I noticed a very odd listing at Exammo today for some otherwise unknown Sierra loaded 9mm ammo. They show both a 124gr and 115gr JHP 20rd box, which looks to be by Sierra with their Sportsmaster bullets, but they confusingly list it as being by Liberty Ammunition. The description mentions it being a “silver plated all-copper hollow point”, but the photo clearly shows a typical Sierra JHP bullet. Also shows a Shell Shock case in one photo. Sierra’s website shows nothing, and I can’t make out a headstamp.
