I recently cast up several hundred of the RD165gr 30 cal bullets and installed gas checks with the lee sizer while sizing the bullets. I used some older copper checks that i believe were lyman checks. Even after going through the Lee sizer, you can pick the checks off with your fingernail. Is this gonna adversely affect accuracy??
Really dont want to pick them all off and resize them using hornady checks unless it is absolutely necessary.
Any thought??
I will shoot these in a win 94 30-30. Could use them as my plinking load with Unique if need be.
Thanks
Jeff
