I'm just getting into my own loading setup and was pondering this with a co-worker. I read an article that suggested sizing new brass as well as trimming to the smallest legnth in the batch to square up the mouth.

Do you F/L size new brass before loading???

Re: Do you F/L size new brass before loading???
Depending on the brand of brass you have. Not all brass are created equal. Some needs neck resize to iron out any dents. Lapua brass are very consistent at least in my experience. I just load mine up if they don't have any dents.

Yes and no. Most people do tho. Chamfer and deburring is a must.

Some do some don't.For a bolt action it is not really required to full length size for new cases as long as they all fit in the chamber after neck sizing . If they are sticky and the bolt will not close easily then you should F/L size them .
The reasoning behind sizing them all is so you don't have to cycle every case through the action to check it.
I guess to be on the safe side F/L size them but only neck size for the next reloads untill they get a bity sticky then F/L again.
If you are loading for an auto then F/L size each time untill you are more experienced .

I'm using a Redding series A F/L sizing die and the Redding Competition seater. Can you set the F/L die to just size the neck?

Re: Do you F/L size new brass before loading???
All of my NEW brass gets full length resized as well as cleaning the flash hole,uniforming the primer pockets and sizing the brass to the caliber trim to length,seems to work for me getting decent groups at 200 yds.

If they already came full length sized then it won't make a difference. Your going to have to fire them first to fit your chamber then resize to your desired length.

What is your prefered method of fitting them to the chamber?

Re: Do you F/L size new brass before loading???
Load them and shoot them in your rifle. Then measure the headspace on that fired case. Adjust your sizing die to bump the shoulder back .002 less than the fired case and size at least 75-80% of the neck with .002-.003 neck tension. Check length and trim as necessary, load up, shoot, clean, inspect, repeat.

"Adjust your sizing die to bump the shoulder back .002 less than the fired case..."
Actually, that is somewhat excessive, IMHO. A fired case's shoulders are somewhat below the chamber shoulder already because of normal "spring back". Setting a sizer to match the fired shoulder length works good and helps hold case stretching to a minimum.

But, autoloaders will probably benefit from sizing as you suggest.

Re: Do you F/L size new brass before loading???
Yeah I do with new brass. I've gotten some recently that were in crap shape. Necks bent enough that I couldn't run then through the dies without putting a rod in the neck to open some of them up. First time, FL resize them, debur the inside flash holes, and size to length. It's not that much effort and will give you confidence with your new reloads.

Re: Do you F/L size new brass before loading???
I Neck Size, chamfer and deburr the mouths on everything. If it's actually really good brass that I will be segregating out for accuracy use and not just plinking I do the flash holes at the same time before the first load.
I don't see a point to FL sizing stuff that's already at "new brass" spec. It's already going to fit in the chamber of even the tightest rifle I own, and it's going to fireform to a better piece of brass after I'm done and the closest I'll ever go to FL sizing it for a match chamber is to bump the shoulder MAYBE.
Waste of time and potential brass life in my experience.

I full length resize new brass prior to priming.

Re: Do you F/L size new brass before loading???
I do except for the Alexander Arms factory 6.5 grendel brass. The manufactorer says not to on that. It is made by Lapua and relative to the Winchester brass I've used it looks great.

Re: Do you F/L size new brass before loading???
I Lee Collet die the new brass.
That gets any dents out of the case mouth.
I then chamfer the inside and outside of the case mouth.
Then I load it.
No sorting by weight.
No turning necks.
No measuring neck wall thickness runout.

Re: Do you F/L size new brass before loading???
I was shooting at turtlesniper's today and brought up F/L sizing. He made the comment that he F/L sizes every time because he wanted his rounds to fit every time. A little grit in the chamber with a tight fitted case equals a possible fail to feed in a comp.

I don't for Lapua brass. But I do neck turn, chamfer, debur, uniform the primer pockets, and uniform the flash hole...

Re: Do you F/L size new brass before loading???
I did not full size them only looked at the case neck for out of round conditions if there were and then just neck sized them.
i agree all brass must be deburred and checked

Re: Do you F/L size new brass before loading???
Shot with new, unresized, unscrewed around with Nosler seconds brass.
I don't resize new brass. I think all this primer pocket uniforming, flash hole deburring and resizing of new brass is a huge waste of time.
Don't take my word for it though. Do it both ways and see what works for you.
