300 RUM Action converted to 300 PRC

[Okie Whitetail Hunter]

I am looking at buying a Rem 700 300 RUM action and then installing a REMAGE 300 PRC barrel either from X Calibers or Carbon Six.
I have built a few REMAGE rifles (2506/6.5 creed x3 and 6/5 PRC) however I have never build a RUM or 300 PRC.
I have been reading up on it some but was wondering which stock I need? Just a LA stock or something else?
Do I need to run a CIP length mag, like a Wyatt box.

Am I missing anything?

Is there a reason you were wanting an ultra mag action rather than a standard magnum action? Standard magnum actions are sure easier to find

No reason I wasn't sure if the Standard Magnum would work. Just started researching building one had read a few things about using the RUM action.

It will work just fine. Example: I've built 338 edge and 300 rums with Walmart 7mm mag actions. Open the feed rails lightly and you're good.

This seems like a pretty decent price for a brand new rem 700 Ultra Mag action and same place has them in SS for about twenty five bucks more.

Thanks a lot! That is a great deal

A little unrelated so my apologizes, but if anyone is looking for a SA Rem 700 w/Mag bolt face, $278 seems like a very good price as well.

How do you open the feed rails? I don't have a machine shop or anything.

with a file and taking off a little at a time until the base of the case fits through the feed rails. Don't go crazy it doesn't take much

Take your time because you are removing about .010" per side. Light filing if you don't have a mill. Take a rum cartridge and test it every couple file strokes. Again, they can open up quick. Post results.
edit: forgot to mention softening the edges of the feed rails to protect your brass (capt obvious here)

Thanks. Do you know of any videos out there showing this?

So if you have to open the feed ramps why not just use a RUM action?
