Good morning Joel, and thanks for the pictures of the muzzle.
The moon craters do, of course, look horrible, but as previously explained, after the fouling shot in a BPCR, the "crud-riding" effect means that they much less important than one might think, as long as they are small and average out as far as possible bullet deviation is concerned. The deeper scoring is much more significant. And most important is the muzzle itself. However, all is not lost. You have demonstrated that the rifle shoots without tumbling the bullets. The craters can be softened by polishing the bore with Neco lapping paste (look it up!). The muzzle will have to be the subject of a seperate section, and as I am presently composing some thoughts on the problem of the heavy trigger, the muzzle will have to wait for a couple of days.
Don't worry - we'll fix it!
Patrick
