bigdoggy7002 bore black powder gun
Does anyone know of anyone that could build me a black powder 2 bore single shot rifle? I am looking for any info besides the stuff posted by 700 nitro and his 2 bore gun. Any info would be greatly appreciated. thanks

walksfarHere you go:
http://www.2-bore.com/I'm not sure if these are what you're looking for-they may be catridge guns. Still, it will be nice to see what info we can dig up about them.
As far as muzzleloaders only, I'm not sure.

GrandpasezI am slowly getting an action designed
to hold the 2 bore barrels I found.
Once designed I can build my own.
It will be cartridge, with 5" long 2bore
steel cases I built from 27mm aircraft
cannon rounds. Ed.

bigdoggy700walksfar, nice site but not much information on the site yet. Hopefully they will update with more info soon.Once they complete the video, rifles and a contact number, I am sure they will get plenty of business. Ed Huble, I was talking about shooting a 3500 grain round ball out of a 32" barrel with a gun total weight of appx. 23 lbs. Your 2 bore iway over the black powder size. That 2 bore cartridge of yours makes a 4 bore cartridge look down right PUNY!!!
17 June 2007, 21:10
GrandpasezYes my 2bore case would hold more powder,
even black, to get velocities you mention.
But I can use filler wads for lighter
loads. Advantage of longer case with
cushion wads is you won't have to resize
the bottom 3/4 of steel case, IE wads level
of the initial pressure spike. And room
for wads and big shot loads also.Like
18 50cal lead balls for a real buckshot
load is what I was planning for one of
barrels that I would make smoothbore.Ed

bigdoggy700Ed, I for got from a previous post, what will the weight be on your 2 bore project? thanks Ken
17 June 2007, 22:55
GrandpasezKen - I plan on about 30-35 lbs.
It could be as light as 23-25,
but recoil would get up there.Ed

surely not a 10 lbs 2 bore!!!! I think youre gonna need some extra weight for this one!

Marc_StokeldIf you look at the "Recoil" page on the 2 bore site lined to above, it shows a 25# gun recoiling with
545 FT/LBS!!!. Good God man, you can kill a deer with that amount of energy.
Do you think it would damage the 3 plates and 10 screws holding my neck in a stabilized position?
I am going to say soemthing I have VERY rarely said to others, but other have told me on a regular basis since I was old enough to walk:

ClaymanI don't know how this one's gonna work. That's a tremendous amount of energy on both ends, and I just can't see that being practically fired from a shoulder weapon.
Either way, I don't want to be on the receiving end of 545ft/lbs of energy - ever.

The MetalsmithOne of these may be the only solution to Safarikid's masochistic recoil addiction!
I gotta wonder what the actual rifles do look like. I'm amazed at such a feat of engineering, although I won't ever own anyone I would be envious of anyone who's actually shot one!
Now I wonder if they could spin up a 4,000 grain conical?

And almost 18,000 ft-lbs of energy at the muzzle.
I haven't seen many things on this site that I didn' think would be fun to try, but I think I can unequivocally say that I don't see myself pulling the trigger on a 25lb rifle shooting a 3500grain bullet at 1500fps.
That's gotta leave a mark.

trophyhunter5000You would have to use 4000 grain bullets in order to get the SD up above .300....

All kidding aside I wonder how well one of these things would penetrate? I assume it would have to be impressive..........

Bill/OregonI think I would prefer to step up to a small Krupp Mountain Gun, and rely on my .577 3-inch Greener for the small stuff.

GrandpasezI plan on first one,when I get action to put
barrels on, to be smoothbore. That way I can work up
using 50cal lead balls for overgrown buckshot loads.
Start out with 12, then 15, then 18,etc.And
because they have large primers I can use slow
smokeless powder. Less cleaning needed.Ed

Hog KillerI have used 72, .50cal RB for a canister load for this BABY. That is over 1 1/2 lbs of shot.
Of course I am bright enough to put some wheels under it.
Solid projectile weighs 1lb 12oz.(12,250gr)
Powder charge is 2 1/2oz BP (1094gr)

bigdoggy700I would think that shooting a 3500 grain ball at 11 or 1200 ft/sec would not be too bad. I don't know about 1500ft/sec. I would definatly have to work up to the recoil after about 200 to 225 ft.lbs of recoil. Max loads at 545 ft.lbs of felt recoil seem damn severe to me, and I shoot alot of big stuff.

