We got a Stoeger coatchgun in 12 guage. I'm happy with it and it's fun to shoot. But I've noticed that the last 1/2" of the bore at the muzzle is rough. It looks intentional as both are done the same and it's uniformly done - like it was done after polishing the bore.
I've read somewhere, maybe on this forum, a suggestion as a way to improve patterns when shooting loads with plastic wads was to roughen up the ends of the bore. The reason given was that the rough patch would hold onto the plastic wad just a bit and let the shot exit with less disturbance.
What I'm trying to find out is if the rough at the muzzle is a feature or a flaw. Anyone else notice thus in a Stoeger coachgun? Or have some relative experience with a rough patch at the muzzle end?
