Lewis and Clark used an air rifle to bring down game.

That was a long time ago and technology has increased a lot.

For the ultimate $5,000 .87 caliber beast: Untitled Document

I build inexpensive, less than $100 air rifles from parts available at Home Depot.

Posted on DC here:

Powerful Homemade .785 caliber Copper Rifle

They can't take copper tubing, valves, and nails away.

Check this out as a cheap semi-auto air rifle.

It is PVC and 200 psi, but it could be steel at 3,000 psi and be very lethal.

A manual auto shock pump could be used. (no electricity)

Crosman Introduces New Benjamin Turbo Aire 3000 PSI Hand Pump

Crosman Corporation, long known for innovation and quality in products for the shooting sports, has introduced a new, patented Benjamin® high pressure hand pump. The new Benjamin Turbo Aire™ provides up to 3000 pounds per square inch (psi) and is ideal for pre-charged pneumatic (PCP) airguns.

Professional hunter Jim Shockey comments, “Charging my Benjamin PCP airguns with the new Benjamin Turbo Aire hand pump gives me the flexibility and freedom to pursue game without needing a filling station or a bulky scuba tank. Convenient to use and powerful enough for a 3000 psi charge, the Turbo Aire is going with me on all my airgun hunts,” he said.

Pressurizing PVC piping with compressed air is extremely dangerous...the PVC piping/joints could rupture and projectiles of sharp pieces of shattered PVC could be sent flying in any direction and this could kill or seriously injure someone.

Yes, you are correct, if you pressurize PVC beyond 200 psi it could explode.

Type L Copper tubing is OK up to about 1,000 psi.

Hand guns easily handle 30,000 psi.

Rifles go to 50,000 psi and beyond.

Why not just use a paintball marker? They're widely available and easy to use. I have rubber training balls my team used to use for practice when I was playing tournaments and they're reuseable and inexpensive. Crank up the velocity and those rubber balls might not kill but a string of em flying at someone's face at five or six hundred feet per second will hurt enough to make them wish they were dead. Heck I've been tagged in the throat with one at normal velocities and it'll take the wind right out of you. If the laws changed tomorrow and God forbid all guns and ammo were banned, I'd keep one loaded up with rubber balls or pepper balls for home defense in a heartbeat. Better than nothing I suppose.

Time to Learn how to make spears.

Seriously, it pays to have some kind of fall back system in place if there is no ammo around.

That is pretty doggone cool. Absolutely it has cool factor.

I'd probably opt for a powerful crossbow with broadhead bolts though if the SHTF and there was no gunpowder or bullets available.

A phillips head screwdriver is a great weapon. Also one of those T-grip tools that are in auto tire plug kits.....
