I've been researching some stuff for a "rifle" project.  Seeing as how DD's adventures with the .416 have had some close calls with the much hated crat, I decided something more potent was called for. 4 BORE. That's right. Inspired by the lunacy of fellow AR members Ed Hubel, and Rob Garrick, I've decided there's only on approriate stopper for the much hated Felinus Domesticus, and it has a .950 groove diameter.  First, the Barrel - this is the easy part - Krieger makes them - gonna be a 2" diameter straight tube as long as they'll make it. I am going to have to machine a custom muzzle brake, as nobody makes one that big. The action is going to be basically a scaled down version of an Artillery dropping block. I'm still undecided as to the stock - should I make this a return to battery rail gun, or go for the outrageous and make it a mini towed arty?  Ammunition proved to be the headache, specifically brass. I've got two leads, and I'm going to pursue both in the next week or two. Bullets are going to be cast, from a 3500grain mold from NEI. That's 8 ounces folks! I plan on shooting hefty loads of 870 surplus powder, it should lob that big hunka lead close to 1600FPS. That works out to be in the neighborhood of 20K ft/lbs. of Muzzle Energy. Wanna know the best part? It has a DD exemption. I think it should serve as a stopper for crats.  HTRN  | ||

I have one of those 3500 gr cast bullets laying around . I did some trading with a guy from another Forum and he sent me one as a teaser . IMO you should just have enough energy to do the job right  I am building a 50/460 , but that will be a pipsquike compaired to your toy .

HTRN, Go for the towed arty set up. No break will be needed then. Also no wood working. Set it up with an automatic breech that opens at full recoil position. That way you just need to throw in another round and close the breech. I would also suggest water quinched wheel weight lead for your projos, hard, cheap and plentifull. Keep us posted on your design, I like the scaled down arty idea. May need one myself, as I do not have a breech loading cannon.

I dunno, Ed Hubel is building a 2 bore on surplus 30mm barrels.
The hard part is going to be getting this past NYC firearms control. I don't see a problem with the BATFE, as it's an existing design, but oddball stuff, in large calibers would set off alarm bells in Queens Borough Hall. I may make everything BUT the receiver, until I can get the feck out of here. I'm familiar with casting - I have something like 20 Magma molds waiting for me to come up with the scratch for a Master Caster. I'm also an occasional poster on the Castboolits board. Waterdropping makes wheel weights HARD. Like 27 Brinnell. I may not be able to size them manually. As it is, I'm going to have to build some kind of sizing machine, as I can't even make a die to go into a regular press, the boolit is just too damn big. What I may try is to dip in some lube, and then press them through a sizing block using a 50 ton hydraulic press. Wood was never an option. The action simply wouldn't permit it. Arty falling blocks are open at the back. I was talking a RAIL gun. If you ever seen unlimited class BR, you'll know what I'm talking about. As it stands, I am going to rip off one concept from them no matter which version I do: mounting is going to be a barrel clamp, or some variation thereof. HTRN | |||

Nothing but cast lead. Shooting nasty stuff is a nice way of getting the Boys in Black Suits after you.
Considering that I plan on using loads approxmately DOUBLE in terms of energy of what's considered "prudent" in conventional 4 bore rifles, I think not. I may be crazy, but I'm not stupid. HTRN | |||

Here is a pic of the bullet you are going to use I think . It is 2.22 " long . The loaded round is a 44 mag for compairson .  Johnch NRA life Delta Pheasants Forever DU Hunt as if your life depended on your results | |||

Yup, that's the one. Hell, I don't even need the gun to kill a crat with it, just throw at it! You wouldn't happen to still be in touch with the guy who gave it to you, perchance? I'd like to hear how he's sizing them. And for the edification of the hard to impress:   Heeheehee. I almost wish Birman and his flunky were still here.  HTRN | |||

HTRN, Great looking round. I would not worry about sizing those bullets. As long as they are no more than .002-.004" over bore size, I would just shoot them. Lube them by hand, just smear the lube on and seat them. Go ahead with the action and mount, and leave the barrel off till you get "Out of Dodge", so to speak. This project would also be neat in 50BMG. Easy to feed, HV, scoped, long range crat blaster.

