I wouldn't use rifle primers in any .380. Some will say they are the same, but I will trust the people who MAKE them over "internet experts"
In my .380 bodyguard, my plinking/practice load is a
100gr berrys plated RN,
in front of 3.6gr of power pistol,
with cci small pistol primers.
Works very well. I got the occasional light strike before I got my lee factory crimp die, but have had none at all since I started using it....
power pistol meters much better for me than unique. I used to use unique in 9mm, but now use power pistol in both 9mm and .380. The only difference I noticed was the better metering, but I don't shoot paper much.....
