Samppa howcome you don´t remeber that s309 is stamped on ammo box JVA317???
s309 just name for .310 bullet in militaryload just like US marks m193 (55gr) or m855 (62gr)
s405 is Lapua civilian marking for .310 bullet (they are actually quite thinner. One Lapua sales rep once told to local deathdealer [the one here in kymi that looks like Santa from Hell] that .311 label on box just means that bullets won´t be thicker than that.
s374 is marking for .308 123 gr fmj, basicly the same bullet as s405 but with additional canellure for recocknation (spelling?)
for s409 don´t know
tracer jva313 and bullet is marked as swedish...
anybody with ALS (aluminiumcore training bullets) box what does it say??
