I knocked up some loads this morning prior to a bit of range work. The difference from the other loads was that I used norma brass instead of remmington and seated the head a little lower. Blaser R8 Cal is 6,5 x55. Lee dies
When I came to load I found the bolt would not push fully home that easily,normally a firm flick of the wrist and the bolts home and fire away. This time I had to definately push the bolt to the end of the travel.
I seem to remember reading about excess case lube being a possible reason? I used Lyman greasey horrible stuff, ...its going.
Oh the grouping was 1" at 200m
