what is the biggest caliber weapon made?

Answer 1

Thats sort of a vague question.

In WWII the french built a huge line of defense known as the Maginot line, so naturally the Germans built a gun to break through this defense. It was called the Gustov gun, named for the designer Gustov Krupp. It weighed a crushing 1344 tons, including its railway carriage. With its breech block, the entire machine stood 4 stories tall, 20 ft. wide and 140 ft. long. Moving, positioning, loading and maintaining this monster required a 500-man crew. The Gustav's 800mm (31.5 inches) bore accepted two giant projectiles: a 10,584-pound high-explosive shell and a 16,540-pound concrete-piercing shell. The Gustav could strike targets up to 29 miles away.

Now thats artillery. The all-time most powerful cartridge ever fired from a conventional rifle is the .950 JDJ, which uses a 3600-grain solid lead projectile and a case made by shortening and necking down a 20x102mm cannon case. It develops a muzzle velocity around 2200 fps and thus about 38,000 foot-pounds of muzzle energy. A .50 BMG round has a little less than 14,000 ft-lbs. of muzzle energy. SSK produced loaded ammunition during the late 1990s but no longer does; they also custom-made a few rifles based on oversized McMillans with custom barrels and gigantic muzzle brakes.

Then Dardanelles gun has a 42" bore, but that will hardly fit into a gun case.

I've seen muzzle-loaders made from 20 mm auto-cannon barels, that is .82 caliber.

Andi I've seen some punt guns, that were 1.75" caliber.

Webley, Tranter, and some Belgian makers used to make revolvers in .577 Webley caliber, and Smith & Wesson has just recently put a .500 SD&W Magnum calliber on the market.

As some one mentioned, the .700 Nitro Express is the largest commercially available sporting cartridge. However, the rifles are handmade by Holland & Holland and starting prices run around $50,000.00 USD.

Answer 3

What is the biggest caliber weapon made? Why don't you narrow it down some, so people won't be telling you, "The H-bomb."

Example: The biggest elephant gun? Probably still the .700 Nitro Express (which has the widest bore but is only a special order if you can even get it).

Biggest shotgun? In the USA the biggest legal hunting shotgun is the .10 gauge; the biggest ever is probably the old .2 gauge.

Answer 4

The biggest caliber weapon is the Czar Cannon in Russia. It had a caliber of 3600 (36 inchs) and weights 85,000 pounds.

Answer 5

Probably one of those huge artillery guns the Germans built that was on a train car and could fire shells like 80 km over the English Channel.

Apparantly about the most cost-ineffective weapon ever built. Required a crew of thousands, the shells were so heavy that the barrel's rifling would be worn away after something like 50 shots.

Answer 6

I would guess probably the .700 Nitro Express. It is a .70 caliber rifle cartridge. It costs $300 for a box of 5 cartridges.

Answer 7

The biggest of the shoulder fired rifles are chambered in various 20mm cartridges. Such as the Finnish Lahti in 20mm Lahti. Plus, there are some anti-material rifles in 20mm vulcan.

Answer 8

The four shot Colt .60 caliber, you can only shoot it once or twice at the most.

Answer 9

If I recall correctly, the Yamato had 18" guns. There may be something larger, perhaps one of the old mortars from the 19th century, but I can't think of one.
