Oh yeah, 50 buks says your target will have no idea about those scratches in the throat.
Your looking too closely, it's a problem you get when you have an eye for detail and a quest for perfection.
I wouldn't be wearing away more metal away just to make the throat look pretty.
I'd take that 50 buk bet
and the idea isn't to take away metal
It's simply impossible to polish away scratches without removing metal
but you are not going to try to polish away the scratch
no different to running in a bore the idea is to smooth the rough edge of a drilling burr or burrs made from chambering (or the scratch) to minimise the effect of ripping the projectile jacket as it passes the scratch that unstabilizes it after it leaves the muzzle,
the effect being similar to an unbalanced wheel on your car causing a bigger group so the target does know the difference
the reason why rifle bores (especially factory) can take quite a few shots to settle down before you get the best precision from them
I also reckon you would be there for a very long time using autosol to polish out a scratch, near impossible
and is the reason metal polishers use sandpaper to flatten out scratches before polishing
prepping your barrel before shooting it is not a bad idea at all
if it were barrel makers would not hand lap a bore which nobody would disagree makes a barrel better
