Love/ Hate borescope

First off I've shot 10's of thousands of 22's through custom barrels in rifle competitions and checked barrels with a borescope. Never see leading or funky looking grooves.

So, with a new Hunter upper from Volquartsen this pic is the leade. Reason I borescoped it was couldn't get clean patches. Used bronze brushes and patches. Kept coming out Grey. The train track looking abnormalities go the entire circumference. All but one land has a burr. You can see the burr at 3 o'clock position bottom ofl land. You'll never shoot that out with 22lr. I have 4 uppers from Volquartsen and none look like this one. Yeah I checked them after t seeing this.
Waiting to hear back from Volquartsen as to what they might do.
Edit 4 Dec 24...Volquartsen is replacing it!

Two things that can really ruin a gun experience, a borescope is surely one of them, the other is a chronograph.
Interesting though, neither one will tell you if the gun shoots well, or not. You can get pretty good to very good accuracy with loads that have a fairly wide range of velocity, (as long as you don't shoot past a couple hundred yards), and rough bores with lots of cut rifling chatter can be excellent for accuracy, (at least until they really fill up with lead).

Ignorance may be bliss, +/-, works for most people.

A couple of my good friends -- who are fine shooters and much handier guys than me -- have 'em.
I figure I've got the best of both worlds. I don't have one at home and don't drive myself nuts, but if I should really need one, I can give the boys a call and take my rifle to one of them for a look.
So far, none of my rifles have acted up to the point I needed 'em scoped.
Key is, hang out with smarter people who have better tools ... but don't abuse their time.

That’s proper use of a borescope. I’d bet VQ will want this one back.
