I am sorry for being late

CIP maximun lenght 53,30mm

for the 7,62x54R and also the 7,62x53R which also exist in the list the maximum case length are the same 53,50 mm for both.
cartridge designation isnt logic!

the Sako brass is 52,85mm

the LVE brass is 52,74mm

remember that the list giving maximum measurments for the cartridges. the factorys will be allways under this and different lots will shows some small difference also when made in the same year.
