From their site:
FMJ, boxer primed, brass case, mostly 1980's production. This is surplus military ammunition; dates and types of manufacture may vary. A few rounds may not be IMI as the IDF used ammunition from a number of sources.
At $12.50 per box of 50, this seems like a great deal (depending on shipping) for 45acp.
Please once you receive it let us know how is shoots (clean / accuracy / etc.).