MacifejRecoil calculations at
www.2-Bore.com are stated as "Formulaic Calculations Only".
I would like to meet the Gigantopithecus who could handle 545 pounds of recoil without serious injury! The true net felt recoil of this rifle is somewhere in the neighborhood of a 10 pound Weatherby .460!
21 June 2007, 19:00
The MetalsmithUmmm....maybe this is just the hangover speaking but as for a "overall felt recoil," I truely believe this 2-bore would make a .460WM feel delightful in the recoil department, moreso in it's 25-pound guise.
It's a awesome idea for those truely nuts enough to use one. If I were to buy one, I think I'd be buying a good carriage to mount it onto.

Ed, what is the caliber and twist rate of that barrel? Looks pretty fast.

Jim Manion545 ft pounds of recoil. An orthopedic surgeon's dream!
Maybe some of those out there in the medical community can address how many foot pounds it takes to break a collar bone or dislocate a shoulder. And how about the whiplash to your neck?
I never thought of myself as particularly recoil sensitive, but those recoil numbers are INSANE!!!

bigdoggy700Those recoil numbers are at the high end. You could certainly start off with a 3500 grain ball at 1000-1200 ft/sec. While recoil is still alot, it would not be anywhere near 545 ft.lbs. I know my 13.6 lb 600 overkill can deliver about 190-200 ft.lbs of recoil, and that feels like alot to me, though it is doable with practice.
24 June 2007, 11:36
MacifejDon't forget about the 3 pounds of steel and bronze hydraulic damper in the buttstock. This is a custom engineered piece calibrated for this rifle which takes the RRRRRRRRR out of recoil!! Then there is the soda can sized break on Dumbo's muzzle! Still working on how to keep from starting brush fires when used. Overall I suspect that most will find it like being hit with a slow moving heavy bag.....unless you're on the hot end.
24 June 2007, 20:51
GrandpasezRIP- That 30mm barrel is 1.225 groove dia.
About 1 to 15 twist for heavy 30mm military
projectiles. For 2bore I'm going to take out
rifling on first one for a smoothbore,
that gets 1.225". If I do one rifled I'd
shallow up rifling as it is twice too deep
for what is needed for 2bore use.Ed

Omnivorous_BobEd, just keep in mind with that barrel that according to the Greenhill formula you'll have to limit you bullet length to 15 inches or less!

GrandpasezAt 15", a brass slug would be about 5 lb slug.
Lead about a 7 lb slug. I don't think we will shoot
anything that heavy. Might work up to 24 lead
50 cal balls in smoothbore. By the way the reason
I would like everyone to use these barrels or
others bored to these specs(1.225") is to get
a standard, and easier supply of barrels
for everyone. Getting real big bore barrels
is a pain.And these are already out there. Ed

25 June 2007, 06:06
MacifejIf you're going to do smooth bores then it makes MUCH more sense to buy bored and reamed blanks from a deep hole drilling specialist. Cheaper, faster, and better than barrel making sources or buying surplus cannon barrels. Then have it profiled and polished at your local CNC shop or do it yourself. No limits on sizes or material either. FYI - Greenhill doesn't pencil with GAU-8, M102, 35 Oerlikon or anything else that combines high weight and high velocity. (Build the equation and check against known configurations.) The twist rates for those barrels are useless for shoulder fired weapons. UNLESS!!! you want to make an skid mounted sniper cannon! Already been there. Takes an 80 to 120 pound platform to reliably launch an M102 size round. BE VERY careful of the shockwave with the muzzle so close to your head!!
