None of my Pvri 8mm Lebel has the annular case base groove, but the last was obtained a year or more ago.

Did do a range report and/or Milurps Competition entry using the ammo.

However, the last Grafs' order I got 8mm ammo of a different sort. (Delivered just last evening, in fact.) For the Steyr rifle that's been sitting "hungry" for several years!
