I have what you are looking for.
It is set up in .358 configuration right now. It is near and dear to my heart though, so it will not be cheap.
I just joined here today, but have 100's of all positive feedback on gunboards.com and the m14forum.com under the same username,.... ripsaw
Also have feedback at the new M14 forum I got started recently at the CMP website under username M14.
Send me a pm if you are interested, with your email, and I can get some pics taken to send to your email box.
I joined here to figure out where to get a sizing die for it to do .308 projectiles in maybe a .309 sizer. I just started casting for my M14 recently and pulled out this old Star sizer luber.....best regards...rip
