We have a "gong" its about a 16"x14" piece of 1" steel with 2 holes in the top hung from a small rebar frame, works awesome and goes ping when the bullet hits it and swings back and forth a little, heavy but ultra durable, and I was always told dont shoot 22.'s at your higher caliber bullet plate targets, because the small bullet will hit the larger divit made by the larger caliber bullet and richochet.
