This achieves the benefits of neck sizing only, in that the brass fits the chamber pretty much perfectly, with the added reliability of a tiny bump in headspace to ensure it always chambers properly.
The only way that im aware of to set this up really accurately is with headspace comparitors. 1/24 of a turn on the die is enough to put you in and out of "the zone" if you are going for only a 2thou bump in headspace.

How I set up the full-length die is by.

1. Measure the headspace of a fired case.
2. Full length size the fired case and then measure its headspace again.
3. Adjust the Die to be closer to the 2thou only bump we are aiming for.
4. Full length size another fired case, and measure again.
5. Repeat till its only bumping headspace by 2thou.

I'll give that a go some time.

What you will not be able to do will be too actually measure your head space unless you have a gauge to measure it with. I have a Hornady comparator for this. There is a possibility you can over work your brass but I have found typically that just touching the shell holder firmly is about right.

I have a full length die. Just always read that once it's been fire formed to the chamber then neck sizing is the best thing to do.

No. All brass will eventually need a full size as the brass gets worked. Neck sizing is good for most cycles but it's important to have brass that fits your rifle. Nothing worse than finding your rounds won't chamber one day one of a multi-day fly in trip.

Yes. I have some that will let a projectile go through the neck.

They all need to pass through, but this may just be a red herring for now. Focus on the basics

How do you fix the neck donuts?

You don't in my experience. Just throw it away and start again.

Mmm throw them away?

Need to understand how in the OP's case the donuts were formed although I couldn’t actually see where he had a problem with donuts? Yet.

With my 284 mine formed in part from neck turning and in part from brass flow over several firings. Some cartridges are more prone to brass flow.

If for example, shooting boatail projectiles and the projectile boatail to bearing surface junction doesn't seat into the donut there isn't a problem. Or for that matter flat base projectiles that don't seat down far enough down the neck to contact the donut.

Otherwise I cut the donut out using a K&M carbide mandrel with the cutter on its tip.

It's 243 brass and in S&B so it's hardly tough to buy new. Heck you could buy bags of brass for the price of a K&M tool. I've got 243Win brass I can't even give away so I think it's all relevant. Also, I think I bought up donuts not the OP so it is probably a tangent a new reloader maybe doesn't need to consider until he has got the basics right (like priming every case )

I will have a look into the comparator.

Do you have a number of firings before you full length size and trim it? I was going to full length size it after 4 firings and trim to case max length.

Do the FL thing and see how that works. I'm picking if it's tight to chamber this will be your problem.
It's not a F Class rifle so to FL size regularly won't hurt. I like to know my neck tension is as consistent as I can get it without getting too wound up about it so I have a preference for Redding Type S dies. My last 243Win I only had a Type S FL die and it was just as accurate as any rifle I have owned. FL sizing every 4th time should be a good start I'd guess but there are plenty of more experienced reloaders on here who may have better advice.

I had one batch of brass where more than half needed trimming after two firings.

I have a nice and shiny digital caliper so I'll measure up the cases and projectiles and see how much the cases need to be trimmed.

I had a mark all around the projectile from chambering. Like it was hitting the lands. Was still an accurate load.

We all make mistakes my mate who is very new to reloading done this the other day

That’s a good kind of mistake it will never go in the gun to be fired
Forgetting a primer not bad
Undersized brass no problem as it won’t fit in the gun
A perfect round with the worng powder or double charge those are the mistakes you just can’t afford you could best case distroy you’re rifle
And at worst Well you know



I tryed neck sizeing and didn’t like it
I found it to be problematic
I use fls dies and bump the sholder 1-2 thou depending on the load
Found this video on YouTube the other day
Makes perfect sense

After a bit of practice you will have your technique and process down and you will be less likely to make mistakes but be aware mistakes to happen to even the most experienced Reloaders make mistakes so you need to double and triple check everything

That's some great advice.

my 1st edition Nosler manual.... has instructions on how to partial length resize,it works for me. gives a neck size and wee bump.....

I have two bits of paper on wall infront of my reloading bench...my pet loads on one and the set of step by step instructions that come with LEE dies.....
