As far as an individual weapon goes (vs. a crew served one), it would be the South African Denel NTW-20x110 and Croatian RT-20, both of which fire a 20x110mm cannon cartridge of the sort originally designed for the Hispano-Suiza antiaircraft cannons.
The most powerful handgun is thePfeifer Zeliska Revolverwhich fires custom made .600 Caliber nitro magnum ammo
Muzzle velocity 462 metres per second

A contender for First Place in the power contest may be the Maadi Griffin, although there is contention about how many were made. This is a bolt action pistol in caliber .50 Browning Machine Gun. Who would want to shoot it, or the Zeliska, is a subject for philosophers.
metal storm have developed a gun more powerful and faster than any gun before. using new technology the only part of the gun that moves are the bullet's. tests have been recorded an using the data the metal storm machine gun can real of rounds at a mind blowing rate of 250,000 rounds per min!! if u don't believe me Google the fastest most powerful gun in the world an click on metal storm!!!

The Japanese Yamato class battleships had 16.1 inch (400 millimetre) guns - the largest ever mounted on a naval vessel. Those would be likely candidates.
Yes though the Japanese gun was bigger but the American 14 inch naval gun could with stand higher powder loads safely in turn increasing range and penetration of the hull of the enemy ship. Smaller but more powerful the 14 inch was many historians would say.
Speaking of powerful guns around that period the most powerful gun was made by the germans. It was called Gustav and it was an 800mm or 31.46inch rail gun which took up two standard sized railroad tracks (for it was 23ft wide) and fired a 4.8t high explosive projectile at 2690ft per/sec which could level entire city blocks. And a 7.1t armor-capped projectile at 2362ft per/sec. And could fire at ranges up to 30 miles. It weighs a massive 1350 TONS!!! and stands a whomping 140ft tall and as i said earlier 23ft wide. Despite its immense power it was extremely impractical because it took a crew of nearly 5000 people to keep it firing (including protecting it) not to mention the time it took to line it up using a circular railroad track and was limited to this track it sat on.
Guns in the military means artillery. Small arms are rifles, machine guns, pistols, etc. The most powerful guns in the Vietnam War were: 1. The US Navy's battleship, USS New Jersey's 16" guns (9 of them; 3 rifles per turret, three turrets). 2. The US Army's 175mm Self Propelled Gun. 3. The US Army's 152mm Gunned M551 Sheridan light tank, which was assigned to US Armored Cavalry Squadrons. The official name of the M551 Sheridan was "Armored Airborne Reconnaissance Assault Vehicle."
One of the largest and most powerful was the WWI "Paris Gun" developed by the Germans. It fired a 210lb shell about 81 miles. The gun weighed 256 tons. It was not very accurate but an effective psychological weapon.
Some people have made handguns chambered in .600 Nitro Express (an elephant rifle cartridge) and in .50 BMG (made to shoot 2 miles in a machinegun).
Neither has any real usefullness in a handgun.
The most powerful production handgun is Smith & Wesson's .500 S&W Magnum revolvers, while the most powerful handgun manufactured was the .600 Nitro Express revolver, which is not a production pistol, but can be custom manufactured on request by Pfeifer-Zeliska for a "humble" price of about $17,890.

First, it is rifle, not riffle. Second, no, or we would shoot tanks with a rifle. Cannon are more powerful. Finally, depends on the rifle. I have a .22 rifle and a .44 magnum pistol. The pistol is far more powerful than the rifle. I also have a .22 pistol, and a 30-06 rifle. The rifle is far more powerful than the pistol (in THAT example).
The most powerful cartridge developed specifically for civilian use would be the .585 Nyati.
