I have some ideas for Fort Pallet II, I have been offered some bricks.

I didn't hit the fort with my mortars and there is a lesson there. Day one will be used to find which mortar is shooting best and the best shooting mortar will be used for the attack on the fort. Problem was I was to busy trying to shoot all the guns to have shot any one well. I think the pop can size zinc ball will do the job, but its a bit tough golf ball mortars.

I did find some hits from my 1 inch gun on Fort Pallet when I took it down.

The balls penetrated one layer of the pallets and fell out on the ground when I took the pallets down

Rocklock 1,
I need a shooting lesson. I don't think I can get mine to do what yours has done.

Let the arms race begin.

Before we get too far along on this arms race...keep this in mind.

The Cut Bank Cannon Convention is for 1/2 scale and smaller cannon and bowling ball MORTARS ONLYwhich replicate pre 1899 designs. If you are building something to take on Fort Pallet the gun will have to meet that criteria....

This is my new 'on paper' fort crusher it is a 6pder half scale of a 12 lber

Shown actual size with powder can .

It is as small as I can make it , so it does not break the entire defense budget . I will/may make a heavy wooden base for it .

DD what is the dia. of your 6 lb ball mold . Like Zulu said you want to know the dia of the ammo you intend to use

. Also what is your load for the Junkyard Dog

Found a few more clips and pics of the Montana Shoot.

We arrived at the famous "Gofer Ranch" early Friday morning. Seacoast's Krupp Howitzer is all bound up for protection during the trip. Old habits are hard to break!

This is Aaron's steel GB gun and handling recoil is what is most noticeable about it!

Making a powder charge alignment guide for Aaron's chambered cannon.

Cory did a fine job with hacksawing sprues off all the cannon balls we cast.

Casting some molten zinc into the pop can size mold.

Mike drops a hot one into the water bucket; I put 5" of dirt in the bottom to save the plastic!

The 7" Brooke gets sighted in at 40 yards.

While checking out the hole we spotted a virgin bullseye on a 100 yard target.

I think we are sighted in at 100. That's a keeper.

Do the balls go out of the mould into the water right away after casting?

No, they are given approximately one minute to solidify before the plunge. You don't want to reach right in there to grab them either!!

The water probably isn't hot enough to boil lobsters, eh?

Here are some videos from the shoot !

"AH ,We're close dad"

"I forgot to aim !"

damn it

Here is the third of 4 very good shots ,Mike actualy had a clover leaf at 50 yds. He shot my VOC gun . Also from @6-8 secs you can see the 150 yd red milk jug ,the sun is hitting it just right . It looks like a white speck on on the hill the far right of the frame ,at 7 secs. another round landed to the right of the jug. It is just to the right of the telephone pole
I blew it up with a fox ball !

Here is one of the Mighty Brooks ! It shoots ,passes thru the fort and hit the backstop .

"Do it "

What a hoot!

Any one who was there will tell you the whole shoot was a Hoot !

Thanks DD for the organization , implementation , And hosting the Shoot and Barbeque afterwards .
A very satisfying week end for all .

Douglas, I beg to disagree with your assumption that a member of GBO has pounded dents into your mold. After noticing that the mould halves no longer fit together properly, I asked for a file and was handed a very well used lined burnishing tool that may have at one time been a file. As I was carefully hand fitting the mold halves back together with the tool that you supplied me, I noticed that the surface around the sprue area had been thoroughly struck with what I took to be a ball peen hammer. I believe that the Roto metals crew may have been in a rush to produce your bucket o balls and get the money. Anyway, I don't believe that the dinky brass tapper in question could have possible dinged up your mold unless it was used like a framing hammer. I believe that the fellows at Roto were in a hurry and forcefully ejected the balls with a 48 oz. hammer otherwise known as a 3 pound Maul.

Regards,

Mike

That file has only been in use for 20 or so years and was like new...and even a brass hammer will mark a hot steel mould...and believe me the Roto metals crew will be getting blast also...no mercy for anyone in this

Curious enough to ask... being the shoot is limited to 1/2 scale and under plus bowling ball mortars... I have two projects that are 2/3 scale on the exterior dimensions but 1/2 scale or less for the bores. Would they be allowed to "compete" at this event?

When casting, I usually use a large pair of pliers to grab to lip of the cone leading into the sprue to pull the casting out of the mold half it doesn't stick in... if the cooling cycle (no. of seconds before splitting the mold halves) is adequate to solidify, the shrinkage is usually sufficient to allow a clean release from the second half without any pounding... my grandkids dropped my mold a time or two... that is/was my problem.

If someone drives 300-400 miles to shoot in our shoot, dragging a 2/3 scale 1/2 scale bore cannon we are not going to turn them away. You will be allowed to shoot all you want on load development day. You will be allowed to shoot the structured events where your gun is appropriate. FWIW, I am considering restricting the SAMCC big bore to less than 2 inches and perhaps smaller than 1/3 scale. You would not be allowed to shoot Fort Pallet.

Our range is not really big enough for big guns. We have 200 yards. There plenty of venues for the big guns. The venues for our little guns is limited. I am reluctant to even allow the bowling ball mortars. Our shoot is not about gamesmanship it is about having a good time learning how to shoot our little guns in the spirit of the original.

I am aware of a papered bowling ball howitzer that might show up at our match...I don't have any structured events it could shoot in. Now should we start seeing these guns show up, then I might consider creating an event for them and restricting them from others, but it would only be one event. I want to keep this shoot for the little guns. Be honest, don't you think if a bunch big guns started showing up they would over shadow the little guns real fast...

We all could build rifle bored 1/2 scale or smaller muzzle loading cannons with scope mounts and level Fort Pallet in minutes....that isn't what this shoot is about.

Our shoot is for the small guns shot in the style of the original. Our friend Rocklock clearly demonstrates busting waterjugs at 200 yardswith his smooth bore golf ball Parrot-gun that shooting accurately in the original manner is achievable--

Hmm... so a 40mm rifled Whitworth is in? Smaller diameter then a golf ball

But , But , They are such crowd pleasers .

And mine is not so accurate as to spoil the fun for the other Fort Shooters .

Next meet I would love to have a huge tub of water as a target for the mortars . Perhaps a dug hole with plastic liner with 1000 gallons or so of water .
I think it would make a big splash with the spectators

You could shoot water ballons!

OR at a stack of water baloons.

I said a huge one . Perhaps more like a 3 acre pond like in front of my house

Edit : Perhaps a Moat in front of the Fort , Would be a great visual effect when a mortar round fell short and would prevent "Roll Ins "

How about shooting a car at 200 yards...

gunsonwheels · « **Reply #326 on:** September 01, 2011, 06:26:37 PM »

Cars are good... there was someone dumped one out by the hill we used to shoot into and it made a great target for shooting with 40mm rifled cannon. I have a slug went clear through it... front to back. I'll post a pic of it tomorrow.

GGaskill · « **Reply #327 on:** September 01, 2011, 09:33:33 PM »

Someone somewhere I can't find right now (turns out to be here) posted a question regarding what was a "bolt" as referred to in many posts regarding the Seacoast Brooke Rifle. A "bolt" in this context is an elongated semi-cylindrical shot as fired from this piece although this one seems to be more of a wadcutter. But as a picture is worth a thousand words, here are a couple. This bolt was recovered from the battle field surrounding Fort Pallet and it was decided that it had hit something sideways to cause the damaged skirt.
