I came to the realization that I can shoot in the plant after hours without disturbing the neighbors. You can't hear even a .45 from the office yet alone outside. So, I figured I'd weld-up a trap. I'm sure I could bodge something together from the stock racks but would appreciate a plan or some idea. I'd let Roger (engineer) do it but the last one he built he said he had to move with a crane. I'm thinking 12" to 18" square. ( I only need a soup-can size!) How thick to stop a max of .44 at 50'? .223? I'll probably shoot .22s most due to cost. I did Google without joy.
Another ammo question. I have 200 rounds of Wolf brand .223 that are severely corroded after being in a sealed ammo box for 8 months...weird! How should I dispose? (DON'T BUY WOLF!!!)
The southbridge or PCI-ISA bridge chip can only exist with "side-band" channels to the main chipset. There is only one of these possible, and then only if the rest of the chipset supports the southbridge concept. The side-band channels do not exist as signals on the PCI bus, so I don't believe that it would be possible to do a PCI board that provides full ISA -- more particularly, support for ISA DMA. You might be able to get by with some specialized FPGA or ASIC for the purposes of a reduced ISA feature set connecting to the PCI (no DMA and with subtractive decoding for the ISA address space.)
Just a 1.5 square foot trap? To catch .44 and .223 rounds? I sure hope you have something very large and very solid beyond where you're setting up this tiny trap (like, perhaps, the side of a hill). Either that, or you own the property for several miles downrange.
I do have a whole vacant 15k' building on the other side of the wall behind the trap. This wall is 2' thick old-style block then two more walls then a hill for a total of 800' to the hill. I think I'll stick to .22s though.
I have a 1000 fps air rifle, which I shoot at homemade targets at home, using a old table top as a backstop. It is a super accurate Gamo rifle with a scope. I once killed 3 squirrels with 5 shots (and ate one squirrel, yuck).
12" of pea gravel will stop anything you are likely to shoot from the shoulder. A 1 cubic foot steel(5 sides) box with one open side covered with heavy reinforced rubber(PU truck bed mat) and a hinged top makes a good indoor bullet trap. The pea gravel is converted to dust by the bullet impacts and the gravel level gradually falls in the process, hence the hinged top to add more gravel. The rubber will need to be replaced periodically. Cheap to build and easy to maintain. Mine stops 30-06 soft-points in less than 6" penetration.
Let me tell you of a story of a friend that had a rifle. He wanted to do some indoor shooting and could do so as he lived behind his shop. I came in one day and found him draining his pool to fix a leak in it. Seems that he missed his target (a 3' square of steel sitting at an angle) and the bullet went though a concrete block wall, the wall of his trailer, an interior wall, the bathtub (two hits there), another exterior wall and into the plastic surface pool that he used for cooling water. Bullet lay about 3' inside of the pool and when we got it out, it was merely scratched up a bit from going through all of the stuff that it went through. He subsequently changed his direction of shooting so that after the bullet goes thgough the block wall it hits dirt for about a tenth of a mile. He ended up putting several more bulllets into that dirt, one of which almost missed the dirt! All that at about 50' or so for a range! With my experiences in shooting, getting off by 5' at such a range isn't shooting but rather just banging the gun but he'd get flyers like that on occasion.

A clay trap is often used for airgun target shooting. Mine is a homemade
12"x12"x3" box with about 2" of plumbers' clay in it. (I have also used regular plasticine modeling clay). A layer of cardboard on top, and tape the target to that.
A friend and I have invented a new sport -- recliner shooting. We both bought Feinwerkbau 10meter pistols for way too much money. Mine has the electronic trigger, he went with the more traditional. We set up targets on plasticene-filled 'quiet stops' in our respective fireplaces,(he is in New Hampshire, I am in Texas), and lie back in our recliners while we watch the late night cable channels and drink green chartreuse, while our wives and kids are asleep down the hall. I don't know how good he is getting, as it has been a while since we have gotten together, but I got pretty good after
5000 pellets or so...
I actually have two targets, the clay filled target frame, as above, which is dead quiet, and a metal spinner target where you shoot 4 and the
5th resets them, so you never have to get up out of the chair, which is preferred, but noisy, more appropriate for use while watching drag racing all day Sunday.
I also use a monocular as a spotting scope to verify my errors after every shot. Some sort of tripod arrangement mounted to the recliner would be a great improvement, as I keep losing the monocular in the chair cushion.
The fireplace screen hides this when necessary, so I haven't taken it out of the fireplace in probably 10 years. I do vacuum out the pellets and target fluff every year or two, whether it needs it or not.
I am waiting for 10 meter, (actually, I am really only 7 meters from the target, so 7 meter recliner shooting to become an Olympic event...
In my parents basement (think about this now), me and my buddy put a piece of plywood against the wall to which we hung the rubber bed mat out of his pops truck. Then we swiped a few stop signs screwed them to the rubber and plywood. After we did all this we then fired misc. hanguns and our .22's. We had a "range" of 25'. We did all this while my parents were travelling around the country for a month. When they got home we had forgotten to take down the "range" I came home from school one day to find my Dad "playin" with the guns. The range stayed there for the whole summer until we decided to finish the basement. The bullets did find their way into the concrete block and that needed a patch. But it held up rather well for .38's 9s and .22's for about four months. As time progressed and my parents aquired 1500 acres behind the house my buddy and I went to town building a "real" range in a valley with a dirt backstop and range tables. I had purchased many more guns by then and got an AR and Mac 11 and an AK, many a time the police would be called because of "automatic weapon fire" after a few times responding to the calls they knew it was only us. Unfortunatley, I moved away and my parents sold the house and land and I never got to fire my .50 cal there. Once we had to put out a small fire due to tracer rounds. I honed my skills in that back country and I bet to this day the lead levels are outrageous.
