. Weed free corn fields the birds were runners. I have been to the Williams Gunsight shop a few times. Back in the '70s my first job out of HS was at a broach shop that broached some of the parts for Williams sights. So, if any of you have Winchesters, maybe Marlins or Glenfields from the late '70s to the '80s I may have may have set up and did QC on some of your sights. I guess that would account for if your gun shoots good or doesn't. If the sights were crooked it must of been 2nd shift. lol
