Just wanted Tom to know he's all over the net...

Looks like about as much fun as 5 minutes in the cage with Brock Lesnar!!!

Impressive, but I would be more impressed if one were to make a video for the world to see where he fired two shots and actually hit some water jugs or blew two or four holes threw something.

What do all these one shot videos prove. Looks like a stunt.

fourbore, SAFARIKID has posted pictures of Cape Buffalo detailing the entry and exit holes from his 4-bore double. Very impressive.

BE CIVIL.

Yup, Safarikid actually hunts with his toys. The video does demonstrate the recoil that monster generates!

Autograph's anyone? I'm Famous! Thanks GS!

I take it that is a nitro load he is shooting in the 4 bore?

Gee Fourbore....See you apparently have a 4 bore yourself(hence your name here?!),Why dont YOU post some pics of blowing up jugs or melons or something please. We ALL would love to see YOU in action sir!
As far as it being a "Stunt",in which way I humbly ask
And while we all anxiously await for YOUR pics,videos and perhaps "stunts",I will add another video of me blasting 2 cartridges in sucsession for my latest Stunt!(one day,maybe both at once)
http://www.youtube.com/watch?v=W7lhTqWOS5Y
And Yes,I have taken it to Tanzania(that is in Africa) twice and have Harvested 2 Buff with it

We use Blue Dot,Not black powder...

Just how much blue dot is used (not familiar with the Blue dot to BP conversion).

OH BOY!! fourbore, you are new here, SAFARIKID shoots and hunts with a 5 pound 458 Lott and an 8 pound 600 OK.

Tom:
We've got to get together one day. You like big bores, you like expanding bullets, and, you actually go out and shoot animals with your big bores.

You use the blue dot for consistent combustion of another powder, right?

Have you come up with an expanding bullet for the 4 bore?

Yes,we "deaux" need to pop a few caps together!...I do hunt with all of them when I can,but had to slow it down till I get my "Change" from our ever so giving new Prez!
My 4 bore builder,Ken Owen has done alot of testing and likes Blue Dot best,with lots of filler.I can't remember exactly what load,but I recall around 130 grains of it.He also had a company make 2000gr True Solids and 2000 gr Bonded Lead/copper Softs for it.
Maybe one day Mac will have the 2 bore single rolling and by then,I hope to get one too...Now we are talking 3500grains at 1400fps with a Huge 1.5" hole Lookout Hogzilla,I'm a Coming for ya!

An apology often goes a long way - of course one would have to take his foot out of his mouth first. We've all been there...

No apology needed here...We "Stunt Shooters" are used to it

I just watch the second video. two shots! Was that just for me?

Only way i ever own a four bore is if I learn how to machine one. Not likely. Just another dream.

I should probably apologize for remarks, but the two shots video was worth it. I just say thanks for the 2nd video.

No Problemo Senoir' But,I Must ask,Why "Fourbore" as your handle here??

I found this forum and thought hey "fourbore". I should really appreciate those video, because it like a life long dream. And yours is a traditional gun. No brake or porting.

Back in those days, 1970's, I walked away from a Holland and Holland cased 4 bore. I believe it was $10k and about $9.5k more than I could muster up in those days. I never forgot the gun. The four bore always seemed the ultimate big gun to me. Not necessarily practical, but ultimate.

I owned a 6 bore muzzle loader at one time. My 6 bore was a smooth bore ball gun from Dixie Guns works. basically a cheep POS but a lot of fun for wet behind the ear teenager. I managed to knock by self back on my a$$ one time. And came close a few more.

I used to read about these guns and some experts or authors claimed the best killers back in the day were 6 bores with connical bullets and a heavy charge. Seems the 4 bores fired round balls did not penetrate as well or enough to justify the recoil and weight. My a$$ starts to twitch when I hear some complaints that such and such gun is only measures out to a six and not a true four.

pardon the ramble....

Now I understand....The modern bullets we use in ours enable it to be used to its full potential and Destroy whatever is in its path!Mine was a True 4 bore,over 1" bore. I also had a 7 bore WW Greener,a 8 Bore Tolley....They were fun too!
I hope you eventually get your dream gun!

I felt the same way you did, "Ouch", after I shot a 600 grain 2150 fps, .510 Van Horn. I can't help but think Rob has found the Holy Grail of big bores, in that the huge case capacity means a much more effective use of a muzzle brake.

Course Tom figured that out, too.

