Berger Fullbores and IMR 4064
Loaded up some 80.5gr Berger Fullbores with IMR 4064 for a test run at the range tomorrow hopefully.
I used the Hornady OAL gauge to measure to my rifling and after reading some threads, decided to load 0.040″ off the rifling. My rifle measures 2.414″ with the Berger so I seated to 2.374″. I'm using new Lapua brass and S&B primers. The 4064 is like long grain rice so it makes for a pretty full cartridge, but I've been given some pretty solid load tips using it up to 25gr in .223 so I'm hoping for something good. CFE 223 will be my next test.
I loaded 5 rounds each at the following powder charges: 23.0gr, 23.5gr, 24.0gr, 24.5gr
Thoughts?
