Found some Hornady 90 gr XTP's loaded up 100 and took them to the range. Didn't work so well. The first magazine went well. The second magazine had a double feed. ProMag, maybe what they said about these are true, funny though, they always seemed to work well for me.
Put them aside and only use the OEM mags. Double feeds, dang, guess the Bersa don't like XTP's. Shoot them up in the TCP, worked fine.
Switched to PMC Bronze. OEM and ProMags worked fine. Policing my brass and, wait a minute, Sellier and Belloit. Never would function with those in factory guise either. Need to find some more XTP's, sort my brass, remove the S&B and I bet it will work fine.
