Doesn't look like it was hardly used, and how much can a eastern woods rifle be shot, I mean sight in in, take a few shots each year you hunt to make sure it held zero, and hopefully get a shot or 2 at a deer. The rifle looks more like it sat for years in a closet.

So I figured to give it a thorough cleaning today, and coincidentally, my son gave me an early Christmas present of a Teslong borescope.

First 3 patches on the top left are a dry patch to push the loose crud out, and then 2 soaked in Hoppes #9. Let it sit for 20 minutes, then ten strokes with the bore brush soaked in the same, and sit for another 20 minutes. then the lower left 3 patches and it looks decent. A few dry patches, then the first patch on the right, soaked in Shooters Choice and let it sit in the barrel for 20 minutes, followed by 20 strokes in & out with the bore brush followed by 3 wet patches with the Shooters Choice, and I can't find a bit of dirt or "blue" on the last patch so I say to myself, this bore is immaculate, there isn't any copper in there.

So I figured I'd prove to myself how well I can clean a gun and got the borescope out and got it working and holy chit, I'd have never believed there could be any copper in that bore and I was WRONG again, LMAO.

Plenty of copper in there, despite the fact I'm sure the gun has a low round count.
So my question is, is it that Shooters Choice not a strong enough copper remover and I need something stronger like Montana Extreme, or is it going to require JB bore paste to get this copper out?



How does it shoot?
