I just finished my first pcc build using a Kaw Valley barrel as well. I tried both BBI and Blue Bullets 125 TC at 1.12. Neither passed plunk test, but factory Federal at 1.15 worked just fine. What am I missing here? I have some Everglades plated 125s inbound to try as well. Very frustrated today. Loading on a Dillon 650 using Dillon dies. All rounds passed a chamber gauge. I had to go down to 1.05 to get one to pass plunk test.
