I got a hold of a piece of 1/4'' steel plate from a friend of mine,I am planning on using it as a backstop(it will be angled down so the bullets deflect into the ground).The other day I shot my 300 win. mag with 110gr. V max's at it from 100 yds,and it went through it like it wasn't even there!How far away can I use 1/4'' steel without the bullet going all the way through?I know the bullet probably doesn't go much farther after it goes through the steel,but I don't want to ruin my steel plate.
