The following is from my experience only. I'm sure better informed posts will follow.

That looks pretty standard. As you reduce range from 100 yards the damage will increase exponentially. A little shorter in range and you will have craters. By 150, you damage will be almost non-existent. Velocity destroys your steel more than anything else. I do not shoot any rifle (except pistol caliber) at steel less than 100 yards.

I am REALLY conservative when it comes to shooting steel. Targets I use for handguns at closer range are separate from those used for rifles. The flatter the surface of the steel the less likely anything comes back at you.
