I'm going to be using the following for IDPA this weekend:

4.2gr Win231
124gr RN Berry's Copper Plated
Win Primers/Mixed Brass

Does anyone have experience with this bullet/powder combo? This load was recommended by a guy from T's off the top of his head. Seems to be a midrange load from what I've found.

Tried the load out at the range today. Very accurate and feeds well.

I know primer flattening is a sign of excessive pressure, but this was a midrange load and the cases weren't bulged much.

Is this a common occurance for the 9mm Luger round? I've seen this on every factory casing as well.
