Firelapping Barrels Revisited
Reader Frechem wants more details about this gunsmithing process. Reader Licht wants details on Rays Valtro. Reader Conley wants to know where to buy Circle 10 AK magazines.
Although the Cabelas 45 groups got smaller, they were not the tiny ones I had seen others achieve via this process. I had seen a fellow writer do far better and also the examples provided by Beartooth had been better. Hence my disappointment. I have since learned there are limits to what can be achieved depending on things like fitting of the cylinder to the gun, etc. Next, I apparently didnt make it sufficiently clear that the felt slugging resistance can come from many things, such as barrel roughness as well as cramping from later machining processes. Also, the tighness can come from lead or metal fouling left in the bore before slugging, and thats why the bore must be absolutely clean before checking it. The Beartooth manual details exactly what and how the lead slugs accomplish removal of metal down the bore, not just at the leade. I suggest you get that manual and read it.
