I only have these and they're LABELED
The opposite end of the box says " Power Shok"
*** DISCLAIMER ***
I shot several WT with these in 08-09 and FROM 150--389 yds !!
Parts of the bullets exited as shrapnel exits.
I pulled the rest of those and loaded GOOD c/c bullets FOR the 300 WM.
Main Point is Some Federal ammo uses Hot Cors....Some does (do) NOT.
