If its new from the factory it should be in the correct tolerances.
You need to do a quality control
On the contrary, all fired cases need to be checked for full length dimensions, the above post was I am fairly sure meant that full length SIZING was not required, just neck sizing, if you have a soft case that flows forward on first firing, & you reload the case without a length check, you could end up trying to chamber something that is too long!.NP Muntjac, only too glad to be of help.
Although the contrary may seem evident, I am not sponsered by the writers of THIS book, nor am I Richard Lee himself, and I do realise that I keep preaching on about THIS book in various threads throughout this forum, but I really can't recommend it enough.
One final word I will say, is that if you intend to use the brass in the same rifle everytime, I would avoid full length trimming too often. The brass will 'fire form' to the rifle chamber in question, and will usually only require neck sizing after the initial full length check/trim of the new brass. Full length trimming everytime will result in massive brass flow, causing work-hardening which will lead to extremely brittle cases that could split easily and will certainly not last half as long as they should.

. A fired case, no matter what chamber it was fired in, should always be checked for size (over all length) on every firing, & if it has not flowed forward, then it cannot be cut anyway...... never the less, the check should always be carried out,. it's too late when you cannot chamber your cartridge when need arises.One final word I will say, is that if you intend to use the brass in the same rifle everytime, I would avoid full length trimming too often.

If you set up an FL die properly to only bump the shoulder back 0.001"-0.002" max there is no reason not to FL size unless you are a benchrest shooter using a single case for an entire match.

when i got some new nostler brass for my 22/250 i didnt full length size it. i loaded it up and shot it. then just neck size after that. of course i check the length of the brass after each firing.
well i understand its good to have your brass the same. most of the top brand names of brass shouldnt really need full length sizing when had new. i guess it depends if you feel the need to
