Trajectory and pattern of US 3-inch (76 mm) Shrapnel shell of WWI era. The other factor was the trajectory. The shrapnel bullets were typically lethal for about 300 yards (270 m) from normal field guns after bursting and over 400 yards (370 m) from heavy field guns.

76 mm artillery includes 3 Inch and Russian 30 line calibre weapons, which are actually 76.2 mm. They were typically called 12-pounders or 13-pounders by the British based on the weight of the shell. They were typically called 12-pounders or 13-pounders by the British based on the weight of the shell.
The gun fired 3 inches (76 mm) steel, shrapnel, or explosive shells that weighed 15 pounds (6.8 kg). [2] The use of nickel steel construction meant that the M1902 could fire a heavier shell at a higher muzzle velocity and greater accuracy (due to tighter rifling) than any other field gun of American origin to that point.

First, the rifled gun's 2.9-inch or 3-inch bore was narrower than the 12-pounder's 4.62 in (117 mm) bore and could hurl fewer canister balls. Second, the barrel's rifling caused the canister to be blasted in an irregular pattern.
However, the shrapnel shell, named for Major General Henry Shrapnel of the British Royal Artillery, predates the modern high-explosive shell and operates by an entirely different process. [2] A shrapnel shell consists of a shell casing filled with steel / lead balls suspended in a resin matrix, with a small explosive charge at the base of the ...
Grapeshot used fewer but larger projectiles than were contained within canister or shrapnel shells. [1] Case shot broadly describes any multi-projectile artillery ammunition. The canister round is known as a case, so canister was sometimes called case shot and the term has confusingly become generic for grapeshot and shrapnel shells. [1]
The shrapnel shells in use were usually time-set to burst in the air above and in front of the enemy. Hence the gunners had to get within approximately 4,200 yards (3,800 m) of the enemy to fire on them. The fuze could be set to explode on contact (percussion) up to the maximum range, but shrapnel exploding on contact was of little use.
