My range is across a flat field….300 yards. I have a 500 gallon steel barrel filled with dirt and behind the barrel have a 10 foot tall mound of dirt…..never seen any bullets go thru the barrel into or out the mound of dirt, there have been thousands of rounds fired. Another good backstop is a mound of fallen trees stack up using my Kubota to place them real tall with a mound of dirt for safe measure….cheap and effective.
