how to sight in a slug barrel firesight mounted on rib?
I installed a Williams firesight on the rib of my Remington 11-87 12 ga. It is adjustable up and down and left and right...I want to go sight it in soon, but am not sure where/ how I begin. Is there a proper way to adjust these things? I have no idea how where to start?? If I am high and left, then do I make an adjustment up and to the left? Thanks for all help. I have a special rifled sabot Rem choke tube...I bought three different boxes of slugs totry...lightfield, winchester and rem. Thanks for any and all help.