Oh,By the way,it is for sale now! Check out the gun and its engraving,DEEP Relief at that!Took over 300 hrs to do from a Master!Bruce Bradshaw...Click on the pics to blow them up!There are many volcanoes,period foliage,dinosaurs of all types,some even with animal body parts in there mouths!Mastodons,T-Rex,Lizards,Sabertooths,etc.Please notice the "balls" of the action(rear section where barrel meet face)Both balls are Open Mouth Sabertooth Heads! A work of art for a mere 100k fellas!

The actual load for the 4 bore Ken Owen rifles is between 112 and 116 grains of blue dot. It pushes a 2000 grain bullet out at around 1460 to 11490 ft/sec.

Any idea why that works, and doesn't create incredibly high pressures?

A 115 gr of Blue Dot isn't very much powder
with an expansion ratio that big, with that
relatively light slug for the caliber. And it is
one of the slower shotgun powders.
You couldn't use that much bullseye for example.
The powder column length inside the case
is only fraction of the case length, the rest being slug
and wads, no airspace, so the expansion ratio is
about 30 to 1 which is 3 times what most straight cased
rifle cases run. It would take 150 gr to get top magnum
shotgun pressures like I use in my NEF with 12GA FH,
with a brass case.Ed

If I ever touch off anything that big, I'd want it on a wheeled carriage. My hat is off to you.

A 2000 grain 1" bullet has an SD of .285, better than a 180 grain 30 cal bullet which is only .27. Anything over 100 grains is a LOT of powder when shot from the shoulder. It's all relative!

Hey Man!
Is that at Lewis Drake's place now?
If so I am making a run to go ogle it in person.
Price on that web page said $115K.
That will break the piggy bank!
What's with the knots in the butt?
They are tiny, but there are several.

Granted 4bore 2000gr slug has a fair sectional density, but if
the shape or proportions of the slug, made up diameter and "length", was
same as a 30 cal 180gr then it would be 3 times 2000 gr..
A 30cal roundnose slug is 3 times as long as its diameter where the
2000gr 4bore slugs I have here are nearly the same length as
their diameter. That is why it is light for the caliber, proportion
wise,in comparison. Now of course you couldn't fire 6000gr
or about a pound, slugs at 1500 from the shoulder. In a way I will
be happy to have our 4bore with smooth barrel, so I can shoot lighter
hollowbase slugs. Even if fired faster enough to get same energy
as 2000gr the recoil is less. ED

Hmmm...

A 1" conical flat nose bullet is like a pre expanded 600

I wonder how much a 3" aluminium flat nose solid would weigh.

Ed... Got any 1" aluminium bar stock?

Ed, you make good points.

Lots of folks get wrapped up in SD numbers, and declare anything below a certain number useless for hunting. I think they miss the point. Most .270 or 25-06 bullets have a rather low SD, while even the humble round ball exceeds the magical .3 when you get a bit over 2-bore simply because mass varies with the cube of diameter and SD with the square.

I think hollow base slugs are an interesting idea. I would think a smooth bore would offer more velocity for a given pressure (but less pressure for a given powder charge). As you mentioned, you have plenty of room in the case for wads to ensure a good seal.

I know guns this big are usually thought of as a short range arm, but think the idea of a streamlined AL slug is interesting, perhaps with a lead core for balance. Sort of a giant LT capped paradox round. I also think the experiments with bullets having a pronounced forward CG in the 12GFH some are doing here are quite interesting. A fin-stabilized smooth bore 1" long range round would be cool, and a great excuse to tinker in the machine shop.

Keep up the good work!

Bob

I think the aluminum slugs with a forward CG
are an idea for 4bore that is worth looking at,
and also casting a Lyman style, shuttlecock
style slug, like used in 12ga, just scaled up
A 2" long aluminum slug with hollowbase
would be about 900gr. A Lyman style in lead
about 1800gr. Lynn Hull who makes the jkt 4bore
slugs, also makes swaged lead ones with a slight
hollow base.I gonna get some of them coming.
Just deepen the hollow until slugs
shoot stable.Ed

Awesome Ed!
That would be throwing around some serious aluminium!!!
And cheap too!
A Macifej design aluminiun 900 grain conical flat nose @ 2700 fps would be quite interesting!
Shoot some DWG's and trees with those =)
I guess you want a forward CG because of no twist on that smooth bore of yours.
Should be fun!
