I have always sized new brass but I always read Lapua is the cream of the crop.  I'm wondering if it is really needed prior to loading it up.

I use Lapua brass exclusively for 1000 yard competition.  I use their .308 Palma and .260 Remington brass.

I have sized some new brass before use, and skipped the sizing on some other batches.  I have noticed no difference at the target associated with either practice.  

However, after firing once and then neck sizing, the rounds get more consistent than when new.

Conclusion:  Size, or don't size, doesn't seem to matter in my experience.  Once (or more) fired brass is better for precision loads than brand new brass.

It's a long bumpy ride from Finland to your loading bench.   Lapua is the best, but even the best can get dinged and dented necks during shipping.  I at least neck size all New brass including Lapua.  Once  the case mouths are all nice and round I chamfer , deburr and uniform the primer pockets.

I have two boxes of their .223 match brass, and haven't found the need to size any of the brass.

Never sized a single one of the 1000 case batch I got.  I had zero problems shooting loading/shooting them.  Surprisingly I had no dented case mouths.  But for safety you should always resize new brass.

I run all of my brass through the same process.   New or used

Always FL resize new brass.  It does not matter what brand.

Bushing bump neck size at a minimum.

Try a few. If it runs through the die very easily than it is good.

My experiance is that some of the new brass will be okay and some will benefit from a run through. I do that for all the new brass I use too.

If you are competition loading you should do the same thing for each round which means resizing them all new so when you RE-load they are the same.
