Wouldn’t it be more important to check cleaning procedures against actual live fire performance?

A bore scope is what? $55 on Amazon these days.... No real good reason not to have one and you can physically see what's going on.

Well, yes.
What I was trying to say is without seeing what the actual condition of the bore is, you really don't know how clean or not it is.
I think it would be easier to correlate a condition in the bore to accuracy on target than just some cleaning procedure [without knowing what the actual condition in the bore is].
And, let's be honest, most/many of the posts about cleaning are focused just on getting the bore clean - without any reference to results on target. My point here is that if you aren't looking at the results of the cleaning, you just don't know what works to get the bore clean or not.

Barrels often have preferred states of cleanliness, based on targets. A bore scope can tell you if you are hitting that goal or if things are stacking up gradually changing the after cleaning condition. If you are shooting competition you really want to avoid having a barrel stop shooting in the middle of a match, and then having no way to determine whether its degree of cleanliness is the reason. The thing that I particularly like about the Teslong bore scopes is that as cheap as they are, there is no reason not to take them to the range.
Unless it's a blue Iosso brush with Iosso applied......

I only use a patch for abrasives
The point being that Iosso on their proprietary nylon brushes is a very aggressive bore cleaner. More so than JB on bronze brushes.

LOL! I have been shocking Frank for a long time. However, I really only care what my target and borescope tell me. Frank will probably survive my shocking cleaning methods.
From my targets and borescope I can say with high certainty that Iosso on an Iosso brush is very aggressive and should be used infrequently when other methods fail. I can also say with high certainty that a bronze brush works very well and doesn't harm bores.
The case Frank likes to bring up is the genius who heavily cleaned his barrel with JB something like every 11 rounds and in 250 rounds the barrel was toast. A similar case is the guy who spun a nylon brush on a drill to see what happened to on old barrel. It should be very obvious why those two cases came out the way they did.........

Not sure if I'm reading correctly, but are you saying that Montana Extreme copper killer is actually the best "carbon" remover you know of? Cause I'm always looking for more effective carbon removers (copper is easy to remove/dissolve...but not carbon). If so, I need to try!
Also, as for bronze brushing and crowns...what type of crown do you prefer...beveled or square?
Thanks!

When I've used Iosso on a brush and with 30 or so full strokes every couple hundred rounds [so, maybe 10-15 times on a barrel] I have never seen any gouges or scratches in or across the lands or grooves. I just have a hard time imagining how Iosso/JB/Flitz/KG 2 would make those deep gouges in the pics.LOL! I have been shocking Frank for a long time. However, I really only care what my target and borescope tell me. Frank will probably survive my shocking cleaning methods.

I did one with a piloted 60deg center cutter one time and it made no difference
This sure seems to be one of those things where there is no one right way to skin this cat! By hunting rifles, would you include squirrel/prairie guns in that as well, where a typical shooter might expect a 1-12 or 1-14 6BR to go 5,000+ rounds?
How deep do you like ro chamfer, and piloted?
Thanks!
No difference between beveled and flat/square...or between beeline with piloted tool or some type of point cutter?
Thanks!

The chamfer is mainly for rifles that will be handled a little rough. A bench gun goes from a case to the bench and thats about it. Plus those guys are careful about cleaning. The chamfer is more durable than a sharp crown as well. If you were going to put 5k rounds on a 6br I would chamfer it. Just enough to break the edge, single point cermet insert in the lathe.
