That sharp, shiney bore at the gunshow

[zfk55]

So that super bright, shiney and sharp bore seen with the Borelight convinced you. This is the one! Most all cared for barrels look just like that with the Bore light. Clean out the copper and carbon and that's just what it looks like. Sharp, shiney and bright.... with a Borelight.

This rifle's bore looked exactly like that with the Borelight. *Enter the Hawkeye Borescope*. When we took these shots our borescope video setup wasn't working, so we simply used a camera pressed against the Hawkeye eyepiece, so the quality is "ok", but with the correct hookup it's a sharp as a DVD.
I can't tell you about the rifle because it would unnecessarily embarrass the owner, but it was sent to us for evaluation. A very expensive rifle that had a severely damaged bore with the lands beyond salvage, but with a simple Borelight it truly did look pristine.

Keep in mind that when the guy at the gunshow hands you that rifle with a borelight, you don't always get what you expect.

And this is why that $1,000.00 investment in a Hawkeye Borescope is worth every penny.

I wish I still had the original shot with the Borelight for comparison, but I can't find it. It truly did look perfect.

Yep - Caveat Emptor..................

Why a peek with natural light, straight or reflected from a small piece of white paper, is waaaaay better than a bright borelight shining in one's eye's, throwing glare, etc.

What in the world would cause those cross-hatched grooves in the second picture?

While it's a necessary investment for a gunsmith, it's worth keeping in mind that I can buy three match-grade barrels for my Savages for that amount...it's all relative.

 

[zfk55]

For us it was a necessary purchase. We're constantly evaluating barrels in-house and for others.

Those marks are from a device used by the owner to try to clear a barrel blockage. With just a borelight they weren't visible. I really don't want to elaborate on what happened with this particular rifle, but later I'll post some others that are far more difficult see see without a borescope.

Firecracking is extremely difficult to see without a borescope, but most rifles in small projectile, high velocity have them.

zfk55 what is the magnification of the scope?

 

[zfk55]

Funny, I never thought about it. If you buy the one that will fit in a 223/22-250 it works great in a .30 caliber. I'll have to check the manual. I think the magnification is very low because the refractor mirror is right there at the lands/grooves. I'll find out.

As an expert experienced in quality control, demonstrated reliability, inspection and measuring, I can say that I really admire the way this OP thinks and does his work.
