    I was thinking of ordering a expander mandrill (.263 & .262) should I also switch my dies out to a FL bushing die or is a regular FL sizing die with the expander ball removed going to be good enough

    I use my Expanding Mandrel Dies with regular Full Length Sizing Dies. They work wonderfully.
    Many don’t use a Mandrel with a Bushing Sizer, but it will work fine with them too.:thumbup:

    You can, it will just work the brass a little more than needed. Will that matter? Might not at all.

    The vast majority of rifle reloaders just use regular dies with expanders being part of the decapping pin.

    What is your situation where that is not good enough?

    I use mandrels with bushing and non-bushing dies . With a bushing die you can dial things in and work the brass very little . Some FL dies size the neck much smaller than a bushing die because it relies on the expander ball for neck ID . So by using a FL non-bushing you may work the brass a little more expanding it . Like Walkalong stated...will it matter ? Might not at all .

    I use a forster die with the expander removed and a 21st century mandrel currently. I need to have the neck honed to reduce overworking the brass just on other projects currently.

    This.

    I prefer bushing dies over standard dies, always, but in the absence of a bushing die, a standard die without the expander ball, chased by a mandrel expander is the next best option.

    I had a benchmark #13 Med Palma put on a Tikka action. I was looking for a little more accuracy in my neck tension. I need to work up a good hunting load for this new build.

    You can use guage pins or order a series set from 21st century

    Sinclair and 21st Century Reloading both make excellent mandrels and die bodies.
