4 Bore rifles in Australia
      #168239 - 22/09/10 11:12 PM

Does anybody know someone in Australia or maybe overseas that owns,shoots or has used a 4 bore rifle,particularly a single shot ?
I have a friend who is interested in aquireing one but wants to do some research on them first..

I have made a few.

I know one man hunting buffalo "down under" with one I made, but I have only a few details on the hunt. He used to live in Pennsylvania, but I understand he's moved now.

He did tell me it was far and away, the best killer he's ever shot, but at 1.052" diameter balls, (1750 grains)I was not surprised at that.

I'd be happy to answer any questions he has if I can.

They used to paper patch the projectiles for the 4 bore express rifles to minimise lead buildup in the rifling. I think the projectiles were conical and weighed 1500 grains, so there there was a reasonable amount of paper patching involved.

Contact Len Steele at Ammunition and Armoury Services (Melbourne) He was involved with the cartridge manufacture (I think he turned the cases and cast the proj) for the Rewa 4 bore that appeared in a SSAA magazine about 10 years ago. Might be of help.

I like them with 2 barrels as in a double.

I think the second barrel would really be redundant

...besides you need to have at least one retina still attached to fire off an aimed second shot

A true 4 bore round ball weighs 1/4 pound, which is 1,750gr. (7,000gr. divided by 4) & is 1.052" in diameter.

If 1,500gr. is correct for it's projectile, why? The reduction in weight must come at the expense of a hollow projectile which would penetrate less in comparrison to a solid round ball as the lighter, hollow bullet has lower sectional density, or if the gun has a much smaller, non-4 bore, bore size?

A 1,500gr. round ball is well under 1" in diameter - about .985", where as 4 bore is 1.052". What is the actual diameter of a 'solid' 1,500gr. slug - would it be closer to 7 or maybe 6 bore? Either would make more sense.

See mauser- just saved your retinas with a little 6 bore.

Ahh, that's much better. Dealing with loose teeth fillings is much easier

Actually, I fired a friends 505 Gibbs a couple of weeks ago and that flared up my sinus' (I was only an inch away from getting a headache anyway before I fired it). The following 5 shots didn't make it any worse though.

How much does that single at Century Arms weigh? I remember reading a piece on shoothing that monster. I seem to recall a 4" case and conical projectile. Dangerous Dave at Old Western Scrounger imported a bunch of the ammunition for that project and was selling them as curios. Anyway, the author was describing a bright "flash" everytime he fired it. He initially thought it was muzzle flash, but discovered it was actually his retna separating from the back of his eye under recoil...

I can handle recoil, but load it sensibly with roundballs (OR add wheels and a string) and I'll fire it.

That's scary. I always joke about retached retinas and was skeptical that it could happen from firearm firing - I have always assumed worst case that you would break a shoulder or lose consciousness if you fired something too big (like a 50BMG bolt action without the muzzle brake), but firing the 505 Gibbs did feel to me like I'd been punched in the head.

The century arms 4 bore weighs 22 lbs. There are not many true 4 bores out there at a true 1.052 diameter. A lot of the old English 4 bores are really closer to a 5 or 6 bore and most have a diameter in the .980 to .990 range. The old 2 bores were really a true 4 bore back in the day. They are not practical, but you can learn to shoot them without them feeling like a punch in the head. With practice, proper fit and stock design, they are shootable. Most kick far less than a 700 nitro at 16 to 17 lbs. But they are not for everyone.

As my moniker would suggest I have an interest in the 4 bore rifles. I had a true 6 bore that was smooth bore round ball gun. Although limited in this in my practical experience, Ive done a lot of looking and fair amount of reading. And sadly maybe forgetting too.

I consider the "TRUE" four bores to be any guns that fired 1/4 oz projectile. Thats today. But we used to call them 5 or 6 and no shame or denigration implied. In most cases just the opposite. I guess the commercial reality had lead to referring too all the over 8's as being 4 bore.

And in my opinion (and just an opinion) the 'best of the best' so-called (today) 4bore were all proofed as 5 or 6 and fired conical ~1/4 ounce bullets behind the heaviest charges of black power. And for the few who could handle them they were the best killers, prior to cordite.

All the 1 inch guns I ever saw or read about fired 1/4 ounce round balls and were the biggest (bore diameter) guns actually used with any success and built in any numbers in excess or 1-zee or 2-zee experiments. I hear a few guns were made to fire 1 inch conical bullets but yet to see in person or even a photograph a single example. I hear there was a new book, I need to find a copy.

I suspect 150 years ago as today we had odd ball exceptions and experiments. Wierd stuff happens, like terminator II fantasy weapons. Someone today or yesterday build this or that but the guns were really hunted and called four bore, were generally proofed as 5 or 6 and those were the great guns of yesterday. Those and the round ball 4-bores the biggest bore, if not the best.

Thats my take on the past, and what happens in modern time is a separate subject. Anyway was not just 4 and 8, it is 4,5,6,7,8 with a lot of those .9xx bores that were the true greats of the past.

Two bore, I dont think so. Only as a modern fantasy piece, like the 700.

I certainly would not consider the 700 as a fantasy piece. I am sure you mean 4 oz. balls and not 1/4 oz balls for the 4 bore. I am with you on all the big calibers. Whether it is a 4,5,6,7,or 8 bore, they were all used to take lots of game and all were used successfully. I like shooting a true 2 bore, diameter 1.326" diameter. But I have never hunted wither either 2 bore that I own.

I have been using 385 grains of pioneer FFG. It is about 15% hotter than black powder but cleans up a lot easier. It is equivalent to approximately 440 grains of black powder. A fairly comfortable load as far as recoil goes. My chrony is on the blink and not working at the moment. I would say about 1300 ft/sec with the 3370 grain ball if memory serves me right. 12640 ft. lbs is plenty. It could be pushed hotter, but I don't enjoy getting beat up as much as I used to. Maybe I am getting smarter at 50. NAH!! I doubt it.
