My only concern is someone shooting high, whether they know it or not.I shoot down into a ravine also. There is absolutely no chance an errant round leaves my property. It's good piece of mind.
I’m still shooting down into an old gravel pit partially filled, but you can shoot up.
I assume this addresses the shooting high problem?I would consider an "eyebrow" or 2 at the firing line. MCFG and Atterbury have them for ideas on what works.
I more back and forth and side to side, so an eyebrow wouldn’t work for me except at the bench at 100 yards.
