Indirect Fire Weapons

Has anyone thought about the use of a improvised indirect fire type weapon for home security WTSHTF?
Not sure if it would be feaseable. Maybe using a type of aerial firework. It might not kill many but it would maim for sure.
What do you think?

There is, likely, a local law that covers that and makes you liable.

All you need is 3" steel pipe.A cap with a hole drilled in the exact center.
A bolt ground to a point screw in bolt then fill cap with lead attach to pipe.

You need a 2" nipple 2 caps 1" nipple (I believe).
Braze the 1" nipple onto 1 cap.drill multiple holes in 1" nipple.
I recommend filling the 2" with sand.

Then take a 12ga blank that you can make on a reload press.
Insert into 1" nipple.
Be prepared to adjust bolt as needed.

And you have a 3'' mortar.

I will double check my info on the 1" nipple as long as a 2 3/4 12ga fits you should be GTG.

I happen to own one and such. I feel that an indirect weapon offers many benefits especially with the technology.

For me, part of my home defense plan is part posturing/show of force, part escalation of force. I'm not looking to make more enemies than I can defend against. As is, there are multiple devices that provide indirect capabilities with a myriad of ammo types.

Are you looking for a weapon mounted device or a free standing one?

Rebar for a bipod.

I'll get back on length of 3" pipe.

Have fun.

Meet me in Farmington for a field test.

Unless you have a way to manufacture an exploding munition then it doesn't pass the sniff test...

One would have to experiment on that end.
The rounds would be like cannon balls IMHO.

I would not want to be hit by one.

How explosive would it need to be to be worth it? There are already kits to make home made airburst type "fireworks". Adding fragmentation would certainly make it effective as an anti-personnel option, especially when trying to flush someone out of your dead space.

so you're talking about a 'bowling ball' mortar? or maybe a grape shot?

The 'submunitions' will need to be heavy enough to flush someone out of hiding...maybe semi tractor ball bearings as grapeshot...

Flash powder was used in the old Mk2 pineapple grenades. AFAIK, people thought they worked well enough creating casualties. Given the reduced effectiveness of improvised fillers, I'd suggest going to 4" piping for effectiveness. 4" schedule 80 pipe has a working pressure of roughly 2k psi and a bursting pressure of 9k psi. Given suitable expansion room, 12ga blanks plus a suitable propellant charge would make a perfectly fine mortar propellant. Alternatively, you could use high pressure air. Research "dynamite gun" for historical examples.

If you're talking a long term scenario defending a homestead or something, you could cast shells from something like zinc. Lead is also a possibility, although considerably more dense(less range). In either case, you'd want to add a fragmenting jacket or similar. Fuzing would be problematic, perhaps a time fuze would be easiest if not safest (research: "firing at 2 strokes"). S/F....Ken M

Doing a little research, pneumatic seems the way to go. You could use a mixed fuel, like gasoline, or acetylene/oxygen, but that would be more complex mechanically.

http://en.wikipedia.org/wiki/Holman_Projector
http://en.wikipedia.org/wiki/12_cm_Luftminenwerfer_M_16
http://en.wikipedia.org/wiki/26_cm_Minenwerfer_M_17

Thinking on it, larger projectile would probably make more sense, since you're not talking a weapon of maneuver, unelss you're going to mount it on a truck or something. And limited duration of the expected attack would mean that per shot effectiveness is more important than sustained fire or duration of suppression.

For the non-professional looter/pillager type, having a fire extinguisher or SCUBA bottle sized projectile full of flash powder land anywhere near would be incredibly demoralizing even if it did not create casualties. S/F....Ken M

The fuze was my thought as well, in regards to the fragmenting jacket and shrapnel producing munitions. It doesn't have to detonate on impact to be utilized.

Made a mortar with PKP Co2 cartridges on Rosey Roads.
Fun shooting them into the water.

For Grapeshot one could purchase a cannon.
My friend has one for reenactments.

Correction 3/4" nipple on the round.
5/16" holes drilled to act as venting.

The key is everything has to be dead center.
Tube can be from 18" and up.
