RE: Primers?
When I pop primers there are sparks visible at the barrel end.
Would "Bore Butter" have any effect on the contamination thought?
The problem is from the start no matter how many rounds or how oftenI swab the barrel.
As I stated in by other thread, I ran a PB thruogh the barrel to see how the rifling contacts the PB. Only the belt is in contact with the rifling. Maybe my bore is slightly over or the PB's are slighthly under .50. Any thoughts?
