Preferred 45-90 brass for paper patch

[Kurt]

I use Norma .45-120 brass cut back for the .45-2.4 and it is good brass for the PP bullet.
You might anneal it for the fires shot and if using a Shiloh the first loading might be tight at the base just ahead of the rim and you might need to use a dowel to push the first fired case out. I did with my Shiloh for the first time shot.
But from there nothing needs to be done except clean the brass and load.
No need for sizing afterwards and .450 diameter bullet will stay put.
A greaser is to wide in diameter for this cut back brass.
My brass is cut back a little longer for my chamber then 2.4.
