f:P: Figured I'd get the face palm out of the way first so if this is waaaay out there you just nod to the face palm and move on to the next thread...

I'm thinking of getting a barrel chambered in 338-300 SAUM, for my Savage 12 VLP. I'm making some assumptions here but if I seat them long it looks like 2700 fps wouldn't be out of the question for a 250 gr HPBT. That strikes me as being a really nice compromise between ballistics and barrel life.

Here's the crazy part (or maybe just plain smart), could I have a 338 RUM reamer run in about 0.76" short to create a similar chamber to 338-300 SAUM and then have a set of existing 338 RUM dies shortened the same amount to make a die to match the chamber?

Is this possible or am I just creating major headaches to save on the reamer and custom die set?
 
Because of the body taper, and diameters I don't think your idea will work. However, Why not use a 300saum reamer, and a 338 neck and throat reamer. For a sizer, I would think you could run a 300saum die with a 338 bushing.

You could just order the proper reamer - I believe ptg lists it. Nice round by the way!

Just wondering if it was practical, I thought since the brass would be slightly bigger you might be able to just stuff it in the die and have a 338-300 with slightly smaller dim. I'll be ordering a bolt head and go-gauge from them if I go forward with this so I guess it's time to add a reamer to the list. What else would be needed assuming whom ever I get to do the work won't have done this chamber before.

I see there's a similar cartridge based on the 300 WSM, the 338 Redneck. I'm working on the assumption the longer neck will be better for seating the bullets long and the reason I'm looking at the 338-300 SAUM.

**Just realized that head spacing it would be difficult if I don't use a proper reamer and go-gauge...**
