I recently bought a Lyman Borecam Pro, just 'cause.

It's kinda scary actually seeing what's left behind after I "clean" a rifle barrel.

Anyone else here use one?

hunterjoe, sounds like I will be happier if I stay a blind man.

I bought the Canadian Endosnake borescope system, and it works well, although I am still blundering through the process of getting a clear vision...almost impossible to see plastic covering on the tiny mirrors.

It all comes down to what you actually want from the borescope and the way of viewing the “scene”. I have an Apple iPhone and iPad, so I opted for the wifi system so I can view things on them.

Slim...I couldn’t believe how much copper I was leaving behind when cleaning the bore...even after using plenty of bore cleaner/copper dissolver (Hoppes #9). I can still get bright blue patches a couple of days later...after getting clean patches the day before.

I inherited an expensive Hawkeye borsecope.
After using it & shooting & cleaning & shooting & not cleaning & shooting, I now use it to appraise throat wear & muzzle rifling on rifles a mate is offered as trade ins in his gun shop & nothing else.
Why?
Because after 5 or 50 shots, cleaned or not cleaned, I can't see any bloody difference in accuracy with my own rifles.

Yep, I have the Lyman too. Very interesting some times. My Security Six, which I KNEW was spotless, had a chunk of lead in the grooves. Also came in handy checking the gas ports on the ARs.

I have the original 36" flexible probe Teslong borescope and love it. Best $50 I ever spent. I also have one of their new handgun 10" WiFi rigid models, a rigid 21" rifle model and a prototype 36" reinforced flexible model they are testing as well. To be clear, the last three were sent to me for evaluation and testing for no charge other than an honest critique. Their latest models have some of my earlier suggestions built in as well as those from others. Company really listens.

Regardless of maker, those scopes can really be humbling. I changed my cleaning routine in its entirety.
