Fireforming load for 300RUM brass to 338EDGE

[perry42]

I would appreciate input on a fire forming load for converting 300RUM brass to 338EDGE. I was planning on using 20gr of Unique, COW, and tissue paper.

I just expand the neck, seat a 300 gr SMK over 90 grains of H1000 and shoot them.

Or try 100 gr of RL17 launching Barnes 160gr TTSX's, and use it as a Varmint rig that is my favorite load anyways.

PS: that load translates into 4000fps of awesomeness.
