Research notes
Experimental cartridge dating from the early 1970's when the search was on to find an improved assault rifle. One school of thought was smaller diameter, lighter and faster bullets. This 3.5mm version was an intermediate design by FN in Belgium during 1973. Initial velocities were impressive, but because of the lighter bullet, velocities dropped rather quickly as well as a host of other problems like wind, deflection in foliage and cost.
