Some help with my backstop. The disance is 100 meters. How high? and how wide? Theres nothing but trees behind that area of our property. so, I was thinking20 meters long and 3 meters high. Sufficiant or not? Thanks;)Take care of yourself and all of those around you.
What is the nearest structure in the direction you are shooting? Do people/kids play around in those woods? Is it all your property?
My suggestion, having limited experience, is… better safe than sorry. If you can get some fill dirt and build up a berm about 8 feet high, and however long you want, I’d do it.
Rounds travel far, and you may think that trees would stop any strays, but what if one slipped through?
I would, at the very least, do a complete check of the nearest roads, houses, populated areas, see if there IS a back stop somewhere back there.
Watch the slope of the backstop…
I am not a civil engineer but no matter the height, with the wrong slope you can skip rounds up the backstop…
If you can build a 10-12 foot high vertical wall of railroad ties with a good bit of dirt behind you are probably fine.
Other solutions exist – mine is just what should work nicely.
Isnt NRA standards 12’ high and the same depth? I thought I read that somewhere.
Thanks guys!I appreciate the info,Better safe than sorry seems to be the general concensus. I like the 12’ number, and as far as other structures or pealpe. I have two neighbors In that general direction At least 600 meters, but mostly woods, corn fields and cows. Take care guys;)
When I was about 5 my dad added an additional 1800 sq ft on to our house(with full basement under addition to connect to existing), plus built a 100ft long x 70ft wide barn since we had just gotten new farm equipment and our older barns were no longer sufficent about 4yrs later.
We had the dirt piled up and shaped in to a 18ft high 50ft wide U shaped hill that we use as our back stop.
We went this high and wide as its just open farm ground in every direction around us. But we got our selves a damn nice 200 yrd range outta the deal.
I just built a 25 m range in the backyard (all the room that I have) made a box 4’ high x 8’ long and 4’ deep filled with clay/dirt/and hardwood logs. I use it many for .22 LR and centerfire pistol (up to .460 S&W) and of course 5.56. I did dig out my out Field Engineer Manual (FM 5-34 if I remember correctly) and it stated for direct fire you need 42" of clay to stop 7.62mm for foxholes. Haven’t had anything shoot through yet and will continue to improve whenever I stay home long enough.

It’s interesting in how little sand it takes to stop a single bullet.
Sand Depth Test
A permanent backstop needs of course a thicker depth.
