Ok. I have been trying to find an answer to this on my own but have not had any luck. I have reloaded about 5 times now. I usually fire about five factory rds and then about 10 reloads. I started with the lowest charge of Retumbo listed in the Nosler book. and proceeded to about 1gr less than the recommended max load. I am reloading 25-06 with 120gr Partitions using Win LR primers. I notice that I have 2 continuous conditions: 1) the primers ALL show a flattening compared to the factory rds. There seems to be no difference in the flattening from the lesser load to the largest load. Should I be concerned? 2) The neck of my reloads all show powder residue extending down nearly to the shoulder of the case. This is pronounced compared to the factory rds. I used the Hornady Lock n Load system to measure the jump and OACL. I did this about 6 times and came up with (I think) is an accurate OACL for the Partition of 3.168. The jump is about .050. Does anyone have any ideas?
Oh, and my shiney new ProChrono shows 3000s @ my max load of 56.5 and about 2800s @ 53.5.
