Need some help with berm construction

[LockenLoad]

I would suggest higher than 5' if you can. We did 5' at our range in MT and we still had strays going over the top from the pistol range and the rifle and trap shooters were complaing about hearing the whizzes over head.

I was thinking the same thing

Check the NRA site. They have a pretty good site for range building with minimum height's and thickness's for different heights. Not sure what they would consider minimum for a side berm, but, if I remember correctly, for an end wall berm it was 12' tall minimum and I think the base was supposed to be the same width as the total height.

Interesting stuff. Here's a link to the manufacturer: http://www.hesco.com/US_CIVIL/index.html

Those are a definite possibility.

Could you build two parallel walls with cinder blocks and concrete, say 12" apart and fill between them with soil? Seems like that should work. I mean, you don't need to stop RPGs, just the errant pistol and rifle round, right?

[orionz06]

these are only to be dividers for bays, and not backstops (but need to stop bullets)?

Check this site out, it might provide some info to you that could be helpful:

Hesco's are awesome. Sort of like building a man sized sand castle.

Also try the old FM 5-103 Survivability. Google it. It has lot's of designs for bunkers, berms and other fortifications.

not the prettiest thing, but have seen it work in other places. Drive posts into the ground then stack tires on the posts (fill each tire with sand). use a double row, staggered. easy to replace tires if they get too shot up. keep some spray paint handy to help with the appearance. good luck

For that length and height you are going to need A LOT of material. Tires sound like a good idea since they will be easy to come by because it costs money to dump them. Old railroad ties can be found, even if semi rotted they can make a retaining wall/walls that can be filled with dirt.

Kinda depends on how nice it needs to look, and how much you can spend.

If this is a barrier between bays that it sounds like, cinder block would be your best bet for size, but you're going to want at least 7', not 5. 90 blocks ($180) per 8" row.

They use this exact same setup at Ben Avery in Phoenix. (Site I found with a bad pic) It cut down on errant rounds, but the walls eventually get ate up around the 50-75yrd line because pistol shooters on the ends with targets close in tend to shoot into them quite a bit. The range rule there was that they always put pistols towards the center if possible.
