Neck resizing

Thoughts on neck sizing only on brass only fired out of your gun?

How are you planning on sizing the neck, neck sizer or only partly screwing in the full length sizer?

I use a full length sizing die on any brass that's not been shot specifically out of my rem 700. Once fired in that one rifle I'll run that brass only through a collet necksizing die and place with that particular rifle. After about 2 firings I'll anneal and then full length size again. I only do this in my bolt guns. FLS in my gassers

Was watching a fella try it with a full size die and he couldn’t get it to do it correctly, is why I asked.
He was sure he wasn’t doing it right and is opting the neck sizing die

I've been neck sizing with lee collect neck die then bumping shoulder slightly with body die.
Great trick to get zero run out and not invest in real expensive bushing dies just spend the extra money on good bullet seating die.
My groups have tightened up a lot and its not nearly as confusing to set up
Started this in 308 and will be doing other cartridges same way in future luckily I have collet dies for the other cartridges already
Getting that little bit of shoulder bump back seems to be helping alot

The lee dies will size the necks straight but the one I tried couldn't give me enough neck tension and it finally broke when I tightened it down to much. Didn't like the feel of it or the scratches it left on the cases either.

I prefer the Redding bushing dies. Size with a type S full length bushing die with the expander ball removed. Then you need an expander mandrel die from Sinclair or 21st century. 21st century has mandrels in varying sizes per caliber group which allow you to tailor your neck tension. This will give consistent inside diameter and neck tension, which is as important, if not more so, than concentricity, which is also improved using this method. You will be surprised how accuracy can be improved by finding the optimal neck tension for your loads.

I use a full length sizing die and bump the shoulders back 0.002”. Worrying about runout is a waste of time.

Once fired all I do is neck size from then on

The lee collect dies you'll need to order correct diameter rod for your neck tension with that brand if brass that's how it works.real easy or you can chuck in a drill and remove a little material with sand paper to add tension.one if the best things lee has ever made

It sounds like he was trying to neck size with full length die which can work if preserving brass and adding a little accuracy is what he's trying to achieve.basically he will need a Hornady head space gauge/comparator or sinclair comparator with the inserts for measuring datum line on shoulder so that way he can measure that he's bumped shoulder back .002-.003 for bolt guns more needed for gas guns.
Just start with die backed out 1/2 turn out or more then keep adjusting down until it's bumped shoulder back

Neck sizing is a waste. Watch Erik Cortina video on YouTube who neck sizes today. The guys that compete at the top level sure don’t.

That's actually funny cause full length sizing and bumping the shoulder back .002 is really just a cheap way of neck sizing folks been doing it a long time.the mandrel being dragged through is where inaccuracies are created hence the creation of lee collet die which keeps bullet concentric to bore
Alot of people say they are neck sizing while all along they are just barely sizing the case with a full length die.nothing new it's just knowing what your doing.

How much are the shoulders bumped back with neck sizing dies?

Neck sizing dies do not bump the shoulder.

I didn’t think so. Neck sizing dies and fl sizing dies seem to be close to the same price as well.

Didn’t Forster used to make a neck sizing bushing die that also bumped the shoulder? I really like Forster dies. If I could start over, I’d only have Forster dies. Only have a few now. I just think if you have your die adjusted right, and only bump the shoulder back .002-.003 it’s not working the brass that much. It’s really whatever works for you. Minimal working of the brass is the objective. Several ways to skin that cat.

Exactly people get to caught up in how someone words what something's called.

Forster does make a bushing bump die you describe. I've never used one but I use Forster FL sizing dies in every cartridge they offer for my guns. IMO, Forster makes the best FL die available. Unfortunately, they have a limited selection and I have several rifles for which they do not make dies. Usually have to go to Redding for these rifles.

When I full length size for my bolt action rifles, I do not bump the shoulder, but just keep it from moving forward during the sizing process. When a case is FL sized, it squeezes the base which moves the shoulder forward. For instance I may have a fired case that measures 2.000 to the shoulder, but if the die is not set up properly it may measure 2.002 to the shoulder after sizing. I set up the die to maintain the 2.000 dimension, not bump it back to 1.998.

For a semi auto it's good practice to bump the shoulder back about .002.

Yea I don’t shoot as much bolt action as I used to. Kinda miss it somewhat. Another way I looked at before was the redding competition shell holders. You can use the specific ground shell holder to get your bump dialed in perfect. I only looked into them and watched some vids. When I first started out I can’t believe how much I pushed the brass back as Ok. But making blasting brass for an ar15 you have to have the cartridge fit in maybe 6 different rifles. Fitting the brass to every gun is what counts.

Honestly I think the brass itself matters more than manipulation. Course I'm not a reloading equipment benchrester nit who weighs every grain and compares powder shape lot to lot(Swear I saw a bullseye group do that with Bullseye vs W231!) I do think neck sizing helps in a custom cut chamber but consistent loading practices matter most.

Well if you follow full length die instructions it says adjust die till it hits shell holder but over time people started backing die out further to basically neck size and slightly bump shoulder back if they chose to.not really different than neck sizing then bumping shoulder back with a body die which people will still say they are neck sizing.its not hard call it what you want

Not worrying about run out just happens that's there's a easy way to neck size that produces zero run out. no chasing needed

Folks calls things the wrong thing all the time. One bumps the shoulders back and one doesn’t. Pretty simple.

It doesn’t matter is why I don’t worry about it.

Anyone a little knowledgeable would appreciate what I said and would understand.
Should rename yourself n2 turtles your a lil slow

Lol. If that makes you feel better then, keep on doing what you’re doing.

Are you saying it doesn’t matter, because if the chamber is cut true, it will self align a bullet that may have runout? Or do you mean you use the lee collet dies? I used to test and adjust my hand loads for runout on a hornady runout tool, and I stopped doing it once I was confident in my die setups, and below a certain runout, you can’t really tell if it’s doing any good. I’m a self taught handloader, I didn’t have a mentor. So I’m always trying to learn and try new ideas. I’ve watched and read so many opinions, and tried different things. But I’m still learning. The technology available to the home reloader is amazing. Like someone posted earlier, Its obvious most runout is from the mandrel being run through the neck. I’ve done some without the mandrel installed. This is where these good Forster dies come into play, to get your good neck tension. And let’s face it, there are some bullets that just aren’t any good for precision shooting.

Runout doesn’t matter as much as you may think it does.

Some may disagree with that ^^^ statement.

Reducing run out is one factor, of many, which results in more accurate handloads.
