My local range had a 100 yard and 200 yard range with steel plates on wires. The 100 yard range had very small three inch plates. You could only shoot at the plate off-hand, no bench rest shooting.
I took an extra gas cylinder for my M1rifle and installed a target block so I could use a target front sight with round apertures for steel plate shootings, this really worked out fine.Attachment 81915Attachment 81916Attachment 81917Attachment 81918
