In Taylor's "African Rifles and Cartridges" he lists the 4 Bore as shooting a 1882gr bullets at 1330 fps or 7,400 M.E.

I haven't found the actual diameter of the projectile. The size of a bore as originally calculated was a 2 bore shot a half pound round ball, 4 bore shot a quarter pound round ball and so on. Using this calculation the 4 bore would shout a 1750 grain ball. However, when the went to conicaL bullets the weight increased.

According to the book "Cartridges of the world" the 4 bore was loaded with a round ball of about 1250 grains, or with a blunt or conical bullet that weighed about 1880 grains. Usual powder charge was 325 to 380 grains of blackpowder. Muzzle velocity was from 1300 to 1500 fps.
I have always wanted to fire one of those...:-)

Overkill,

From the African Hunter website:

"The so-called 4-Bore�s bullet diameters varied widely in the cartridge versions usually around .935 to .955 with the true one inch size normally found only in the old muzzle loading rifles. The 4-Bore size being an old reference measurement of 4-Balls to the pound of lead, which computes out to 1750 grains of weight. The cartridge rifles usually fired projectiles weighing around 1850 grains. I settled on a bullet diameter of .962, a weight of 1600 to 1850 grains and a case length of four and one quarter inches, which were the dimensions of Holland and Holland�s one and only Nitro loaded 4-Bore that they built for a Maharajah."
