The Birchwood Casey Double Mag Spinner Target is a two-disc spinning target for big-bore pistol shooters. Start with the easier 4.25" circle, then move on to the more difficult 3" circle for challenging practice. Both targets are made from 0.38"-thick steel and are heard and seen moving when the targets have been hit. If cratering or bending occurs from use, simply turn the target around and shoot the reverse side to straighten it. Center fire handguns up to .44 Magnum. No rimfires.
