Thread: 260 Rem Neck up or Down

As far as i am aware necking down is a little more desirable than necking up if you have a choice, more chance of donuts forming when necking up, as part of the shoulder is formed into the base of the neck when necking up, often causing the base of the neck to be thicker and needing neck turning to remove it.

A couple of the cartridges i reload i do both and have more trouble with the ones i neck up.

I size up .243 cases to 7mm08 no problems with donuts or any other strange things happening, even easier if the .243's have been fired they are half way there,
donuts are only a problem when neck turning, if you are going to do a lot of .243 cases would pay to get a Lyman M die to expand them much easier than the expander button
in the FL die
