Hi all, I live in an apartment, and so the problem I have is that there isn't safe direction (neighbors on all sides, except up). After doing a bit of searching, I've found several people claiming that you can fill a 5gal bucket with sand, and use that as a safe direction/backstop (aim the gun down into the sand). I have two questions about this: 1) Has anyone actually tested this? If so, with what ammo? Can it stop JHP 9mm +p+ (coming out of a Glock 19)? What about FMJ +p+? 2) What type of sand is best? I filled mine with about 60lbs of "play sand" (ie the type you'd fill a kid's sandbox with). Home depot also sold "tube sand" but I thought the grape-sized rocks might create a ricochet hazard. 3) Do you think I could put a thick piece of steel below the bucket to make sure nothing gets out the bottom? I'd rather risk it ricocheting back at me, than risk it going into my neighbor's apartment. How thick would the metal have to be?...and where could I get it? Sorry if this has been asked before, but I couldn't find anything using the search function (I've read about plenty of people making them, but nobody actually putting it to the test). Also, really I'd just prefer to test it myself, but I live in a city, so I don't really have a place I could test it out. Thanks in advance! EDIT: This isn't for target practice! This is to be used as a safe direction for when I need to pull the trigger on my unloaded glock prior to cleaning! Sorry for the confusion! EDIT: Added "safe direction" to the title. Hopefully that will prevent additional confusion.
