I would consider the 375/338 LM but I don't see much advantage over the RUM. Also if I go with the 375 Tejas I can use some of my father-in-law's brass while I am working on getting brass of my own.
The biggest advantage of the Lapua is the brass. It is wayyyyy better than Rem RUM brass and will last a lot longer. If i was going to do a Lapua anything, I would do an improved version. That will get you about 10% more capacity than the standard RUM. Not sure of the Tejas specs, but there is very little room for improving the RUM case and getting much more capacity. Another advantage of the Lapua is it is .130" shorter than the RUM which allows you to seat the longer bullets more efficiently.
If you can make it work in your budget, I HIGHLY recommend a custom action for theis build.
