Ammo For Sale - Handgun Calibers
From Wikipedia, the free encyclopedia:
"The .284 Winchester is an example of a commercially rather
unsuccessful cartridge. Introduced by Winchester in 1963, the .284
Winchester was designed to squeeze .270 Winchester and .280
Remington performance from the new Model 100 autoloader and Model 88
lever action rifles.
The end result was a 7 mm 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.
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 Winchester
loaded with the Speer 130-grain (8.4 g) spitzer at 3,100 ft/s (940
m/s) will do anything the .270 Winchester will do and it will do it
in a short action rifle. Larger game calls for bullets weighing from
150 to 160 grains (10 g). H4831, H450, H4350, H414, IMR-4350, and
IMR-4831 are excellent powders for the .284 Winchester.[4]
These ballistics make it clear that the .284 Winchester is as good
as the .280 Remington with the same weight bullet. Of course the
short, handy mountain rifles for which the .284 Winchester seems
best suited seldom come with 24 in barrels. Aside from Winchester,
no other major company has ever loaded factory ammunition for the
.284 Winchester.
The .284 Winchester is not popular in Europe, where it competes with
the 7 x 64, to which it is almost ballistically identical. When
compared to the .284 Winchester the 7 x 64 has a lower C.I.P.
maximum allowed chamber pressure and as a European 7 mm cartridge
has a slightly larger bore. European 7 mm cartridges all have 7.24
mm (0.285 in) grooves Ø diameter. American 7 mm cartridges have 7.21
mm (0.284 in) grooves"
