Back stop height

Some research undertaken by a committee member has established that if we were to build a range on flat land with "no danger area" then we need a backstop 23m high! Is this correct for a 100m rifle range? I know it is lower for shorter ranges. Does anybody have any experience of this for civilian ranges?

thats a serious height! and it will most likely involve a much wider base are to support it! I would imagine IanWR would be the man to talk to.

Mike get someone to give JB arbroath club a shout i'm pretty sure he got a copy of the range criteria thingy.Perhaps restricting 100m to prone only might reduce the height required.

Get a copy of the range consruction notes from the NRA or NSRA. There are ways around it such as the use of baffles.

I've got pdf's of the MoD Range construction pamphlets - interesting reading.
I am sure that I found them online

Aye by the time we've piled up that amount of earth there would be no room left for the range.

Start with JSP 403 available online

None of the ranges I ever shot on had a 23m hight back stop. (Unless it was a mountain!)
There are ways of preventing the escape of projectiles which migh go over a back-stop, as someone has mentioned, by the use of baffles.
The NRA's consultant on these matters was laid off with the rest of us old buggers, I don't know if Iaian now has this responsibility.
There are a number of retired army SASC officers who now offer themselves as 'consultants' but that route will cost you money.
PM me if you think I can help.

thinking about it, I'm sure the Naval range at Portsmouth had/has at least that high a backstop, it proved not high enough to stop one sea cadet sending the back end of a Bren mag over the top towards Gosport when I was there on a marksmans course in the mid seventies sign01
