Lots of great talk, but anyone here have access to the US military's sandbag guidelines? I don't, but have dim recollection of 20 inches of sandbag being considered minimum for ordinary old 7.62 NATO stuff.
Yea, this is one of the reasons I was down on using a dirt pile - dirt settles at a (roughly) 45° angle. This leads to runoff problems, not to mention ricochet problems when it freezes. Sand would probably not freeze, but it would settle more.I have a range with a dirt berm on my property. I had to lay heavy logs across the dirt berm to make a wall about 7' high. In the winter the dirt freezes solid and since it settles at about 45 degrees most rounds were richoceting straight up. The logs even when frozen solved the problem.
