neck size only ?

Because eventually you’re going to get tight cases that can mentally or physically affect your performance
Tight cases often shoot fast so there goes your vertical and if your feeling a tight bolt close suddenly your thinking of that and worries affect results.
I’ve never noticed an improvement in ES with neck sizing.

In fact I found improvement in vertical sizing the entire case for my ELR stuff

As far as the lazy part nothing is as simple and fast as running a case through a Lee collet brush neck, One pass in press with absolutely no lube and your ready for primer, powder and bullet.
I get what you are saying, which is why I limit neck sizing to only two firings. Ultimately, people need to do what works best for them and their rifle.

I have to lube regardless, because I don't simply run it through the neck die, and I have no experience with the Lee die. I run it through a Forster neck bushing die to size the neck and bump the shoulder, then I run the case through a neck expander mandrel die. I dip the neck in dry lube, knock off excess powder with a pencil or something before running it through the mandrel.

When I give advice to friends just starting out I tell them the mandrel expander is a must, imo, for consistent neck tension. It pushes the inconsistencies to the outside of the case and doesn't risk messing with the shoulder bump like an expander ball can.

I only go through this trouble for precision rifle. My gas guns get an Rcbs short base full length sizing and done.

Two is a safe compromise, I found 3-4 was as far as you could go and not get issues if you’re running reasonable pressures.
 
Bill, what the hell ya mean old days, lol;-). Lol, I recall searching all over kingdom come for neck dies for some of the odd balls I had. I even threw out some pretty heavy coin for custom neck dies.
A few short years i find it interesting what we as a group have learned.
I will admit to still using a neck die on some orphan project guns. A standard size die or body die may size to much of a sloppy/generous chamber is involved.
I maybe I shouldn't say old days it makes many of us seem old and guess in a way it does seem like just a short lifetime ago but I don't think I've used a neck sizing die since the early 80s. Even before knowledge of bushing dies trickled out in the sticks where I grew up I had started at least using full sizing dies even though would mostly just have them where they were just bumping the shoulder back slightly.

You are right it's crazy the knowledge that has started really spreading rapidly since the internet and especially the past ten years. As I mentioned it was probably the 1990s before I knew of bushing dies and the benchrest crowd had probably been using them for a couple decades.
 
One can equal the case alignment issue with only sizing a portion of the neck which will allow the un-sized portion to align the case with the chamber as well. A bushing die would be required.

I agree, that's where the Wilson inline neck bushing die comes in, sizing only part of the neck. I do this after body sizing in an appropriate body die or in a FL bushing die without a bushing.
 
expedience: no lube to futz with. wipe neck, size, and go.
Yep. It's quick and easy. I'd love to have a run out gauge just to know which gave me better run out. I'll bump shoulders with a Redding body die pretty much every time. I'll anneal and tumble/polish/trim about every other firing. Even though I don't compete I shoot long distance and I want my cases to be as uniform and similar as possible.

I've never gotten one stuck in a chamber before, but I have gotten a case stuck in a $150 body die :mad:

Hard lesson learned!
yikes. yet another reason to size, then mandrel i.d. in a second step. the other? i found on the issue of runout that i get better results pushing on the neck with a tapered mandrel rather than pulling on the neck with a button.

Agree 100%. I switched to using a mandrel die a few years ago and never looked back.
 
Alright my little test using a free floating shell holder, I will say I cannot draw any conclusions as of yet, reason being, The Lapua brass I used is 1x fired, and was fired from another rifle I had yrs ago, IMO that brass is not fully formed, it needs to be fired a few more times in my match chambered rig before I try to try my test again, my body die is set up for my match chambered rifle, also I did not notice any change in my runout on my collet die, it's still 1k or less every time, the brass has been cleaned and annealed, I ran 10 cases from the same case weight batch, I will post another thread once I get my brass in the order I want it in,
