unrifled

It was made from stamped steel with an unrifled barrel.

Maybe their cannons were bigger than the typical unrifled short barrels.

I am stripping our artillery of all the smooth-bore, unrifled cannon that can be found.

It fired a .45 caliber pistol cartridge from an unrifled barrel.

The weapon was a pistol with a short, unrifled barrel having a bore approximately fifteen millimeters in diameter.

The design eventually settled on for the Mk I featured a 4 foot unrifled steel barrel.

Soon, while the crews were awaiting the arrival of the ship, the body showed symptoms of sinking with all its treasures unrifled.

Along with the unrifled (smooth-bore) barrel, this high rate of fire will no doubt further lead to extreme inaccuracy of the gun.

"I assume the Palace safe remains unrifled, Mr. Kelly."

These were later supplanted by unrifled muskets fired by a flintlock mechanism, which became the weapon of choice because it could be fired relatively rapidly (six shots per minute).

Large calibre APFSDS projectiles are usually fired from smooth-bore (unrifled) barrels, though they can be and often are fired from rifled guns.

The bullet was short for its caliber, made of steel, and round-nosed-not a very accurate projectile for use in an unrifled firearm, because it would have a tendency to tumble in flight at any range beyond a few dozen meters.

The bullets, each one wrapped in a leather patch that was designed to grip the barrel's rifling, had to be forced down the tight grooves and lands of the barrel, whereas a musket ball could be rammed fast down a smoothbore's unrifled gullet.
