I don't know if there are other shooters here that, like me, believe in and practice the barrel break-in of a new or older rifle by shooting jacketed bullets through their gun barrel and cleaning the resulting copper fowling from the bore after each shot for 10 shots, and then after each string of shots there after until the bore has become smoother from the firing and cleaning process?
I have never been able to spend enough time at the shooting range, to complete this procedure, in a single day. Shooting 70 shots and doing the cleaning necessary to remove the copper fowling to prevent copper build up until the bore is smoother, or the 70 shots have been fired and the necessary cleaning completed. This smoothing of the bore results in less copper fowling during firing of copper clad bullets in future shooting, and is also good for our cast boolit shooting. Any way my point is it takes many hour of bore cleaning to remove copper using this method of barrel break-in.
I am thinking that the next time I smooth a barrel bore in this way, I will PC the jacketed bullets that I will use for the break-in shooting and there will be no copper fowling, which takes too much time and effort to remove.
I have PC .22 jacketed bullets and then sized them back to .224" very easily with my Lyman 450 lube sizer. This coating could also be applied to jacketed bullets shot for any reason, to simplify cleaning after shooting.
What do you thing?
