Two cartridges showed up at the Czech meeting. Both have the Barnaul headstamp “БПЗ .223REM”. One of the rounds looked like a 30 Whisper (blt dia: 7.84mm-CL: 35.12mm) and the other appears to be a 6.5mm (blt dia: 6.73mm-CL: 44.25mm). The case mouth on both has obviously been trimmed after the case was finished.
Any ideas??? Guy who had the two spoke no English so no story came with them. Not sold, just given to me along with two or three other very nice items.
