Where is neck sizing taught

[AJC]

I guess that would explain why he could never measure shoulder movement.

I never knew to check. I never had a mentor and i am still trying to learn and figure everything out. I claim no great knowledge and i have thick skin so poking fun at my expense not really that big of deal. I will take my lumps as they come but comparing me to the great Guff that's going to hurt for a bit.

I reckon there’s several closet neck sizers roamin around

Yep, I'm one but don't own a NS die.
LCD's work best for this.

I have my father in laws 6mm REM that he had built in 1965 on a 40XB action. When he shot the original barrel out he sent it to Hart and had it rebarreled with a 26" stainless heavy barrell. In those days it seems RCBS was king. He sent fired cases and had a neck only sizing die made for that chamber. I have the die and it actually has my FIL's initials stamped on it from the factory. I neck size only with it until chambering/bolt lift get sticky (about 3 loadings) and then use a Redding body die to resize the body and bump the shoulder then size the neck. It's working well for me and neck tension is very consistant. What's your guys thoughts on this ??

Where do you find out if a loaded round won't chamber?

Like ive always said- you WILL have problems if you neck size. Kevin said that same statement above. Seems every week somebody comes in with problems that can be traced to neck sizing.

Early on it can be a struggle to consistently resize your brass. IMO, the easiest process is to send 3 fired cases that have been neck turned to fit your chamber. The 3 cases should have been fired a min of 3X. Send your cases to Forester & they can make you a custom full length die to match your chamber. It is worth calling Forester to have a conversation.

That what's been proven to work for you will continue to work for you if you keep doing it!

ONLY neck-sizing is a recipe for disaster. At some point neck-sized cases will have to be full-length sized to extract nicely the next time they're used.

Dusty can you please eloborate on why neck sizing causes problems?

And not the "my bolt is hard to close" problem as those that do neck size know that you have to shoulder bump or full length size every now and then as the case body stretches.
For referrence, i neck size with lee collet, and a redding boddy die when i get any size of hard to close bolt. Normally i get 6 firings from virgin brass bfore bumping the shoulders back the first time, then every 3 or 4 loads after that. Brass lasts a long time, and case prep time is reduced as i font have to lube cases then clean off the lube.. size, prime, charge, seat and fire

That’s exactly the process I use, Lee Collets and Redding body dies, on all my rifles, with the exception that I “anneal” or, actually, “temper” my case necks every third firing. I never have issues with bolt closure (and I reload for .204 thru .338 Lapua), brass lasts 10-12 firings (just 8 on my .338 Lapua), better than 1/4 moa down range, etc. I know this has been beat to death, and I apologize if it seems I’ve resurrected a dead horse, but every time I see these posts I can’t help but wonder if there’s something I’m missing or overlooking (always striving for just a little tighter group: it’s my stress relief).

To Ole Ed and Argh,

You all, IMHO, are full sizing your cases. Just not as often as others who full size after every firing and for their other reasons.

If Your reloading process gives you loads that puts your shots into the 10 or X ring 99% of the time. Continue on!
I full size every time because I can’t afford a stuck case at a match. And I want consistency.

And if a shooter is maxed out on a powder charge and only neck sizing, I think sooner than later he will lock up the action of the rifle.

To each his own to do what he thinks is best. Thank GOD for those freedoms.

I'm glad I had a Smith that actually shoots bench rest and a br shooting friend run me through the basics, A-Z. Wheat from the chaff.
I didn't have to sort out a bunch of internet hypothesis made by ppl who could "think it" and type.
I see so much I consider OFF THE CHART.
but hey...I only know how to make 6 br and competition pistol rounds.
FL w/ bushing, shoulder bump .... Easy & straight forward.

Neck sizing is taught on the high road Forum daily

This is what I was looking for. How and where is the technique being perpetrated. I've seen it also on Jonnys reloading bench for PPC. He used what he was given.

 

[Richard Coody]

There really is no right and wrong in reloading techniques. Only what works for you. People have success with all these different methods.

Beware the reloader who says this is the only way.

 

[AJC]

I am really curious if one was wanting to have a custom die made with 3x fired brass if neck sizing would not give a better result for the purpose of having a full length die made. Would it not work the brass the least if done this way? To be clear this die would only be best for that one gun/barrel until the barrel needed to be changed. Still trying to learn!!!!

Sure thatll be fine

In essence that's just a FL custom die.
Sure it works the brass less than resizing back to min SAMMI spec and the neck might get a little less work but still more than an LCD works brass.

 

[Richard Coody]

Well i have lee collet dies and redding body dies. They create good concentric ammo very economically

I also have custom dies by whidden, Neil jones and harrells

Now for the overworking of brass comment. I hear this all the time on this forum. How many here retire cases from split necks?

My experience is primer pocket failure is what ends brass life for.me.

Reloading techniques vary with what you are.trying to accomplish. Quite a difference between getting.a bench gun to shoot in the ones and twos and getting a hunting rifle to shoot half Moa groups.

Buying custom dies for.a rifle that is not capable of showing the difference is just.a waste of money.

This dead horse again! All of he methods have its place.

Tommie, I don't think anybody is saying it can't work, just that it isn't good for beginners, and it may not deliver BETTER results than careful use of an FL die.

I’d go further. In virtually every situation, there is zero accuracy advantage to neck-only sizing, and it’s likely neck-only cases will have to have the shoulder bumped every few firings or else sticky extraction will occur.

Every LR BR competitor I know and shoot with bumps the shoulder around .001 to .002. One fellow, who has NBRSA Hall of Fame points, shoulder bumps AND small base sizes his cases before each Nationals. I have experimented with small base sizing as well and haven’t any difference in accuracy at 600 or 1000 yds either. This data point is completely counter to the idea that a neck-only sized case is more accurate because it fits the chamber better.

I think the idea that neck-only sizing is better was propagated by gun writers 40-50+ years ago. The initial ideas were to set the sizer so the shell holder touched the sizer die, seat the bullet to the COAL length without measuring ogive, and reloading was often presented as a way to same money on ammo. All this was mainly for factory hunting rifles with the typical huge chambers.

Of course neck-only sizing and seating with the ogive would give better accuracy, but there was often that sticky case issue after three firings. Somewhere along they somebody discovered that you could get at least as good if accuracy by bumping the shoulder .001 to .002, and that pretty much resolved the sticky case issue.
