    Bushing dies

    I don't understand the concept/ how to use etc , could some one school me on these please.
    Are they better than standard, better than a lee Collect neck die?
    Thanks.

    Dunno if they're better than anything else but they are basically a normal shoulder bump die that allow you to size the neck to a specific size via various sized bushings.
    Which in turn is neck tension on a specific projectile.
    The die will not touch the neck without a bushing in it, just bump the shoulder if setup to do so.

    Your normal full length die will size the neck the same on every brass projectile combo.

    I use them and like them. Really good for reducing ES of certain combos.

    But I have had just as good of results with normal dies.
    Never used a collet die.

    Cheers.I guess what I'm not understanding is why there is a need to size the neck to a specific size instead of just a standard resize?
    and how do you know that you want a specific size?
    Run out etc maybe?

    Theory is to seat a projectile and measure the neck.
    Whatever that measurement is get a bushing that will size the neck 2 thou less.
    For example my 260 is .294 with projectile seated. So a 292 will theoretically give me 2 thou tension for that specific brass projectile combo.

    I use 4 thou on one cartridge and still get excellent ES

    As I said normal dies can be perfect.
    For hunting ammo used within normal ranges I wouldn't bother with bushing dies.

    and if you neck turn, you need the ability to alter the dia of the part of the die that sizes the neck, as a standard FL die often wont be able to size a piece of neck turned brass enough to get enough neck tension.

    Just to fuck with your head a bit more standard dies size the neck to much over working the brass,
    also the expander button can stretch the neck out of square, Redding S dies give you the option of using the button or not
    A bit more shit to sort, I shoot mainly cast lead bullets and use a Lyman M die to expand my case necks it pushes down so does not
    stretch the case neck I use it when loading jacketed bullets as well none of my full length dies have expander buttons,

    You can load perfectly good match grade ammo with standard die sets all the fancy gear may make it more consistent and a bit easier
    to assemble your ammo but is it worth the money

    I'm the same as @R93 on my 260 but I don't use the internal expander button, for the reasons shooternz mentions. Not using the expander also saves having to do inside neck lube. For hunting and plinking loads, a collet die will give the same results.

    I haven't used an expander button on any rifle loads for years.

    Maybe once in a while on a dented neck I think I can salvage.

    That's another reason I like redding dies as they have a cap for the decapping pin that will not touch the sides as in my pick above.

    Sorry mate, you're right. I just checked. Has the button on it. Haven't loaded any 260 for ages.

    Now I can't find my friggen knurled cap

    @jakewire Redding do two types of bushing dies, a plain neck one or a full length one which allows you to bump the shoulder back, which you will eventually need to do if just using the neck one (back thru a normal full length die or a body die) the advantage of the neck one for me is it speeds the reloading process up, a lot less faffing around prepping & cleaning brass!

    If you really want to have sleepless nights, get a concentricity gauge
    Shut up, get out & start pushing!

    Get a forster bonanza press, redding dies and you shouldn't ever have a concerntricity issue if using good brass to start with.
    Die floats, case floats in case holder.

    Only time I ever had an issue was with a bad die after annealing.
