I'm working on setting up 1400 yard range and I'm wanting to do a 2' x 2' steel every 100 yards. I have access to a cnc plasma cutter table that will cut anything and is roughly 8'x10' so full plates are possible. Does anyone have a good source for plates of steel and know what steel I should get? Fast 22 cals with hammers to 338 cheytacs will be shot at them. I'm in Oklahoma so closer the better.
