If I remember right you had a 2 inch powder chamber.  Start with 2 oz and see what happens. then go to three.

Keep in mind that a smooth bore cannon 2 inch bore shooting a 16 oz projectile has a max load of 4 oz.

Trust me, shooting a bowling ball out sight is no where as much fun is shooting one 100 yards...watching it all the way down range and hearing the thump when it hits.  It's also a lot easier to walk down range and recover the ball to shoot again versus try to find the ball you launched out of sight!

MAN!!!

This thing is unbelievable.  About 220 yards with a 16 lb Brunswick with 2 ounces of Fg.  Same ball with 3 ounces of Fg is right at 400 yards.

I am hooked.  Sorry no pictures, my "photographer" was unable to make it.  

This mortar is awesome!!!  Shot over a pound of powder...  I will post pic's but am going to Colorado for an elk hunt first (will post them in a couple of weeks)...

Thank ya'll for all of your help getting this thing together.  Did I mention I was hooked?

I guess that makes us 'pushers'.

Great fun - and what did it cost?  18 to 25 bucks of powder and a buck or two for a yard-sale bowling ball?  All for the thrill of a lifetime!

But I can't immagine hunting elk with it.

Nope.  

$12 for a pound of powder (dealer getting rid of BP license).  
$0 for 3 bowling balls.  Called the bowling alley and asked for some useless old balls.

So total cost of $12 for the shooting, and about $40 for the mortar.

Didn't take much powder to move that ball a long ways did it!

I always cringe when I see the guy post things like  " the ball cleared a 2000 foot mountain behind the range!"  Who or what is on the other side of that mountain? At 45 degrees to have 2000 ft clearance at the top of the trajectory how far down range is that ball going...scarey!

I will be interested in seeing how far 1 oz takes you.

Hi Guys.  First post but I've been lurking for about a year now.  I'm Cutnroll's neighbor and the second guy on the left in the SoCal50s lineup.  We just got back from another desert outing of shooting, eating, and launching balls!  Boy was it a blast! (pun intended)  

We tried a couple of new tricks to add some excitement to our bowling balls.  For night shots, Cutnroll drilled out a hole in the ball and inserted part of a road flare.  We tried this a couple of times but only one lit.  I think the part with the striker needs to rest on top of the blackpowder.  We even tried sticking fuse inside the flare element but I think the striker is the key.  

For good tracking during the day, especially with those heavy charges, I drilled and inserted Estes model rocket engines.  The blackpowder charge has no problem igniting the engine as long as the nozzle is facing the bottom of the mortar.  The smoke trail is awesome!  The sound of the rocket covers the whisteling but still sounds great in itself and the little puff of smoke for the parachute ejection charge adds to the excitement.  One thing was interesting though.  We thought that the balls would spin alot and that we would see it with the smoke trail.  Not so.  With the rocket engines, the balls wouldn't spin at all.  I think the added thrust actually stableized the ball in flight keep the engine nozzle pointed downward as the ball flew away from us.  The larger the engine, the less it wobbled or spun.  

Well, that's it for now!  Let me say you guys have some neat stuff here.  Thanks, Mark

Yeah, but can you hit anything!

Some years ago  I saw some guys shooting cannons and mortars and they required everyone to bring 5 wooden pallets.  They wired four of the pallets into a square, then wired the fifth pallet on top. Most hits on the pallets won. Tie breaker was the most actual pallets broke. You might put rounds through the front and back with cannon or through roof with mortar but the sides were hard to hit.

That looked like a bunch of fun. Not only can you see the ball go down range , but you actually have to be able to hit something.

Let me tell you after you see a a ball hit a wooden pallet you understand why on the old wooden ships you stood a good chance of being impaled by flying splinters.  It was awesome!

Why don't you try something like that.

Besides shooting road flares and rocket motors sounds a little dicey to me.

Sydwaiz -

Welcome to the board!  I share the excitement with you of shootin' big bore.  Please keep up the stories and experiences.

