    I will be interested to see if you can see the difference or it just gets lost in the noise of all the other factors that come into longer range shooting.
    And if you do notice a real difference between the two brass preps whether then annealing that 30 bring them into line without neck turning.

    Correct. And even quality cases like Lapua and Peterson have variation. My last lot of those 2 brands in 308 displayed around 0.3 thou variation albeit a very narrow band. One of the worst in the quality line was my 7,5x55 SR Norma cases.

    The other thing is if using brands that have wide neck thickness variation eg 1 thou and sometimes worse , turning may fix that but usually there is an accompanied bad weight variation. Weight variation can be assumed to be capacity variation ( some would argue not, water capacity testing is the only accurate neasure).

    And yes the other one I have had is an indivual case that no matter what, always displayed runout when reloaded.


    PS: @small_caliber I still have a box full of Precision Shooting magazines going right up to the time it folded (with half my annual subscription left to run). The quality had dropped off in the last years but still some excellent reference material in them.

    Yep I have one of those to.
    People ask me about them and I tell the best thing they can do is smash them with a hammer till you cant use them.
    I have tried shooting my straightest and most crooked ammo on the same day and there is no noticeable difference.
    The ammo I make I cant shoot better than so no point mucking around with it.
    In saying that I induction anneal every time as that does.

    If so at most I would suggest.
    De cap
    Clean primer pockets
    Anneal (more important for big magnums)
    Clean/ tumble if you like post cleaning
    Full length size
    Trim
    Chamfer
    And load those bitches up
    Others may have other ideas but that is the most I would do for hunting ammo.
    It's all I do and for a long time I didn't even do half of that when I started with my 270win.
    yep that's what I do when my brass needs a tune-up after being reloaded 6 or so times

    My mate had a crappy shell holder with way too much slop and and it wasn't even level. It even caused the cartridges to fly out of the autoprimer. Needless to say the finished ammo was banana'd and shot like crap,
    i bought him an rcbs one and now they're within .002" RO which is a vast improvement.
