    Hi,
    New here.

    I'm getting ready to buy a 270 Weatherby Magnum. I intend using Norma brass & Barnes pills. Not sure about powder and primer.

    I've been told there are differences in reloading rimmed cases. Any tips.

    Thanks in advance.

    I've been doing this over fourty years and have found NO reloading differences between any bottle neck cartridges; rimless, rimmed or belted. I size and load them all exactly the same way, they all work good. I've READ a lot of meaningless blather on the web about the 'differences' but haven't yet seen any, nor have I seen any authoritative books or loading manuals pontificating on what to do different with different cases.

    Boomtube,
    Sounds good to me. I just had some say that they had problems with swelled cases and something about difficulty headspacing from the rim rather than the shoulder. Thanks for your advice.

    What ever way your gun likes belt or shoulder. My 7mm rem likes off the belt. A friend of mine likes has the same 7mm rem and it likes shoulder. The swelled cases prob is a issue that all cases suffer from to a degree. But I have never had any real issues that I don't get with my rimless cases.

    Hi,
    So an FL resizing die and competion seating die is all I need? What do you think about a neck sizing die.

    Do you mean belted? The .270 Weatherby mag is a belted mag, not a rimmed case. The 30-30 is a rimmed case. All H and H based cases are belted. As far as load info, H 4831 ssc is a good starting powder. Info on load data is avail on Hodgdons web site. Or go to IMR powder.com. ( same website).

    Nothing wrong with having all three. you will need to F.L. size every few loads. Just enough to size the body. This will help with the bolt being hard to close, lets say every 3 shots. And have a good time. Loading is great.gun)

    "So an FL resizing die and competion seating die is all I need?"

    Yes. And normal seaters are usually quite good; it's rare for the only two good comp seaters (Forster/Redding) to add anything useful for new guys, not for a long time.


    "What do you think about a neck sizing die. "

    I think a neck die for such a cartridge is a waste of money. Most factory sporters shoot best when FL sized so the shoulder is the same, or slightly back, from fired location anyway. Most cases fail due to neck splits so case life isn't helped IF the cases are neck sized in a common neck die; they will be worked just as much as in an FL die. (The ONLY exception to that is Lee's Collet Neck die but even then the case life expectancy difference isn't a lot.)

    Headspacing is in the chamber, not the case. We want our cases to fit snug but not tight or loose so knowledgeable handloaders disregard the definition of how any bottle neck cartridge is headspaced, all we need do is size so the shoulder isn't too far forward to chamber nor set back so far the body has room to stretch and cause an eventual seperation at the web.

    Part of the advantage of handloading (as opposed to simple 'reloading') is to make custom ammo for our individual rifles, not everyone else's. Meaning, rimmed, rimless or belted, bottle neck cases all need to be sized so the shoulder is set RIGHT to fit your chamber, not according to some esotoric SAAMI specification or 'drop in' case gage for all rifles ever made for that cartridge forever and ever, amen.
