Frankford Arsenal
(FA-T116 Cartridge) Experimental E1 Carton
The 6.35x48mm  experimental cartridge also
known as (FA-T116) from Carton E 1, same
as the.25 Winchester experimental that
was designed by Frankford Arsenal .
These were packed March 25, 1959.
It was one of the experiments in the mid-1950s
to  early 1960s by the USA and NATO to
develop a new Service Rifle Cartridge.
The cartridge was one verison based on the .25
Remington case, the (FA-T116) measures
6.35x48mm and  loaded with one 70 grain
which had a velocity of 3,345 feet per second.
However, the decision against the .223 was
overturned by further trials in 1959, which
again found the AR-15 superior to the M14
and recommended that its development should
be pursued as a replacement for the 7.62 mm
rifle, which had only been formally adopted for
service two years before.
