I dont beleive anything you say to tell the truth.
You have more twist and turns and deflections in your post than a fulll sphagetti strainer...
You aint answered any checkfire questions I threw out for ya like a gift that will shut me down because you make schitt up and have no answers.

The answer....

Inward Inclined 10 to 15° 3 side box from last 1/4th of range distance

3 to 1 height ratio min based on tgt height at start of flank walls expanding 5 to 1 ratio behind tgt line.


Composite revetment wall pressured treated wood, layered rubber backing, w loose red clay or heavy loam/ sand and pea gravel back fill.
Bullet stop and noise abatement by interupting the bow of the sound wave with inward inclined wall.
Simple as that.......

Your scenario would never happen on military base.
Ever........
And I really dont give a flying fuqh about " Mistykins" situation or
the angle for further discussion you are hoping for to relate to it.

Even with 25m alt c or zero ranges.
They are bermed .

5° offset min for adjacent ranges.
Max range impact area for biggest cal wpn system.

The line of your question is a ridculous scenario than cannot apply on a mil base.

Dudes range is legal per fla law.
Neighbor friendly.
Nope.....

He could of planned his orientaion angle better.
And his dug in tgt area is just gonna be a pond when it rains.

But "Mistykins" would still bytch anyways.
"Nobody puts Mistykins in the corner"...
