Hornaday 9.3X74R

Hornaday 9.3X74R

9.3mm bullets have a diameter of .366". Until now, Hornady has not made a .366" bullet, although Barnes, Nosler, Speer, Swift, and Woodleigh (among others) do. Presumably the new Hornady bullet will be offered to reloaders in due course.

The 9.3x74R uses a long, tapered, rimmed case with a small shoulder set at a slight 5 degree 29 second angle. It makes you wonder why the designer bothered with the shoulder at all. (The answer is that the 9.3x74R's black powder predecessor, the 9.3x72R, had a straight-taper case and the smokeless powder 9.3x74R was designed not to fit in black powder rifles for reasons of safety.) The cartridge dimensions are as follows: .5116" rim diameter, .4685" base diameter, .4094" shoulder diameter, and .3905" neck diameter. The case length is 2.941" and the cartridge overall length is 3.665".

Traditional 9.3x74R ballistics call for a 286 grain bullet at a muzzle velocity of 2360 fps with 3538 ft. lbs. of muzzle energy. That is the load for which most doubles and drillings are regulated. It puts the 9.3x74 a little above the .35 Whelen and about equal to the .375 H&H Flanged Magnum in power. The cartridge has been used on large and dangerous game all over the world, particularly Africa, where it has been popular with European hunters for decades.
