Reloading for the 217.49mm X 3785.41 cm3

[jmorris]

This one is for Jack,

Doesn’t really fit anywhere so I thought I would show off the lowest cost projectile launcher I have reloaded for.

I had a little time to play today waiting on a delivery, so I put together my 217.49mm X 3785.41 cm3, hauled it and a few hundred feet of air hose out of the garage to the “range“ and went through a few rounds. Using 40 gallons of air pressure launching a 16 lb (112,000 grain) bowling ball.

I didn’t have time to chronograph the load I used but even if it were only moving 1.5 FPS it would beat IDPA/USPSA “major” power factor making 168. If it were moving at a modest 50 FPS it would be making 5,600 PF.

The unique triple hollow point design makes it less than ideal for rabbit, squirrel and other small game due to unnecessary meat damage, maybe I’ll find an old foreign car or something.

You’ll have to click on the photos to play the videos.

Neat, i wonder whats your cost for a box of 50? Is it cheaper to go out and just buy the bullets instead?

You have entirely too much time on your hands. Have you ever thought of gardening... they say it's relaxing. :whistling:

They won't let him shoot Bowling Ball Pins. I am pretty sure they won't let him launch bowling balls either.

Sweet, how far did the 120psi go??

I got some bowling pins, the ideal target

I was wondering what the heck a 217.49mm X 3785.41 cm3 was.
I can barely afford to feed my AR.

Sweet, how far did the 120psi go??

90 yards or so at 70 deg. In the video you can see it impact out in the field in almost line of sight to the top right of the open gate, 6 seconds after firing.

Paper patching might increase your velocity! Try it a 55 degrees and you should get to 100+ yards! Try a ten pounder as well! I see great potential in this weapon as a deer gun!:supergrin::wavey::supergrin:

If a neighbor's dog poops on your lawn, you could stuff the crap in the holes of the bowlong ball and send it back.

[Palouse]

I thoroughly enjoyed that.

I hauled it out to the our last 3 gun match and afterwords it didn't take long for the guys to start working up pin loads.

That's way too big. I already had to put a QD fitting between the tank and barrel so I could move mine around.

The next step is to make it smaller and use black powder.