DD is the voice of reason here.  It's good to have moderation in all the excitement.  I'm one of those folks who has learned by pushing the envelope and survived the experience coming away sometimes knowing that I'll NEVER do that again.  (I knew for years I'd never live to see 21.)

Seeing the 100 yard matches is a discipline in excitement.  But if you have a 200 or 1000 yard range that's cool too.

Again, WELCOME.  We'd love to see some pictures when you get a chance.

question? when you are building these bowling ball mortars out of CO2 or oxygen cylinder has anyone took a glance at the numbers on the tank? I guess what I want to know is 3AA2400 or 3AA2265. I relize that measuring them can tell you which one, but it would help me if I could ask for a cylinder # either in person or on the phone. I am currently having trouble finding one. but i have found a bunch of bowling balls.
Sorry I haven't posted in a while I have been busy training National Guard Artillerymen to go to IRAQ.

Mortars from CO2 tanks
« Reply #40 on: October 26, 2004, 11:08:24 AM »
Hi, I could wright a book about finding a CO2 tank. Here's the brief. I called some welding supply companies. They all said the same thing. Individuals can not own large high pressure tanks anymore. If you get one of their lease tanks, and cut it open. They will charge you with destruction of property. I found where tanks were being junked out. They have to cut the serial # off the tanks (this cuts out the part you need to make a mortar). They send this steel piece into the Fed's. The Fed's keep track of these tanks. They have been used to make bombs. I found an old tank at a farm auction, through a friend. Because of the Fed. angle. I don't advertise I have a tank. Even though I believe, it is one that is grandfathered in. It's serial # is no where near the #'s you posted. My advice. Keep looking. Talk to everybody about it. Someone has an old tank out there for you. When you find it. It will be worth the time. I've already be invited to bring my bowling ball mortar to 5 history festivals next year. The crowd loves it. Safety first.

Getting back to oxygen cylinders.  I was asked the other day what the number on the tank I used was as apparently there are several sizes out there.  Mine is 3AA2265.  The outside diameter is 29 1/8".  The wall thickness is 1/4".  Hopefully, this will help folks get the right size cylinder and not waste time on money on one that won't accept a bowling ball.

Best Wishes,  Bill Tyrrell

CO2 Tanks
« Reply #42 on: October 28, 2004, 07:26:32 AM »
My earlier post was a bit negative. It comes from all I went through to get a tank. It took a lot of time. But was worth it. Here is a bit more info for the people interested. If you find a tank the measures 29 inchs at the top. And 28 1/2 at the bottom. And you can get it cheap. You may want to try it. This is what mine measured. Most bowling balls will fit the 29 inch part of the tank. But not the 28 1/2 inch part. I've had 3 bowling balls out of 30 not fit, with proper windage. When they are hot from sitting in the sun. I just throw these bigger balls away. No point in taking a chance with them (they fit when cold). The smaller one's shoot great. Evidently bowling balls very in size. And definitely swell bigger when they get hot.

Safety tip: Check new bowling balls for proper windage, when they are hot from sitting in the sun.

I don't know how to attach pictures, but I do have some.  

A question I have:  Is it okay to shoot RS Pyrodex (FFg equivalent) out of my mortar?  I've been to Bass Pro, Cabelas, Gander Mountain and can't find a Fg equivalent of Pyrodex or Fg blackpowder.  The blackpowder dealer I was working with has sold all of his blackpowder and is out of the blackpowder business for good.  I am nearly out as well.  He says he doesn't know of another dealer of blackpowder anywhere in Georgia or even in Florida - - maybe in Atlanta, but that is nearly 4 hours away.[/img]

hey everyone, just wanting to move up to bowling balls. building a mortar now, how are you guys making the powder chamber? I was planning on using .25" thick  stainless pipe with 1" stainless welded breech. does this sound safe? I like the idea of O2 bottles (good friend owns welding shop) how do they work. Anyone want to send ideas please?
:eek:
