Foreign military .223 brass for reloading

[ballistic]

I have some mixed brass and wanted to know if anybody has experience reloading Malaysian MAL/1980s dated, and British RORG 1990's dated brass?
How about Guatemalan brass?
Any problems or issues for reloading?
Thanks.

So far I have found that IK and PMC headstamps have tight primer pockets and that might break your decapping pin. Those cases you mention will probably have a crimped primer pocket which need to be removed before priming. Look down inside with a flashlight and make sure they are not berdan primed (two hole).

ik have too small flash holes the pmc are great but must be decrimped
