When I move back to my house in Virginia, I'm thinking of putting in a small range in my back yard.
My lot isn't huge, but it backs up against public undeveloped land, and I could easily get a good 25 or 50y lane entirely on my property with about 400 yards of dense woods beyond that, with populated area beyond that. (The woods are kind of swampy, not a recreation area of any kind.) The zoning and local laws don't prohibit discharge of firearms, as my neighborhood doesn't meet the ordinance's definition of a "densely populated" area. I'm not interested in shooting any centerfire rifle calibers, both because of noise that would bug my neighbors, and 400y of clear area downrange, trees or no, certainly isn't adequate to contain the 1-in-a-million .30-cal round that wasn't contained by the range backstop. But I think suppressed rimfire would be quiet enough to be courteous to neighbors, and non-energetic enough to make constructing appropriate backstop reasonable and safe. Any links / suggestions / experience with rimfire-specific range construction would be appreciated. Can I do this safely with just a simple cheap commercial rimfire bullet trap, given the 400y of uninhabited swamp trees behind it? I'd rather not go to the extreme of a public range no-blue-sky overhead baffle system, huge earthen berm, etc. I've found a couple resources via Google which are interesting reading http://nssf.org/ranges/RangeResources/library/detail.cfm?filename=facility_mngmnt/design/baffles_berms.htm&CAT=Facility%20Management http://www.hss.doe.gov/secpolicy/pfs/range_design_criteria.pdf but these seem to focus on ranges intended for public consumption, that have to contend with centerfire rifles and hunting calibers and and lowest-common-denominator inbred cretin users. |

THIS
DAPAM 385-63 (aka) MCO 3570. Chapt 1 Chapt2 Chapt4 Chapt6 Chapt19 Read App B (or) C Where it states different standards for Army or MarCor: Army is the more stringent. Grab a compass & identify an 8 digit grid for your firing point; identify your gun target line with the compass. Read Data from pg 175 (note your 400yd comment compared to Distance X) Grab a Protractor, a straight edge ruler that reads in mtrs, and a 5mm pencil and draw an SDZ (you'll know what that stands for once read the reference). As a substitute for the compass and an alternative for identifying your firing point, use THIS As far as Noise.... "Suppressed" vs "db"s...... different matter... Understand that your area may have an ordinance against anything over a certain threshhold. Common sense approach is 110 dbs as a limit |
