This 3/8" plate was on the 200 yard berm, and this was how it was found on the ground. A .338 bullet was found near it:
The steel plates on the 50 and 100 yard berms have also been shot to pieces.
The steel plates purchased by the range, using your dues and donations to the Rifle Range, can withstand pistol and rifle rounds up to about 7.62mm (.308). Bullet velocity should be below 3,000 fps at the point of impact (to avoid pitting), and less than 3,500 ft lbs of energy at impact. They can generally be used with large calibers at 300 yards and beyond.
The posts are being removed from the 50, 100, and 200 yard berms for use on the Action Range, once the safety improvements are completed. Only the 300 to 800 yard berms will have permanent steel targets.