I may very well have to use a muzzle brake, to keep the thing from moving, but I'd rather not as cast lead bullets and brakes do not get along on the best of terms.
The bullet is nominally .005 over as cast, but if I think the alloy used for measurement is higher in Antimony than wheel weights, and probably shrinks less. Making the action without a greenform is a serious nono. It's legally considered a firearm, even without a barrel. Even Muzzleloaders require a permit here. Personally, I think this is an awful lot of work for a .50 - it's expensive and time consuming. for something you can buy for $2k in a singleshot bolt action. I'm not going to give/sell plans, blueprints, etc, but I do plan to document the build once the money starts flowing and the chips start flying. Any competent machinist will be able to duplicate the general design. HTRN | |||

If you had gone with a standard 20MM brass would have been relatively easy to come by!  derfQuando Omni Flunkus Moritati | |||

If I had gone with Standard 20mm, I would have needed a Destructive device permit. Something that is simply not possible here. BTW, PacNor sells 20mm barrels. I also know where to get 40mm barrels. HTRN | |||

What do you use for a gas check? The bottom half of a beer can? Also, if you go for end to end shots that should clean all nine lives out of them at once. | |||
|
| one of us |
I DETEST gaschecks. There too damn much work, and it's something else to buy. Big slow moving stuff like this doesn't have any checks,(In fact, I only have one mold that's a gas check design, and it's going to be reamed out to a plain base). HTRN | |||

It's kind of wierd how the laws work in our respective countries. Up here a 50cal Barrett is restricted or prohibited but we can have an M79 and it isn't even considered a firearm because of it's low velocity. Go figure! derfQuando Omni Flunkus Moritati | |||

A Destructive Device is any firearm over .50 caliber with "Sporting use" exceptions. Basically, if it's over .50 and can shoot Military Ammo, you need a DD permit. The 4 bore has such an exception, it's an ooollllddd cartridge, originally loaded with black powder. Searcy actually makes a 4 bore double. HTRN | |||

But yet you can go and buy a full size replica black powder cannon,,or build a bowling ball mortar,,with no paperwork at all? Clay | |||

No cartridges. If it's non fixed ammunition, it isn't considered a firearm(at least not as far as the Fed.gov is concerned). Also, any gun made before 1898 isn't considered a firearm. HTRN | |||

Dumb Canadian laws thought up by dumb Canadian politicians and bureaucrats. Flintlock rifles don't have to be registered, and don't require a permit to buy, because they are "antique firearms" - even brand new ones. Flintlock handguns have to be registered and you have to have a restricted firearms (handgun) permit to have them (apparently, they AREN'T antiques - even real antique ones). However, percussion rifles have to be registered. Percussion handguns require registration and a handgun permit.  Virtually identical technology, the only difference being the source of ignition.Cannons/mortars are considered "antique firearms" and don't require registration or a permit. I've seen a Pedersoli .69 cal mini-cannon. Unregistered, unrestricted, uncontrolled. I could take the barrel off and stick it in my coat and walk down the busiest street in Toronto, loaded, with a fuse in the hole and a match in my pocket, and I would not technically be breaking any FIREARMS law (though I'm sure the cops would find SOMETHING to charge me with). If I took the barrel off my single shot percussion or flintlock pistol, and carried it completely empty, I would be charged with carrying a concealed weapon, illegal transport of a restricted weapon, weapons dangerous, and anything else they could think to throw at me. | |||

That cabinet is mostly empty, where's the rest that go in there? That big cartridge looks more like a dildo to me. hehe! Hell of a slug, I like the design.

It's one of two, plus the safe, plus whatever is stuffed in the various nooks and crannies around the house. Dixie's cannon stuff is mostly muzzleloading blackpowder. HTRN | |||
