Pardini .32 ACP Lands?

Post by beeser on Mon May 11, 2015 8:38 pm

I noticed that there are two parallel lines on each land of a Pardini .32 ACP barrel.  I've never seen this before.  What is the purpose of this type of rifling?

Probably caused when the reamer was extracted in the lathe.

Scott,

The chamber reamer should not get near a finished rifling land.

Hi Jerry,
I think he is talking about the rifled bore and I was suggesting gauled material on the bore reamer or maybe even the rifleing slug.

A picture would be great to look at.

Scott,

The "rifling slug" or BUTTON might have had some grit that produced the artifacts that are seen.

I feel certain that Dave Wilson could get to the cause. 

One needs a highly specialized borescope-camera to investigate.  I no longer have access to
that piece of equipment.
