Difference of thickness of walls of brass!
 
I have a lot of brass! But they differ in the thickness of the brass walls (at the points -neck brass)! The difference in the thickness of the walls of brass <= .0037 inch
How can I improve brass???
Please advise me!

Don't despair-all you have to do is turn the case necks. What you do is get an outside case neck turner, measure for the minimum thickness, and turn them to all the same exact neck thickness. That way they'll all be uniform with same neck tension.

In practice, what is it? If you explain to an amateur, what action and what equipment do I need?
I have 2,300 pieces of this brass!

Might I ask what type of shooting you are doing that leads you to believe you need to neck turn your cases? Bear has already given you the basic information you need to know, but if you want specifics it will require a much longer and detailed explanation of the process. It would help to know what it is exactly that you are trying to achieve here.

There is a series of videos on youtube that attempts to explain the subject, but IMO it is so poorly narrated I cannot recommend that you view it. I feel that it would only lead to frustration and more confusion.

There are many folks here that can explain the process much better than myself I'm sure.... :p

Friend just a made a gift to me, a lot of brass 9para! but, brass with a defect (I wrote about him)!
Therefore, I am interested in information-the list of tools to remove such a defect!
I do not quite understand, the equipment for reloading-removes the problem? Or only on a lathe?

Do not despair. Diffeences in 9mm brass are not a large issue. Segregate by brand (headstamp) and load it up. The slight differences will not make a noticeable difference in this caliber.

Agree with robocop. Neck turning is for rifle cases. Reload it as-is and shoot it. :)

This is good news!
I am however, confused (like an engineer)!
Since I do not understand (essence of the theory)!
The axis of the barrel, will not be identical with the axis of the bullet cartridge (located in the chamber of the barrel)?
In addition, there is such a thing such as "entrance bullet" in the chamber the barrel?!
The bullet will cling (in the place of a thin neck brass),- on annular protrusion(fixing brass) in the chamber?!
Where am I wrong?

robocop10mm 11-23-2009 01:22 PM

Yer not from round these parts, are you boy? Just kidding.

Im having a little trouble with your phrasing. Let me give it a try. The axis will be off a little but I doubt you will ever notice. Handguns are not long range rifles. Your shooting skills will never get good enough to warrant worry about such things in straight walled pistol cases.

As far as the rest? You lost me.

..... hmm, I'm just thinking logically.
p.s. At the specialist in the reloading-I do not claim !)))
