Bought some brand new 243 brass, measured it---its well within trim length, the neck holds bullets with lots of tension, (had to bevel & chamfer of course), my question is does this brass need to be sized before loading.
thanks......

You can probably get away without it, but:

1. It can't hurt.

2. It won't take long.

3. It might conceivably help.

Take it from there.
 
I wonder why you would bother measuring new brass?
Many of those companies have been making ammunition and components for a hundred plus years. I think they know how to do it.
How long do you think they would be in business if their brass was made so sloppy that you could detect a default in it, by using your cheap measuring equipment?
"(Resizing it) can't do any harm."
How about cutting at least 10% off its life?
Probably more reloaders get less than ten reloadings from a case and your resizing the new brass has just taken one resizing cycle from its life.
Unless you are using lead alloy bullets, you don't have to chamfer new brass.
Just load up your new brass and shoot.
 
sometimes the necks are bent or banged up in the bags when you receive them...take those aside and size them....only the neck needs to be sized for those.

If you need to bump the shoulder on new brass then one of two things is out of spec..hopefully its not your chamber.

This is just my experience...you mileage may vary.
 
When I get new brass I open the bag and prime it, charge with powder and seat a bullet then shoot.

Sometimes for certain calibres or guns I will debur flasholes and uniform primer pockets etc.

This brass in the bag is just as ready as it is at the factory when they use it to load ammo. If a case mouth is dented of course it needs to be partially sized to fix it, but I don't find this to often.
 
You don't have to even size the cases if the neck is dented.Just use the pointed bullet in a loaded round to round out the case mouth and seat a bullet in it.
 
It pays to check

Some guys are pretty casual about reloading. If they haven't blown up a gun yet they likely will someday. Reloading is pretty safe if you keep your eyes opean and check things out.

Jaaaa.... H4831 is pretty casual about reloading. Bruce is kind of a noob when it comes to reloading. I'm sure that once he gets another 50 years of experience, he'll be as good as you.

Personally, I always sized new brass when I took it out of the bag; but I never thought about why I did it... I just did it because, ya know? Now I can save that step.
 
I mostly agree with H4831, lately though I have been doing the front half of the necks because they are really beat up nowadays. I have also found that neck tensions vary greatly with new W-W brass, half sizing the necks solves this as well. Nosler brass however is prime and load no pre steps required.
Back when brass was packed in 20 boxes none of this was necessary. I have also taken to chamfering inside of case mouths as I collapsed a few brass trying to seat flat base bullets without doing it and that really pi$$es me off, having 49 or 99 new brass. The new bulk brass from W-W has quite a burr or flare inside the mouth on some of the cases.
I used to like the days when you could buy brass and load it, no brainer, nowadays it's either pay big bucks for Nosler or Lapua or do some of the finish case prep work yourself.
Remington is better finished but not as light or hard as W-W, so I'll carry on doing a little more pre-load prep work to use W-W brass.

I'm usually so far behind it looks like I'm ahead. But I haven't blown up any guns yet. All I'm saying is it doesn't hurt to fondle your brass.

My sentiments exactly,I find about 15-20% of the bagged brass I buy needs the necks ironed out a bit but that's about the extent of it.
 
I've always sized my new brass, chamfered the inside of the neck and de-burred the flash holes .

When re-sizing some new .264 Win brass, (from a unopened, sealed bag) came across
two .300 Win Mags. within the lot. Certainly wasn't on the lookout for anything strange, and easy enough to miss with the .264's ... untill you try to size them. :D
 
I pretty much always have to resize new WW Super brass from Winchester. The necks are often oval or dented. I run them through a full length resizer and don't need lube as it only touches the neck. I put a thin coat of lube on the necks none the less. Every time I have tried to load WW Super brass out of the bag I end up with at least one or two crushed necks when I try to seat round bullets in oval holes.
 
Just bump the brass into the die and over the expander ball to true up the necks.

No need to do a full court press on them.

Chamfer and de-burr, and prep as you would any other brass.
 
unless using lapua ,norma etc i do in batches of 50. i resize, check lenth, cleanup the primer pockets and flash holes inside and outside chamfer the necks. doesn't cost and keeps me happy. most of my brass is worn out before ten firings anyway due to loose primer pockets..
