Mid-bead
 

My eyes are starting to have issues with the mid-bead in my barrel. Any issues with removing it, and putting a temporary plug (clay) in it's place?

You are shooting a shotgun, not a rifle. Other than possibly to check to make sure your eye is in line with the rib, you shouldn't be looking at the beads (sights) when shooting. Many top trapshooters take the beads off their guns and shoot off the end of the barrel.

I'll keep my front bead. Thanks for answering the question on the mid. Good to go.
