Thread: FL sizing vs Neck. Opinions

"Wouldnt this cause more issues with inconsistency? " not sure what you are asking here.

This is what I do.

For my 308w I have 400 lapua match grade cases and as I fire them (24 per weekend) I throw them in a 3litre systema box until all my 308w ammo is used up. The top of the box has a paper sheet taped to it and I mark it up as I go along.

I then neck resize it, length size it using the Lee quick trim (every time as it chamfers as well) all at once and that goes into another 3litre systema, I have a wilson 308w chamber gauge and I measure the cases as I do this.

I then prime and load and they go into a 2litre systema (smaller so it fits my ammo safe).

I have not bought a Reading 308w shoulder bump die yet but I will. However Ive not had the need yet and I can always use the club's one if I had to. If I found 1 that was stretched I'd inspect it very carefully and if its not dodgy I'd do them all. For 308w so far I have only ever Lee neck sized the cases but then my load at 45gr 2208 is moderate and the massive Millenium actions dont stretch.

I do the same for the 303british cases but I find after 2 ~4 neck sizes I usually have to full resize (if they go into a No4) but once I see that I do them all. For the Pattern 1914 / no3 there seems to be less signs of stretch so the brass might last a lot longer. So I also have a brass manufacturer per rifle, privy for no 4 target, Winchester for the p14, 1943 for no4 wsra. Each gun has its own colour coded systema box set for its brass.

yeah but you're 3 loads that are only neck sized are likely going to have a different neck tension/concentricity/internal capacity than the one you FL size... All of this could result in a slight difference to POI could it not.

Edit: yeah that is what i'm getting at @ebf. If we are searching for overall consistency every shot we should be doing the same process every shot i reckon. Like if i was going to anneal i would see sense in doing it every firing rather than every 3rd firing or whatever.
