I have a brand new 642-2 and upon initial inspection I noticed that the barrel bore from the forcing cone to the beginning of the lands and grooves looks a bit rough. Now from the lands and grooves to the muzzle the bore is nice and shiny. I need to shine a bright flashlight into the muzzle end to see this and if I don't shine the flashlight into the muzzle end you can't really see what I am talking about.
Also should I lube the trigger mech. with some light gun oil before using this new 642 for the first time?
So what do you experts think ?


Thanks

From the amount of dirt and firing residue on the barrel breech, I suspect that what you see is firing residue from the test firing.

Try cleaning it using bore brush, solvent, and swabs and get back to us.

It has been cleaned. What your seeing is dust.
I was wanting to know is if the area is normal when compared to other 624's.
Thanks

Lot of soot and residue showing around breech end of barrel. It may have been cleaned--sorta.

Yeah , but did you read my original post?
The question I had was about the condition of the bore inside the forcing cone up to where the lands and grooves begin. I don't care about dirt. I care about the condition of surface of the material of the bore.

Most of the forcing cone areas show irregularities and roughness. It really shouldn't pose a problem. The cutters used to set the forcing cone angles load up quickly because the Smith barrel steel is very hard, and the tools dull quickly. It could be lapped, but that adds time and cost to the process. Plus on the j-frames, there is not much metal to work with for removal purposes.

Yes, a few drops of oil into the action will help flow debris out of the frame. The new guns are pretty dry internally- at least the new guns I've worked on.
