Re: IDPA 9 mm power floor

I run plated copper Berry 147s at 3.4 grains with an OAL of 1.155 and mine chrono between 895 and 915 depending on temperature and pressure from a Springfield 1911 target model. I have chronoed them myself and was verified at the Texas State match last year. I have since moved up to about 3.5 grains. I hope this helps
