    I need to build a backstop inside a steel barn, with a dirt floor. Backstop will hold several hundred rounds of handgun ammo a week.

    Thinking about three layers of bridge planks, staggered, so the seams do not line up, sandwiched with fence T Posts. May also think about solid railroad ties.

    Thought about sandwiching sand or dirt between plywood.

    Your input is very welcome. I have one week to build something. Would rather build it once, and have it done with, rather than fussing with the project again in a couple months.

    This video shows something that seems to work well.

  3. Tires filled with earth, two rows staggered.
     
  4. I kinda like the sand sandwich idea. I assume that would be just to catch strays, otherwise it would get perforated too soon.

    A dirt sandwich sounds like it would rot.

    A railroad tie sand sandwich would be awesome. Cross-tied together, and held with some supports so it doesn't tip over on someone.

    These are just thoughts. No experience doing this, other than outdoor dirt piles :)

    Pick up fifty more RR ties tomorrow. Ties are two deep. One tie stops a .40 S&W hot FMJ.

    Going to build wrap around sides to make it safer just in case we get a shooter with poor muzzle control / finger control.

  6. What about up and over?

    My club with an indoor range occassionally get bullet holes in the ceiling, but there are no houses near by, and the back is woods.

    Obviously don't want upward shots, thus security cameras to identify and kick out the offenders.

    But my point is it happens with unsafe gun handling, so the range should be ready for it.

    If they keep muzzles under control, and the only oops is up, down, or side to side, we are OK. Dirt hill behind the wall. If someone NDs a round from their car to the barn? I am on a busy road, houses not far away 1/4 mile. In that regard, I am no better off than a range in the middle of town.

    Would be nice to be setting in the middle of 9 sections of Ground. My 7 acres is far from that.

  8. Good chance of shots (eventually) at 30 degrees, just over the backstop.

    I'm just mentioning it. Maybe that back wall or ceiling can be layered with enough plywood (or something) to slow down those few errant shots over the backstop.

  9. I have never been in an indoor range that has not had some "blemishes" in the ceiling.
     
  10. AR500 Steel plate at 45 degrees to deflect rounds down into a sand box.

    What might the price of a 2` x 6` piece of this cost?

    Also thought of using RR ties at a 45 degree angle. What would not capture, would deflect down. I have a dirt floor.

    This weekend we discovered 22s were sometimes bouncing off the straight up and down RR ties. Not a good thing.

    Picked up another fifty RR ties. Those suckers are hard on the back.

    Amazon sells a grab tool for moving firewood logs that is a big help. I ordered a second one. Thinking two of these, and two men could more easily move a RR tie from one place to another.

  12. For an angled side or top deflector Ar 500/550 in 3/8 in or 1/2 in is expensive(I make targets) however a cheaper solution is 3/16 or 1/4 in mild steel with rubber cheapo semi mudflaps glued on using pl400 in a shingle type fashion. This set up will stop some cals straight on, but not recommended. Make sure the rubber has gaps or ribs of rubber and not glued on flat. Bullets hit thru the rubber, deform, and are caught trying to bounce between the layers. I have even done a multi layer system for 223 straight on.
     
  13. For something to shoot into, in front of your upright RR ties wall, perhaps it could just be a layer of softer wood or sheets of plywood that get replaced every so often?

    Placed an additional three RR ties behind and leaning on targets at a 45 degree angle. Used tie down ratcheting straps top and bottom to pull then together. No seams.

    Now bullets hit the ground. Made a RR tie bullet trap. Three RR ties and two tie down straps, twenty bucks.

    See how many classes three RR ties can last. Rotating the outside ones to the middle, maybe a year. Will see.

  16. Took my CCW class at an indoor range. The classroom was on the second floor, over the range. Kind of interesting hearing somebody pepper the underside of the floor we were on while firing a Thompson.:wow:

    If you are letting other people use the range, you need to count on some of them being idiots who can't control a gun. I was shooting one day, and the elderly woman next to me could barely get her rounds on paper at 3 yards.
     
  17. At our range (commercial Indoor): My wife is 5'2" and not allowed to do head shots on silhouette targets. Some rounds hit the ceiling even when her aim is good.
     
  18. I believe you, but that makes no sense at all. There's probably 6' guys who get into some kind of FBI crouch when making their shots, putting their muzzle lower than your wife's.
