Well got my shotgun back from Firebird and it now runs reliably going to put a red dot on it. Any suggestions for range to zero it at? Or should I just get a fibre front sight on the rail and leave it at that?
Mine is zeroed at 100.
Or was it 75. I can't remember. Shoot 50, 75, and 100 then choose and know your holds for the other two distances you don't choose.
The only thing I could think of is just like what Mike said.
Plus I guess use slugs so you know exactly where you're hitting, other than that my friend I don't know.
