The
.32 Winchester Self-Loading
(also called
.32SL
,
.32SLR
, or
.32WSL
) is an American
rifle
cartridge
.
Description
[
edit
]
Winchester
introduced the .32SL and
.35SL
cartridges in the
Winchester Model 1905
self-loading
rifle, a
centerfire
version of the
Winchester Model 1903
. The .32SL never gained popularity as a
hunting
cartridge, although it may be suitable for the largest small game such as fox and coyote at ranges under 150 yards.
[1]
Both the .32SL and .35SL were soon superseded by the introduction of the more powerful
.351SL
in the
Winchester Model 1907
.
[2]
When first introduced, however, the notable firearm expert
Townsend Whelen
noted the .32SL cartridge as displaying similar
ballistics
as the
.32-40 Winchester
black powder
, low-pressure cartridge.
[3]
He further suggests the best use of the .32 SL as being for rapid-fire
target shooting
for ranges up to 300 yards. Within such ranges, it is quite an accurate cartridge.
In October 1940, an Army Ordnance circular suggested development of a light rifle using a .30 caliber cartridge similar to the "Winchester Self-loading Cartridge, Caliber .32" to replace the pistol and submachine gun. This led to the production of the "
Caliber .30 SL, M1
" cartridge directly based on the .32 SL in February 1941 and, after a design competition, adoption of the Winchester-designed
M1 carbine
in October 1941.
