Metric units mean nothing though.

on the S&B 7.62x54 sp ammo i got, it gives the primer size in metric. it is boxer primer
i just want to see what primers to buy to reload the brass

 

[mardig88]

on the box it says it is 5.3mm boxer
so i assume it is Large Rifle Primers

what size does the 308 use?

the primer diameter seems to vary between .2100 for remington to 2.120 for federal

could these differences in diameter cause problems with certain types of brass?
