You can smooth the swiss bolt out even more and the trigger too. I took my swiss bolt apart and cleaned it and lubed it with moly. I put moly on everything that turns and has sign of rubbing/friction even on the firing pin rod/spring too. I put it on the two barrels of the bolt body and in the slot where the bolt rod rides in too. It allows the bolt to reset the firing pin turn and pull back much easier and smoother too. Put some moly on the trigger sear on the bottom of the bolt too it will lessen the trigger pull even more too. I put some on the bolt lugs too just operate the bolt and let it work into the pores of the metal. The more its worked the smoother it will get.
This works on any gun wether its bolt action, semi-auto or full auto pistols and rifles moly is the best lube on the planet.
