[QUOTE="Remmy700, post: 1452104, member: 36564"] On new brass besides full normal prep I always run a NT mandrel through all the necks that is .002 smaller than bullet OD. This does two things. It works out any dings, but more importantly sets a consistent neck tension. Also are u running bushing die with expander button installed? If so try running it with expander out of the die. I tried RL33 in a 7mm and could never get what I was looking for and switched to H1000. Also you said 600 something rounds since you have removed any copper? Is that you have cleaned your gun but not got any copper fouling or it has been 600 rounds since you have cleaned the copper? [/QUOTE]
