Firelapping Barrels Revisited

Although the Cabela’s 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 didn’t 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 that’s why the bore must be absolutely clean before checking it.
