410 slug experience

[Blacktail_Slayer]

Has anyone used 410 slugs from a full choke enough to give me approx groups? What would be the kind of printing at 30 or 40 yards? And what brands produce the best groups out of a full choke?
If your wondering this is because i would like to use it for coyotes and bobcats.

Each gun will shoot different, but mine does real well with Federals. http://www.thefiringline.com/forums/showthread.php?t=229067
