Scotchmo, that's quite the setup you have going on there. Would you be willing to go into more detail about it? perhaps different views?
JungleShooter, I like your idea!I'm seeing a slip-on cap that would register in the hole pattern on turret, covering the existing numbers, that you could then put the appropriate tape on for your chosen pellet. You could have as many different ones as you like in you pocket. If you can give me all the pertinent measurements (dia, hole size, hight, etc...) of the turret, I'd be glad to draw it up so you can have someone local print it for you. If you don't mind, I'd like to use your idea to do something similar for my scopes.
