Wynne, we’ve been using them at Palo Alto Range in La for about 3 years. Makes things much easier.
Yeah I don’t know why the entire 600 yard target is called a “center” but it is.
I guess because a regulation target frame (I’ve only seen them in one place, Phoenix), is 6 feet tall. Maybe 6 feet wide, I dunno. Like I say, only seen em once.
