I have loaded a few hundred of the Powerbond 124g RN 9mm and the 230g RN .45 ACP. I started out the 9s in the mid to high lead range. I stuck with low FMJ for the 45. No issues. They loaded and shot well appeared to be very accurate at 10 to 15 yards. IIRC I loaded the 9mm 124s at 1.135 OAL as they are slightly longer than others I have loaded for. No issues in a Sig P6 and a Walther P1.
I believe they are a good product for plinking. I have not pushed them and have no reason to. Others will have to chime in on accuracy at greater ranges.
