I picked up 100 of these as seconds from Midway a couple years ago. They are solid copper, .30. cal, 168 gr. HPBT. They are machined and marked as match grade. They are excellent expanding bullets. I would like to get some more for a buddies .308 . I'm getting -3/4" groups at 100 yds
They are definitely not Hammers. Hammers quality far surpasses these. Like I said, they were packaged as seconds. They could be overruns. They are similar to barnes tsx but I don't have one in hand to compare to.
