Re-Sizing NEW Brass?

[Richiee_Nankz_Knivez]

Had a debate with a friend about Re-sizing New brass last night

He says you don't need to and hes shooting clover leafs at 100 m

I say you do and i also shoot clover leafs at 100 m

I'm starting to think i'm wrong!!!!!!!!

Is this just a preference?

 

[Muir]

He is wrong, you are right. Do a search on the subject. ~Muir

Each to their own buddy, if your way gives you the warm fuzzy feeling then crack on.

I always open up the necks and resize otherwise the neck tension is too tight from the start.

 

[Mog]

I 'm of the opinion you right, if you don't at least neck size with your dies how can you get consistent neck tension between your new and fired brass?

Whose using Nosler Custom?

 

[phaedra]

I run all new brass through a full length sizing die, mainly to make sure there are no neck dents from shipping.

 

[stubear]

I always would personally - what you dont want is the factory sizing on the new brass, you do a load of ammo up and it shoots great and then you resize it with your die which is slightly different and then your accuracy starts to change slightly.

Ultimately what you're going to be shooting is your resized brass as per your die, so start with that.

 

[muddy42]

Surely logic dictates by re-sizing, you have nothing to lose and only consistency and accuracy to gain.

I've never resized new brass. I do run a mandrel through the necks to take the dings out.

I wouldn't resize new brass. Why waste all that time resizing when it's ready to go.

I do the exact same.

Mainly so you don’t have to waste time working up new loads when you resize your now once fired brass with your own set of dies.

I circumvent this possibility by buying HPS FMJ target rounds in Lapua cases. I use them as a control on the state of the scope and rifle at a range session...tells me whether oddballs are me and my rifle, or my load. Then resize and reload with hunting bullets thereafter.

100% agreement. If you full length resize your new brass, it is, on the second loading, as close a replication of the first loading as your equipment will allow. This is the correct way to handle new brass if consistency is your goal. ~Muir

Many years ago I was loading some new 25-20 brass, assuming there was no need to run it through a die first, to at least have the necks properly and consistently sized. As the result of pushing bullets into necks that apparently were too small, I ended up with a bunch of cartridges that had buckled a bit, and bulged out just enough at the neck so that they wouldn't chamber in the rifle ... lesson learned. Any new brass I load gets a run through the die, checked for length, and chamfered in and out.

Necks on lapua brass are getting smaller.resize all the time

Smaller in diameter or neck wall thickness please ?

 

[palo]

Smaller in diameter or neck wall thickness please ?

I always found them smaller in diameter. Once I run them through a Mandrel their fine.
If the necks are badly dented I would neck size them .

 

[hedge hunter]

As palo says I had too put them through a Mandel.i now resize all my brass first

 

[Odders]

I always full length resize new brass. These days I use RCBS X dies, so it gets trimmed 0.020" under standard trim to length as well, along with primer pocket uniforming & flash hole de-burring.
Dunno if the latter make much difference but it occasionally keeps me from shooting slugs & snails with an air pistol out of boredom.

 

[Cooter]

I do the same as Odders in post #19.

I also neck turn all the brass I get after fire forming, and found it made a significant difference to group sizes and sped up load development.
