I am sure it just depend on how far away it is and it will never be closer that 600 yard any info will be great thanks.
I use a stack of four pieces of 1/4" deck plate. It's more resilient than a single piece of 1" plate as the spaces between allow for some cushioning as do the raised hashes on the deck plate itself. The plates are then welded around the outer diameter.
Beyond 400yds I've never shot through the first plate completely with my 7mm STW shooting 140gr at 3450fps.
Of course I have access to my neighbor's junkyard and as long as I drop off an equivalent weight of steel to what I take it never costs me anything but the time, gas for cutting, and welding rods.
I hang them with a sucker rod frame and 1" Chain.
I'd probably add two more layers for something as heavy as you are shooting.
