I finally got around to sending the camera down the bore of the Winchester 1873 I pick up on Friday. Someone needs a good talking to about bore maintenance!!!

I'll post up some pictures of a good barrel so you can compare.

These pictures were taken with a $34 bore scope a few of us gun nuts bought on Ebay from Hong Kong. For the $$, it works pretty good....

Man, that looks like hundred year old cast iron sewer pipe!

Can you say "firelapping project"? :rolleyes:

Man, that makes my teeth itch looking at that...hope your the patient sort!

Borecopes are a blessing and a curse eh?

You can see the burrs on the edge of the rifling of the 1871 Pedersoli Remington Rolling Block in 45-70.

That looks like it would improve with fire lapping.

[rbertalotto]

Yup, I saw those burrs, but the rifle shoots so good I don't want to mess with it. I'm more concerned with the start of a little "cracking" in the throat area.

[Doc Highwall]

I would fire lap it but use 800 as the courses grit and make sure it is a non embeding or non charging compound.

What I did last time i hade to fire lap is I coated a patch with compound to coat the bore as well as putting it in the grease grooves.
