Picked up a bunch of brass from the range yesterday with a head stamp “ 7.62-M1A FC 70”. It weights 177.0g compared to my Lapua 308w at 173.5g. The FC brass was being shot from a bolt gun and appears to be once fired; all the primers had the red sealant.
How does this FC brass compare to say LC LR?
