What do you see?

[MUP]

I just cleaned my CZ 457 VT and took a few pics inside the barrel. Do I have lead buildup? I really don't know what I'm looking at, or what to look for, so all help and advice is appreciated.

 

[MUP]

Also I don't really know how to adjust the bore scope either so any tips regarding how to focus better or adjusting the lighting up or down would also be welcomed.

Looks like some lead, however, got no idea what kind of scope but you are too far away with glare. You need to be in the bore looking head on.

Good news is you definitely have no carbon ring at the end of the neck. So far as the rest of it it's really hard to tell. The focus isn't bad but I think you need to increase the light intensity. If it's a Teslong it's adjustable.

It is a Teslong and I tried going back and forth with the light adjustment, it seemed to lag behind, as I would roll it up with no change seemingly, then after a few seconds it would change brightness.

Are the little streaky looking strips the lead? There seemed to be quite a bit of shine along the rifling grooves.

All I have for cleaning is what I normally use for my centerfire rifles, Bore tech copper remover, Rem 40X, and Iosso. I think the boretech keeps the carbon ring at bay, although that's about it for that solvent, but I start with it each time, then scrub with 40X.

To sharpen up the focus look at the end with the small mirror and light and you'll see a small lock nut below the mirror housing. Loosen it and turn the mirror in or out and tighten the locknut. It's a trial and error thing, so.....

Adjust the borescope to improve focus as advised above.

Clean the bore regularly using a .22LR cal bronze brush and a solvent. Leading, carbon rings don't become a problem.

Before shooting for score, foul the barrel with half-a-dozen or more rounds with the same kind of lubricant used on ammo used when it counts.

First three photos look to show leading streaking to me. Not an expert but .......

To focus the lens or image loosen the mirror and loosen the lock ring then turn slightly to adjust the image and relock the lock ring to the lens holder. Will get a much better clear image

I didn't catch that this is a .22LR so that's my mistake. It's quite possible that the bore looks dark from fouling.

Are you disappointed with the rifles performance on target and trying to find the cause or have you just decided to scope it and are trying to interpret what you are seeing?

Just wanted to check the barrel and see what it looked like mostly. It's shooting fine still, well, unless the wind is blowing...I suck at adjusting for wind shots. :/

Thanks for all the help guys, much appreciated.

If it's still shooting ok I wouldn't worry about it. 22LR is a different beast than a centerfire. I'd just keep doing what you've been doing and monitor what you see.

I've only ever put a brush to it one time, as I've found conflicting info about using a bronze brush potentially scratching the rifling? So far several patches, short stroking several times with each solvent, dry patches at the end then a wet patch with CLP to coat for rust prevention till next outing is all I've done with regards to cleaning the barrel.

Shooters in 3P competition (Olympic style shooting) regularly use bronze brushes. In fact, rifle makers such as Anschutz and Bleiker specifically recommend their use. Many serious BR shooters using custom barrels also use brushes.

It's safe to use a bronze brush without fear of damage. Remember to use a proper bore guide and a good quality rod.

Why would you assume a copper solvent is great for carbon? I would be careful with the IOSSO, not good for regular use, last thing you want is to polish the inside.
Nothing beats C4 for carbon ring…..zero scrubbing/polishing.

A brush is not gunna hurt anything.
