I am having trouble chambering "some" of my handloads. The rifle is a 300 wm. I am shooting 200 accubonds over 70.5 grains of imr 4831. The cases have been shot about 5 times. When I try to chamber some of them it is though the chamber is too short. If I force it, it will chamber but not what I want. I re-checked the lengths and even ran them through a collet body die for fear that the area before the belt is expanded. What I did notice is that when I forced one of them in and extracted it from the chamber, the area around the primer(outer edge)was very shiney, as though it was shaved off. Any suggestions? /ubbthreads/images/graemlins/confused.gif
