Thread: Casting for an SMLE

I ended up making my own copy of a Lyman M die as well as a 0.318 sizing stem. With my projectiles being around 0.3190 after powdercoating, there was no way they would seat in a standard sized neck. I am using a Lee collet die to size the neck and am finding it very useful for tidying up dented and crinkled necks. I then run them through my neck sizer die to open the neck out. The mandrel has a small step in it so the first 2mm of the neck is sized to be a slip fit for the projectile so you can place the projectile by hand and it starts nice and centered in the case
I still need to make a lock ring for the sizing stem adjuster and I may blue the whole thing to reduce rust. It's made to have interchangeable sizing stems, so one die body will work for most cartridges with just swapping the sizing stem.
