Hornady 30/06 new brass
Silly question but do I need to resize them first even though they are new unfired and in the sealed package?

Hornady 30/06 new brass
Nope. Load on my friend. Chamber check them if you want. Or measure them. Or both. But they should be ready to roll

I always at least neck size (including running them over an expander).
Usually, I check the length - and uniform if necessary - and make sure the mouth doesn't need to be chamfered/deburred.

'Nope' is absolutely incorrect. New brass is not ready to load. All new cases require checking the lengths, trimming as required(usually not at all), chamfering the mouths and FL resizing.

I don't mess with them until they have been shot once, then they get the full treatment. Been doing that for a long time.

You might get away with not sizing some brass in some calibers sometimes, but definitely not in all instances. I always resize and trim new cases the same as once-fired range brass. Then you know where you stand. Once it's fired in my gun, then I can decide if I want to do anything different.

Call me lucky or whatever, but I load for 22 Hornet up to 460 Wby and have never done anything to new brass other than load and shoot. I do measure certain parts of the case before and again after (ever hear of that before??) shooting. Then give them the full work up. I don't see the need to do anything before they are formed to the chamber.

I full length size new brass.
There is such a thing as shipping. And it's not always handled carefully, shall we say. That and the manufacturing process in itself lends to less than optimal conditions. How many of you deburr the primer pocket? Ever see the amount of brass you get from doing that?

I resize all my new brass, and give them the regiment.
Maybe I don't need too but a lot of mine are tube magazine rifles so after resizing and trimming my crimps will all be consistent. I do this with anything that takes a crimp including my handgun loads. Bolt action rifles probably don't need that amount of attention. |

First time with brand new brass, they get full length sized. After that, I only neck size

They may get the Lyman M die (for sure Lapua which comes with dented mouths and that has to be some drop to do that)
I usually run em in the Tri Trimmer to get the chamfer on them. I will test a few cases to see if they fit ok. I have yet to size any.

For me it depends on who makes the new brass I'm using. Bulk Win, RP, PPU etc. that comes bagged gets a very thorough examination, usually at least sizing and flash hole touch up follows.
High end brass like Peterson, Lapua and some others also get an examination, but usually just results in an exercise of admiration. You get what you pay for. |

Dano4734,
New brass is the same size as is sent to be commercially loaded. If your rifle can't chamber new commercial ammunition, you have a reason to mess with its size. There is another. If you have a case comparator, measure the length of a new case from base to shoulder midpoint. Full length resize it and see if it comes out shorter or longer. If it comes out shorter, then full length sizing the new brass is just increasing excess headspace, making the head stretch further back to find the breech face, and thereby shortening the reloading life of the brass. If it comes out longer, you may actually add a little bit of life to it. IME, usually it gets shorter, however, so I don't usually do it. The soft, annealed necks can get bent at the case mouth, so straightening the mouths in an expander is not uncommon to do. I don't like to use the expander in an FL sizing die because they can and often do pull necks off-axis. I use a neck turning mandrel in the die body Sinclair makes for adapting them to a press. However, a Lyman M die works well, too, and can add a little step at the mouth to start bullets in straight which reduces runout and improves precision.

Reloaders used to think you needed to size new brass. I did when I first started loading. I've seen enough to convince me there is no need. I haven't done so in years and it works fine.
When you buy new brass it is exactly the same brass used in factory loads. They don't size it twice, why should we.
