Neck only re-sizing dies

Try a Lee .303 collet neck sizer die. Works fine for me. No lube needed. You can turn down the mandrel a thousandth or so if needed.

In the past, I believe 'parashooter' and others have suggested using the Lee 'Collet' Re-sizing Die for 7.5X55mm Swiss.

When properly adjusted, it de-caps the case and sizes enough of the .30-40's long neck to give a good grip on Jacketed Bullets. There is no need for any lube and it is quite gentle with case necks.

I think RJ already has the dies he needs to do a fine job of loading for his Krag. Why spend more on dies that won't enhance results?

Lee collet dies are interesting, effective, and pretty much unnecessary to achieve his stated goal: "longer case life".

When selecting collet sizers for off-label use, critical dimension is bolt face to neck/shoulder junction. 46.6mm for .30/40, 47.4mm on 7.5x55, meaning 7.5 die will size to about .8mm of neck origin on fired .30/40 case. Nice, but probably not worth spending some $25.
