Necchi, thanks for the post! I have a .54 which was bored to a 20 gauge/.62 smooth in percussion ... what I intended was flint, but a T/C flint .62 smooth are impossible to find, so I settled on percussion ... well when taking the nipple off the barrel, I felt an "oh, [insert cuss words]," and the breech plug began to turn and "ce la merde" (sp?) the whole thing came off with hand pressure ... now I have an "opportunity to excel," but here's the problem:
when I put the thing back on, it goes exactly a half a flat too far... now, if this were a build, this would be no harm done - simply take a very tiny bit off the breech face and advance to the next flat but in this case, all the stuff you add to the barrel after you time the plug is already there- -the sights, underlugs and so on ... [insert more cuss words]...
does anyone have any advice? should I plonk down some hard earned, God entrusted, overtaxed dollars at Track and buy one of their plugs and go for a flinter as I had originally intended... and if so, what about the finish?
aaaaaargh! I fear that I am rapidly losing my implacable calm!
