.284 Winchester
The .284 Winchester is one of a number of
useful cartridges that should have proven to be extremely successful but
didn't. Introduced by Winchester in 1963, the .284 was designed to squeeze
.270 Winchester
and .280
Remington performance from the new Model 100 autoloader and Model 88
lever action rifles.
In order to squeeze such performance from a cartridge short enough to feed
through those rifles, Winchester engineers designed the .284 case with a
rebated rim and a body almost as large in diameter as that of the belted
magnum case. The end result was a 7mm cartridge with about the same overall
length as the .308 Winchester but with the powder capacity about the same
as that of the .270
Winchester and
.280 Remington.
Any difference in performance between the three cartridges is the stuff pointless
debates are made of.
At one time the Savage Model 99 was available in .284 Winchester, and Ruger
produced a small run of Model 77 rifles in this caliber. Surprisingly enough,
Ultra Light Arms now builds more Model 20 rifles in .284 Winchester than
all other calibers combined. Which probably tells us that only those high
country hunters who are willing to pay for a 4-1/2 pound sheep rifle appreciate
what the .284 Winchester has to offer.
For open country hunting of deer and pronghorn, the .284 loaded with the
Speer 130 grain spitzer at 3100 fps will do anything the .270 will do and
it will do it in a short action rifle. Larger game calls for bullets weighing
from 150 to 160 grains.
H4831, H450, H4350,
H414,
IMR-4350, and
IMR-4831 are
excellent powders for the .284 Winchester.
