When to neck size?

[mlevimadden]

I know you can only neck size if you're using the same chamber, but im more questioning when is it worth it to only neck size?
For example, Im loading up some 243, 6.5 Creed and 6.5 PRC that will probably only ever be used in their respective rifle. All of these are using Hornady brass and are for hunting/hobby target shooting, no competitions etc. Is it worth it to spend another $50 per die for an RCBS Neck sizer for each one or does that not come into play until you're shooting competitions, using expensive brass, etc etc?

It is worth it to neck size if you want to maximize case life. It comes with a trade-off of more likelihood to have difficulty chambering, especially in a field rifle. There is a second theoretical gain that you can see better accuracy from older chamber designs with loose tolerances in the neck and freebore areas, but this is not as applicable with modern chamber designs from the last 20 years.

I don't know of hardly any competitors neck sizing. I'm sure some bench rest guys are still doing it, but the vast majority all of the field rifle competitors and hunters are full-length sizing to have more consistent ammo and reliable feeding and chambering for field conditions.

Even if you are neck sizing, you will get to the point after a few firings where your brass will no longer chamber without a full-length re-size.

I neck size on the first few firings to get the brass to fully expand to the chamber. Once that has occurred, I will full length resize 0.002” or so for the remaining life of the brass.

Nice aggressive comeback, I asked you a simple question.

No, you asked a question that was already answered with a basic reading of my first post, so either you didn't care enough to read, lack English comprehension, or simply wanted to insult.

I assumed you are smart and didn't lack comprehension and that as my post was short you have a long enough attention span to have read it.

I'll reply based on a lack of English comprehension and break it down.

I wrote:

I only full length size.

No implication of experience with neck sizing.

My reloads shoot fine and according to @Formidilosus full length sizing results in more reliable rifle function.

State a source, this is done because I lack personal experience to back up the assertion.

You asked:

are you just repeating what you have heard?

Well, I cited a source and made no claim of personal experience, so obviously.
