My Sp101 has leading issues and wondering if you might offer some suggestions what to try. The cylinder throats are all consistent at .357. My bore slugs at .355 , maybe closer to .354, which I consider tight. My boolit is 358156 with gas check, sized to .357. Javlin lube. Load is 6.5gr Unique.
No discernible tights spots in my bore which is smooth. I tried my own poured from WW and also tried commercial boolits which where quite hard (but w/o GC). Brass is 357Mag (not 38spcl). Tried alox as well for lube.
Pretty much run of the mill load and shoots well in my other 357Mag's. I do not have .358 sizer or I would try that but having a hard time believing that would solve the problem.
The leading is heaviest right after the cone. Cone is fine. Leading is consistent even if I vary lube or boolit type. Not horrible terrible leading but much more than I am accustomed to.
Any thoughts?
